Oxygen Not Included - Tutorial Bites - Sour Gas Boilers

[@GCFungus]

Hi everyone, I thought I should post an update to this with some further testing. As a couple of people have pointed out, the design as shown has an issue where methane can condense in the airflow tiles and then teleport across into the supercoolant area. To resolve this issue, I removed the top 2 airflow tiles on the right side, and the top left tempshift plate in the condensing area (so the 3 tiles in a row) as shown at 8:52. That seems to have done the trick, but also feel free to make any more improvements you can think of!

[@markalvarez1827]

I love your videos, you are 1000% better at me than ONI but I want to ask, with all the sulfur output couldn't you split it between sweedle and grubfruit then use the seeds from grubfruit to feed a 25 gulp fish tank that would purify the polluted water at 200g/s each (5kg/s) meaning less power used for water conversion and more free food that could be combined with the sweedle meat to make surf n' turf? Industrial brick is just a "waste" if you are already generating 50KW+ of power in the first place! I think we both know you have the natural gas for a grill.

[@GCFungus]

@@markalvarez1827 That could be possible, but saving power with a 10kg/s sour gas boiler is mostly not worth it since you have so much power. And pacu can simply be starvation ranched anyway (I do need to double check this with the latest patch), so there's nothing stopping you having cooked seafood anyway. The industrial brick is never really a waste, it's about containing the machines, the cooling and their produces whether you make it hot or cold. The nat gas gens still need cooling and still produce polluted water and carbon dioxide that must be dealt with.

[@natezschoche3045]

I would also add, I had an issue with Natural gas appearing outside my boiler and I was very confused by it, just not that it's a good idea to set the conveyor loader to Sulfur only, and not everything, otherwise it will pick up the solid methane if your boiler gets too cold which is what mine did!

[@atellismarin4607]

I built this recently but the change as you described didn't work for me, though I will admit I may not have implemented it properly. I did find a simple (mostly)stable solution. I moved the chamber with the tepidizer to the right one space for simplicity I moved the gas pump in the very bottom left to the top to the left of the others. I say mostly stable as the teleport of frozen methane does still happen and it shoots up the dividing wall between sour and natural gas an out the top where I have another pump in a small room to collect it. I have had this running for a very long time and observed no other issues.

[@AceJohnny80]

I love how, for the power distribution with the smart batteries, you’ve effectively reinvented the Switching Transformer, the common small charger of all our real-world electronics.

[@oBseSsIoNPC]

Jesus this is about as compact and efficient as it gets. What an incredible design from start to finish. I didn't even know this existed...just wow what this game is capable of providing.

[@andregon4366]

I mean, the cold sulphur could go through the steam area to take care of the cold problem. Either the boiler or the powerplant would work. That would compact even more.

[@trungquyenha9951]

Hey hope you see this comment, I've watch many tutorials before but till now you are the only one that draw out the diagram this clear. Thank you.

I love the detail and dedication you put into every single one of your videos. Those are actually one of the subscriptions that I really like to get notifications about and watch immediately. Wonderful work and I often even rewatch the matching tutorial bite before starting the build, just to get detail reminders about material limits or specific design details you may need to watch closely. Thank you for the great content, and I still don't understand why you are 'just' at a bit below 3000 subscribers. Absolutely underrated content!

[@michaelsotomayor5001]

Thank you for adding the process and benefits on your videos. In this case I'm dividing everything by 10 because, you know, spaced out small asteroids. I'm building 1 sour gas boiler to keep my 3 dupes alive on my "oil" planet; it'll have enough food and continuous energy! edit: may I add only one tip here, put your super coolant in a liquid reservoir adding an extra overflow of super coolant. Instead of having empty packets in the pipes, which stutter the TAT, it will have constant full pipes of super coolant which doesn't slow down the TAT heating up.

[@GCFungus]

Thanks for the lovely comment! I do try and consider the videos carefully from the perspective of the viewer who doesn't know the topic, so it's important not to assume too much knowledge. I also always try to keep in mind the question of why. Why are things the way they are, and why does it matter? All good informative videos need to have a point and I always make sure to include a "so what", so that ensures people can take something away from the video rather than just saying a lot of information.

[@YakubMyBeloved]

thank you algorithm for giving me an excellent tutorial and a new oni content creator

[@skrolle]

Awesome tutorial, two small things: 1) It's easier to just pour a layer of liquid on the steam turbine for cooling, than to fill its room with hydrogen. Better thermal conductivity, and you're not stuck with the piping. 2) POWER THE AIRLOCK DOOR! There's a bug when the game can mix up the state an unpowered door is in, which breaks the heat injector.

[@robbmanes]

Your tutorial bites are legendary. Thanks!

[@posi_de]

As always a great video - I wish there was a remark in the video to check the pinned comment(s) for updates for these complex designs: I had several issues with e.g. the petroleum boiler or the CLRR which where discussed (and often solved) in the comments. Same here with the 2 airflow tiles/tempshift plate. I have a small issue with the pipe block behind the pumps which get some damage during startup but does not get worse now. A bit serious is conveyor rail which runs through the isolated tiles: they get warmer over time and melt the sulfur. I moved the rail one tile higher which is working fine now. I also recommend building the whole thing inside of a vaccuum chamber as it gets hot over time.

[@mikelmazzi7978]

As always great video. People can see the love and effort you put in your videos. Keep up the great work :)

[@Temstar04]

I find that in most cases people don't need a 10kg/s sour gas boiler, particularly in a spaced out cluster. I highly recommend smaller 1-3kg/s sour gas boilers that use radiant liquid pipes and that "1kg liquid packets can't burst pipe even when super heated" trick for counterflow heat exchanger. You can pack a boiler into a tiny volume with those, or alternatively with very tall heat exchanger towers run them with very low energy input.

[@allenbythesea]

The fun of this game isn't necessarily 'need' though. Something like this helps us enjoy the game in new and interesting ways.

[@Kris_Hagen]

I'd love a save of this for easy blueprints. Especially for the hot industrial brick. I'd love to see the piping and automation for tepedizers and the aquatuner, as I can't quite figure them out. The boiler itself was pretty easy to follow along with in sandbox. Can't wait to try it out in game. Never built a boiler before with almost 2k hours played, lol. I'm also having some technical difficulties with the boiler in sandbox. Happened couple of time, but natural gas would get too "hot" inside airflow tile and pop up into the super coolant room. And some of the ceramic insulated pipes carrying methane would have breakages.

[@GCFungus]

So for those builds you specifically mentioned, the tepidizers I use are the tricked out ones that I demonstrated in the heating tutorial bite (as they are for heating), and the aquetuner cools the steam turbine in a standard cooling loop as I showed in the cooling tutorial bite. Another viewer did mention the similar issue with the methane getting into the supercoolant area, but I've not seen breaking pipes. To be honest I don't think I ran this design as long as I should have to be 100% sure it was robust - and as I did warn in the video these boilers are just the most temperamental designs in the game. I'll soon build this in my Most Dupes Run and see if I can solve any issues.

[@Kris_Hagen]

@@GCFungus Thanks, I'll have a gander at the heating bite. The methane sneaking and pipe breaking happened early in the startup, so might be that temperatures were not at optimal stage yet.

[@Kris_Hagen]

@@GCFungus I did wait until around 540C to start with the oil in my game, and the boiler has now been running for almost 150 cycles with no issues what so ever. Not counting my own failures of forgetting to replace an automation wire after vacuuming and not filling cooling area with enough super coolant, thus causing some scaldings.

[@michaelrichards5340]

This is the coolest thing ever! I've been playing on an asteroid with no natural gas and I was wondering if I should ship it.. Or just build one of these and honestly I wasn't sure I had it in me but after seeing this, I'm gonna go break some legs lol at least the final aim is sour gas and not petrol liquid like the petroleum boiler, can't mess up that big. Thank you so much for this, I've seen so many videos on this and it never seems as clear as you did, also thanks for always mentioning materials and showing settings and backgrounds and explaining why. I have so much of your rules and builds in my head now lol

[@GCFungus]

That's awesome to hear, these builds really are fun but can be a complete pain too! I'd love to know hot it goes, hopefully well...

[@michaelrichards5340]

So I was finally able to put it together after a long scavenger hunt across the star system lol farming super coolant material, digging thru the volcanic planet to the therium materials, realizing wolfamite was right under my nose (think I butchered some of those spellings) But after doing all that successfully, with your instructions I was actually able to put together this and parts of the industrial side, this was actually really easy, though I can't say if it was my approach or experience, that helped me, but what I definitely knew helped me was your one step processes, knowing which materials to use and where (previously things I've built from KZbin had weak materials working against me in the wrong scenarios) for builds that worked... Just not for me but my only two issues with this is... Mainly on my end, I did start this up, it did magically turn into sour gas then sulpher + methane then natural gas (usually I blow things up) My issue is when the new oil came in, it didn't immediately turn back into sour gas again, it actually decreased the temperature by 200 moving me from 540 to 338c.. My question is, was this because I have oil coming in at 19c? As my fear is, presently my AT has Super C at - 257c and the metal tile where the oil sits is 338c so by the time I get back to 540c wouldn't my coolant become solid and break the pipes? Or am I thinking too simple? Besides my personal screw ups this works, and it works really fast and really well, this is my first complex build and I've learnt a lot, like how template shifts actually work, the vacuum door effect is clearer to me now, many things I've learnt here I can apply to my personal experiments

[@GCFungus]

That's awesome to hear! The oil input temperature I assumed was 87C, which I have found to be the stable temperature an oil well will produce at if left uncooled. The difference in temperature may well be the difference, but 4 aquetuners should be overkill to absorb that. Did you let the steam room fully heat to 700-800 degrees? If it then keeps dropping and dropping then heating the oil input will make the difference. Supercoolant is the only material in the game that doesn't freeze, so you can get to absolute zero with no freezing problem. This would cause an issue though because the aquetuners can't remove heat once at absolute zero - this may be linked to your heating problem. The liquid tepidizer is needed to keep the coolant hot enough to be able to remove the full 4x14=56 degrees of heat. If the super coolant is coming out past the tepidizer at below -220 then you likely have an issue with the tepidizer so double check that.

[@michaelrichards5340]

Wow! I didn't know that about super coolant lol that is interesting, based on my check here everything is within your ranges, I have the room under the 800c mark yup, so like I thought, I'm the problem because I ran my oil thru a cold biome no insulation and it stayed there while I was building the Sour Gas... I have a phobia of heat and lack of water in this game so avoid both even when I don't need to. So I'd have to reheat my oil and get new sources from the well which will cure this issue. Even so this is a very cool build, I definitely owe you some likes and promotions lol

Top notch breakdown

[@Roseh77]

Built it and it works like a dream. One thing though, and I noticed this was happening in your build, a frozen piece of methane periodically ends up in the tapidiser chamber. There doesn't appear to be anything I can do about this. More and more of it keeps building up until it eventually liquidises and I end up with a chamber that's half super coolant and half liquid methane.

[@GCFungus]

I did mention the fix for that in the pinned comment. If you remove the top airflow tiles and one tempshift plate it will resolve the issue.

[@dominicksolerix2703]

Amazing. Something I look forward to never touching

[@Yog555]

A note on the cooling pipes - I built the radiant pipe segments in the condenser area from steel and the boiler stalled out, the cooling loop couldn't transfer enough heat to keep the SC reservoir and thermium tiles to condensation temperature even though the SC in the loop itself was well under -200c, with the ATs stuck at maximum cooling. It would only condense in brief spikes and then creep back up above temp. Pulled it apart and replaced the radiant segments with aluminium (didn't bother testing gold or copper) and it came back to consistency. Also don't make the insulated pipes in the steam room from granite because they'll melt, ask me how i know.

[@GCFungus]

Yes the radiant pipes I used were thermium for the best heat transfer, which you should have for the aquetuners anyway. Steel is actually not a great conductor and is beaten by most refined metals. The reason it is good is that it's better than metal ores, so is better for things like mechanised airlocks and radiant gas pipes. Aluminium is obviously great at conducting too, but you can't use it in the hotter areas here as it will melt.

[@glennjanot8128]

I play on Baator, and I currently have roughly 700 tons of Naphtha in my infinite storage, with another roughly 2000 tons in various pools around the map still waiting to be sucked up. Plenty of Sour Gas without having to pull oil from wells :D

[@thejoshernut]

Just a heads up, I just built this exact machine. 2 minutes after starting it up my FPS went from about 50-ish at 1.5k cycles down to about 8 fps lol. If you have an older setup you prooooobably don't wanna build this exact boiler 😂

[@AdamRotering]

So I built this copying your build. Then my vscume area ended up flashing sulfur somehow. So I got it out. Ended up having to break in and fix a few things. And rebuilding my insulated blocks. Got it all rebuilt. And working again. Untill I realized all the liquid methane is poping though my blocks into my supercoolant pool over the tepidizor. No idea how or why. Might have to start over from scratch

[@GCFungus]

I addressed this in the pinned comment. If you remove the top 2 airflow tiles and the top left tempshift plate in the condensing area it will solve the issue of methane teleporting into the tepidizer area. Flashing sulfur I've not come across before, just be careful with the routing of the conveyor rail.

[@maxarturo78]

The scheme is excellent, I was just thinking about repeating it, because I got a world where there is not a single sulfur geyser (Skewed Asteroid). I have already ordered my duplicants to produce 8 tons of Thermium and 60 tons of steel 😎 For the main part (the boiler), everything seems to be clear, but I have a question about Industrial bricks, Due to which the resulting contaminated water is boiled in the lower part? I see that there are several water heaters there, but they seem to have a maximum temperature of 85 degrees; and the only Thermo Aquatuner in the upper part is intended, as I understand it, for cooling steam turbines.

[@GCFungus]

I explained in the Industrial brick Tutorial Bite, and in the Heating Tutorial Bite, and the tepidizer is tricked using a thermo sensor and a not gate to rapidly pulse it allowing it to ignore the temperature likit and submerged requirements. This does only work up to 125 degrees effectively but is a great way to boil polluted water, if a little exploity. You can of course use an aquetuner down there but you would likely need a tepidizer to counteract the extra cold made (I explained that in the Heating Tutorial Bite too).

[@maxarturo78]

@@GCFungus Thanks for the reply) I came across an interesting bug: solid methane is gradually accumulating in the left cell of the tepidizer...

[@GCFungus]

@maxarturo78 Yes I explained the fix for that in the pinned comment.

[@1x4x9]

With longer counterflows on both the hot and cold side you could reduce the requirement from 4 aquatuners down to 2, saving an additional 2.4kW of power. All it costs are size/space and materials.

[@GCFungus]

That's true, and I did mention in the video you can actually get it to 1 if you make it really long. Even with this design the 4 aquetuners don't run all the time, and for any boiler the power consumption is purely determined by the heat exchanger efficiency and not the amount of aquetuners. If anything my design could probably run with only 3, but I'd rather have 4 running 75% of the time than 3 running 100% of the time because you have more headroom to correct over or underheat. Of course if you want to adapt the design or just straight up make your own then everyone is more than welcome to!

[@TheDJroombaGaming]

Even though i can never progress past rocketry in the base game i might just try this in a sandbox game just to say i've built it and to better understand it

[@jon4466]

I build this to spec the other day and I've encountered an issue where it seems like I can't keep the cooling area enough. The result is I get a ton of sour gas built up while the cooling area cools again. I think it's the tepizer heating the metal tiles below it when it's switched on. Even when chill enough the bottom pumps vacuum that area really fast.

[@GCFungus]

Did you start with the cooling area cold enough because if it starts too hot it will be very difficult to get cold later? The tepidizer should only be turning on when the supercoolant is around the freezing point of methane, so should not cause condensing issues.

[@jon4466]

@@GCFungus The temps of the 3 metal tiles swing from -185c to -155c.

[@commonsense-og1gz]

space materials aren't required for a sour gas boiler in general, but it makes them much simpler to construct.

[@WobblycogsUk]

Good design but I'm finding that the condensing room can't keep up at 10kg/s. I've made the change suggested to stop teleporting methane and I suspect that's the issue. I think I'm going to tunnel into the condensing room (somehow) and change a couple of sections of aquatuner pipe to be radiant. I'm wondering about going in via the turbine room and just using the liquid methane / condensing room to cool the turbine.

[@GCFungus]

It seemed to be OK when I tested it, so there may be something else that's not working perfectly. If the cooling can't keep up then either the aquetuners aren't working fully (which is probably less likely) or the heat transfer isn't enough. Are you definitely using thermium for tempshift plates, metal tiles and radiant pipes?

[@gotpwnd]

Hello, I noticed there is some NOT gate in the hot brick near the liquid tempidizer, is there any sort of automation in the hot brick or not? Thanks.

[@nico-ob6wj]

So does the airflow tile little labyrinth prevents the nat gaz from going in the wrong way and back in the heated zone? It's so intersting thank you for sharing, even if i'm not doing the exact same i'm more confident trying after seing different designs, now that I finally got thermium

[@GCFungus]

Yes it does, but the airflow tiles themselves are just there to reduce heat transfer. The actual thing that stops the natural gas going the wrong way is the bend that goes down and back up - natural gas is lighter than sour gas so I have a little catchment area so it can't flow out.

[@thelunes6549]

Is there a good way to learn the sort of calculations that go into creating these types of complex solutions in Oxygen Not Included? Perhaps it isn't as precise as I'm imagining, but it seems like the properties of a setup like this, from the temperature sensor settings to the dimensions of the setup are all very specifically tuned. Like, how the number of aquatuners determine how big the setup must be; if I were to use 3 instead of 4, there is probably a specific way I could do that without massive amounts of trial and error, is there not?

[@GCFungus]

Well the tongue in cheek answer is do an engineering degree! There is definitely some maths that go into this, and mostly around calculations to do with energy. That's derived from the flowrate x SHC x temp change. But to be honest most of the designs like this come from a lot of trial and error and building off past designs that exist in the community. Trial and error still remains the best way to design any new build, which is really a lot of the fun in the game!

[@thelunes6549]

@@GCFungus I've slogged through a biomedical informatics degree and that was more than my fill of formal education for one life lol. Those values will certainly be a great start! I just enjoy getting into the finer details of the calculations. My expertise is in data science; I try to keep spreadsheets for items and their properties with different materials. Whenever playing ONI, sometimes I come across complex problems that I'm able to find solutions for on my own, which is where the game shines most for me. Like when I managed to figure out how to use geothermal energy to create a long-term solution for a power crisis, saving my colony. There are times when I run into a huge obstacle and, rather than looking up solutions, I'd like to be able to approach them in some logical way without needing to search online. Big complex builds are cool and effective, but I dislike not understanding what I'm actually doing.

On the left where the crude drips in, I keep having overpressure issues and it breaks the far left wall, dumping petroleum out. Any ideas how to fix that?

[@GCFungus]

That shouldn't happen if the oil is immediately turning into sour gas. I would guess that you have one of two problems (or both): 1) You have some oil/petroleum sitting in the boiling area that shouldn't be there. 2) The hot side has not reached a high enough temperature yet. In either case I would suggest stopping the oil input temporarily and letting the bottom area heat up to working temperature (>700 degrees), and then start it back up. If after that the hot side keeps losing heat then you have a temperature leak issue that needs to be addressed.

[@jrharris42]

@@GCFungus that seems to be what's happening. If the steam area is at 750 when I start sending crude in, it builds up. In my case my input crude is already hot (>180C) so it should be flashing to sour gas even easier but it turns to petroleum instead. I'll check all the materials and use better insulation & things.

[@jamieharris6870]

@@jrharris42 Solved my problem. I didn't have the mesh tile under the liquid vent, and the insulated tiles surrounding it so the sour gas didn't need to go through the airflow tile to get over in to the other chamber. Also, I had too much hydrogen in the room the steam turbine is in (3kg per tile instead of 2kg). Some combination of these things was causing my cooling loop to get too cold, so the far left aquatuner was never running because the liquid was too cold when it got there. Now all four are running and the oil is flashing to gas almost instantly. :)

[@frabac72]

Quick question before I attempt this: what is the area with the super coolant and the tiepidizer for? Couldn't you just pump the methane up without passing through it?

[@GCFungus]

The tepidizer is for adding heat into the cooling loop when the sourgas incoming can't keep up. This is very important on startup as you need to heat the incoming oil and save to get rid of the cold generated. During running it stops the loop getting too cold, much like the steam turbines stop it getting too hot. With these in place the system is then fully stable and is much more reliable.

That's a good idea, and you can then feed grubgrubs from the sucrose. But if you want to grow grubfruit plants, they need an atmosphere so the cold will be an issue in that case.

[@Tamizushi]

@@GCFungus Yeah. I would argue that divergents in general are a good candidate for infinite ungroomed ranches similar to pacus. Build a 1 tile wide gap on each side of the flux-o-matic and dump every sweetle eggs on the left and every grub grub eggs on the right.

[@allenbythesea]

would be nice to get a version of this that includes the materials you used for each thing.

[@GCFungus]

I should have mentioned the key ones, and the rest simply need to be functional. So for the heating aqueutners they must be thermium, and the gas pumps at least steel. I used thermium for the heat injector door, but other than that I don't think the rest of the materials are critical as long as it doesn't melt. I did use thermium metal tiles along the bead pump and the insulation is just made from igneous rock. If there's any other materials that would help to be specified then please let me know.

[@allenbythesea]

I actually figured it out and got it running with some trial & error plus guessing and going through the comments here for adjustments. I must say, I've made several sour gas boilers both with FJ designs as well as some of my own and this is the most stable I've ever come across. Its been running for 200 cycles now with no problems which almost never happens with a SGB. Awesome design! @@GCFungus

[@GCFungus]

@allenbythesea Thanks, I'm glad it works! Stability was a key goal for the design so it's intentionally overspecc'd. By that I mean it has more heating and cooling than strictly necessary, but I also ensured it had the ability to self correct with the steam turbine and tepidizer. I got fed up of my previous design because it was very finely balanced, so when something when slightly out the whole thing broke.

[@ginsengaddict]

Is it possible to use some of the chill on the solid sulphur to cool down the sour gas?

[@GCFungus]

Yes, that should be doable to counterflow it against the sour gas, but beware that changing that may just break the whole design so it's at your own risk!

[@spychopath]

What is the purpose of the squiggle of airflow tiles at the base of the sour gas condenser? I don't get why it was designed like that.

[@GCFungus]

Fairly often the liquid methane will heat up and turn into natural gas in the condensing area. As it's lighter than sour gas, it can float back up the counterflow unless you add a bend to catch it.

[@spychopath]

@@GCFungus Thanks for the info!

[@erikwibowo8596]

hi GC, i keep ending up with some methane in the liquid tepidizer area. Will this become an issue or it is expected?

[@GCFungus]

I did notice that too on testing. I don't believe it's an issue, the only failure mode I can see is if a lot of liquid gets in there and overpressures the tiles. I think that's unlikely, but I didn't run it for a very long time. If it does keep accumulating then please let me know! I plan to implement it in my Most Dupes run too so will be able to test it for longer.

[@erikwibowo8596]

​@@GCFungus unfortunately it keeps accumulating over time albeit very slowly (i don't keep detailed track, but it does accumulate over time). I am afraid to run this now since that means eventually it will break lol. And when it does, my base would probably too reliant to the boiler to switch up to something else while repairing. I think the issue with this design is that the sour gas sometimes start to condense into liquid on the last tile of the airflow tile just before the condensation area. And by some mechanics that i don't understand, it teleports the liquid up, into the liquid tepidizer area. I'm trying out switching up the design a bit for this so i don't have to start over the build, but do please let me know if you figure something out! Oh Also, could you kindly point out on which episode on your most dupes run did you start designing sour gas boiler? I would love to see your thought process and the changes made in relation to the conditions of that particular base. Lastly, sorry for the long post, and thanks for your work!

[@GCFungus]

@@erikwibowo8596 Thanks for the feedback. I'll have to look into it in more detail at some point, and I don't understand that mechanic either. If it is the airflow tiles then it should be possible to remove one or two without affecting the design, so worth doing if that solves the problem. My other potential thought was to drop the temperature in the supercoolant area to just below methane's freezing point (say -184/-185) to freeze out that liquid, but hopefully keep the condensing area liquid. As for the most dupes run, I started layout out the first of my current 3 boilers in part 40 - but this was my old design that works but is very prone to failing as it is very finely balanced. This design I created in sandbox on my own, so don't have any footage for how I managed it. I tried lots of different ideas and a lot of fine tuning to get to this, so very much hoping we can fix this issue. Thanks for the support!

[@yehyunchoi7115]

I fixed this issue by removing the temp shift plate touching the airflow tile

[@c3n5i]

yes xou told its a late game thing, but can u shorten it down to 1 gysier as well?

[@GCFungus]

You can reduce the input, and possibly get away with a smaller design but I haven't tested with that setup.

[@arisrayden]

did i miss the automation explenation for the industrial brick or is it not part of the video? i guess the top thermo sensor is to close the liquid vent, but why and at what temperature? why are there not gates for the tepedizers? why not just use the below setting of the thermo sensors..... help i'm confused

[@GCFungus]

I covered industrial bricks in their own Tutorial Bite so I didn't explain it in full here: kzbin.info/www/bejne/g2PHeIpmirWpjas The tepidizers only go up to 85 degrees C and must be submerged to work, so the NOT gate tricks them out to avoid these limitations, as I explained in the Heating Tutorial bite: kzbin.info/www/bejne/fHiTl5ima86AmNU

[@arisrayden]

@@GCFungusmany thanks fungus, much appreciated!

[@michaeltravis7499]

Really having trouble setting up steam turbine that way, steam does not seem to heatup enough seems to be steam under 300f/150c

[@GCFungus]

Do you mean the steam in the boiler itself or in the hot brick? In the industrial brick you will need to use some form of heating to boil the polluted water, so either an aquetuner or tricked tepidizer.

[@michaeltravis7499]

@@GCFungus I figured it out I had to add atmo pressure sensor to close liquid vent for water to drain down the pipe because I had too much pressure in the room the gyser was stalled

[@BrutusAlbion]

What would I need 60kw of power for tho? 🤔

[@Sotanaht01]

10kg/s input seems like massive overkill, and 60kW output is certainly more than I could imagine needing. The problem is that this design has a massive 10kW overhead, so simply reducing the inputs would presumably create an extremely inefficient system (eg at 1/3rd capacity, 10kW to produced 20kW). So I'm kind of wondering how you would build this to operate on a less insane scale, if it's even worth doing at all.

[@GCFungus]

It's certainly possible and people have done it - there are numerous designs for 1kg or 3kg or similar. While there is some constant overhead, most of the power costs scale with the oil flow rate (particularly aquetuner power consumption), so a small design is still worthwhile. My thinking though is you may as well go big with a full pipe input, and my final design is relatively compact and good to run.

[@LoveElisaKiss]

Can this also be made in the base game?

[@GCFungus]

Yep, there is nothing specific to the DLC for this build!

[@LoveElisaKiss]

@@GCFungus good to know!

[@wattj2]

I have the DLC but generally don't play it. It seems like everything in this design is base-game compliant, except for the farming and ranching elements? So, if you were just playing the base game, how would you modify this build? It seems that the primary application for sulfur in the base game is for generating natural tiles, which by its nature doesn't require a major continuous supply. Is it feasible to modify this design to cool the Sour Gas under pressure

[@GCFungus]

That's a good point I didn't specifically mention. You are right that sulfur has no real use in the base game, so you effectively lose that food ouput and will have to use other methods (although the slickster meat is still quite a lot). I don't quite understand what you mean by cooling under pressure, as I don't see how that could be controlled or make a difference to the output.

[@wattj2]

@@GCFungus according to the wiki, if sour gas is below ~5g/cell when it condenses, it produces 100% methane and no sulfur. The information is scarce and I haven't ever gotten to the point in the game where I could experiment with this.

[@therealjoal]

Nice

[@LoveElisaKiss]

Do you have an map that I can copy? (I want to test some stuff with it first)

[@sober667]

I did sour gass boiler without thermium and supercoolant- is not preety but posible- i would not advice that However if you have supercoolant you can totaly make one using volcano as heat source - you still gonna need to adapt it so your steel gass pumps dont overheat i but its nto much harder realy - and when you get thermium you can just replace heating side

[@GCFungus]

Yeah I've seen a lot of people try sour gas boilers without space metals or with a volcano, and I just don't think it's worth it on balance other than as a challenging project. The aquetuners are needed for cooling the sour gas anyway, so I feel like you may as well use the heat to boil the oil anyway rather than using a volcano.

[@sober667]

@@GCFungus oh yeah without space materials I would rather do petroleum boiler you can cool sour gass using gass cooling hydrogen it requires some engineering again not worth only reason I did it I had disgusting amount of plastic from ranching glossy drecos and I wanted to use it

[@JasminLeblanc]

Keep making these tutorial. Dont be afraid to do simpler one for some more ovbious aspects of the game along with the more complexe ones. Tutorials for oxygen not included are sorely lacking out there. All the youtubers that make videos always end up doing very long ones (30+ minutes) and it's them talking, unscripted, unedited over them playing the game and it can sometimes take forever for them to get to the purported titled of their video. It's very annoying when you are looking for a visual answer to a question in the game and you have to sit through some guy rambling on needlessly.

[@GCFungus]

I very much intend to and thanks for the feedback. The way I've done the series is to start with the simpler/early game topics and worked my way through, so hopefully I've covered all of the obvious aspects already in existing tutorial bites - if you think there are topics missing then please let me know and I will make sure to cover, but I can't think of any myself as it stands.

[@JasminLeblanc]

@@GCFungus Off the top of my head without looking at your previous stuff, -critters, what they eat/produce and what you need to have them tamed and happy --the different biomes and the basic strategy to survive them/what you can do with 'em -the different plants and what you can do with 'em/how to grow them.

[@GCFungus]

Thanks for the feedback - fortunately I have plans for all of those topics but you are correct they aren't out as it stands. Biomes will be it's own tutorial bite in the somewhat near future, and critters & plants I intend to make their own tutorial series, so they are planned.

25 seconds in and already lost interest. Saw people doing sour gas boilers with volcanos and magma and no space materials needed so if it's just sour gas boilers in general,everyone done it and showcased it in sandbox instead of how someone can use those in a real gameplay scenario.
