Bio Fuel Storage: Building A Gasometer

In this video I build a wood gas storage device that cleans and pressurizes the gas all in one! Thanks to my sponsor Squarespace you can make a great website easily! Check them out at: www.squarespace.com/nighthawk
In case you missed it, here's my last video where I built the gassifier used in this video to make my gas: • Testing A Better Wood ...
The wikipedia page on gas holders has some great visualizations and images of commercial gasometers: en.wikipedia.org/wiki/Gas_holder
Thanks to all my Patrons for helping me make these videos! A special thanks to my top Patrons: Syniurge, Matthew Leitzke, TheBackyardScientist, Enzo Breda Lee, John Johnson, & Thibaud Peverelli! / nighthawkprojects
So what is wood gas good for? A lot of you have asked that question. The main point of wood gas is to turn a renewable fuel like wood/plant matter into a form that is compatible to be burned by modern technology like cars, generators, stoves, etc.. Wood gas is a fuel that can be made by anyone with simple equipment, and can run a gasoline engine with only minor modifications. The process I use in this video to make it produces a very clean result, but is not the most efficient way to make large quantities of gas for immediate burning. I'll be demonstrating other methods of wood gas production in future videos.
Thanks for watching!

[@danielpiotrowski1681]

Who would miss one of your videos?

[@Nighthawkinlight]

To bubble the water from the bottom to the top means that the gas needs to have enough pressure to force the water out of the tube. That's more pressure than my gassifier generates in this setup.

[@unusualfabrication9937]

silicone rubber is a thermal set, so it is pretty heat resistant

[@fatihduran2110]

I think a shower head hose might be able to survive the heat better.

[@walkingdead171]

You should make an airtight crockpot to heat the wood inside, leading to a canister to store the gas. Something I found online: Higher temperatures improve hydrogen yield in the gaseous product while CO yield decreases. Under nitrogen atmosphere, after 2 s at 950 °C, 76% (daf) of the mass of wood is recovered as gases: CO, CO2, H2, CH4, C2H2, C2H4 and H2O. Tests performed under steam partial pressure showed that hydrogen production is slightly enhanced.

[@AussieChemist]

Instead worrying about what type of tube you use , you could use a condenser to cool the gas before it reaches the tube

[@robertwjenkins6916]

I was thinking almost the same thing...just use a cooling system on the pipe and hose like the worm in a still

[@Solnoric]

And condense out tar that blocks it all up.

[@kbee225]

I'd say just run it though a water column. It'll cool the gas and also remove the impurities.

[@stanwashighski3553]

Absolutely correct! Coil condenser with a collection pot to capture contaminates at the bottom works very efficiently. I've used this method for years to convert acetone to diketene with great success.

[@marshallscreekfarm3833]

Isn't the condensed liquid diesel? so a diesel collector in the middle will prevent condensation in the pipe and melting the pipe.

@@MrRasZeein medieval times people had dedicated parts of their forest for firewood, idk how it’s called in English but in Dutch it’s called “kreupelhout”. They had fast growing trees that they kept short and guided into growing many sidebranches, these could then be harvested yearly for firewood in the winter, and then next year the tree had made new branches that could he harvested. Saved people a lot of trouble, as they where usually close to the farmstead/village and no need to end the lives of trees just to get firewood.

[@USWaterRockets]

Get some PTFE tubing. It's the most temperature resistant material that's flexible. You need specific connectors for it, but it will work up to 500F.

[@Nighthawkinlight]

Great tip!

[@flavioleo1055]

Or lab rubber tubing, a lot cheaper, from amazon or eBay is easy to find

[@sparkyprojects]

Silicone tubing would work You could put the inlet into the bottom tank, but you still need a small amount of flexibility A gasometer normally has 3 walls, the middle one being the top, the cavity is normally filled with oil iirc If you fill the main chamber with water initially, then when you get sufficient gas you could drain main chamber (bottom inlet would help with this), that would give you more room for gas, and lighter to carry

[@SianaGearz]

PTFE is not THAT flexible and not THAT temperature resistant, it starts to slowly give up around 250°C. Silicone beats PTFE on both accounts.

[@USWaterRockets]

PTFE is perfectly flexible and suitable for the application shown in this video. It will hold significantly more pressure as a result of the increased stiffness, which could prove useful if weight is added to the gasometer to compress the wood gas. Additionally, the melting point of PTFE is 327 degrees C compared to the lower 300 degrees C of silicone rubber. Either one is better than the vinyl(?) tube in the video.

Silicone tubing is good to have around. It's short term temperature resistant to well over 300°C, long term to about 200. It won't melt ever, and if it starts to discolour, it's degrading or basically slowly burning up. Vinyl has a fairly high melting temperature... i forget... but it's a very hard plastic, so tubing must contain plastifier, which potentially has little effect on melting temperature but gets glass transition temperature way down. Incidentally this is why it's becoming softer when it heats up. At the start of the video i guessed that it would survive and hey happy that it did.

[@Gagy]

I'm loving these wood gas videos! keep em coming!

[@Kineth1]

I really liked this video! You can get around the flexible tube by having your inlet and outlet pipes enter the BOTTOM of the water chamber, and then rise through the water into the headspace of the floating chamber. Gas will come in the bottom, rise through the tube in the water (or you could have it bubble through the water, but your gas generator would have to be above the water line) then it would either float the upper chamber, or pass out through the outlet pipe (depending on gas demand). This is the first wood gassifier that i have seen with any type of accumulator, and I must say, it has given me a lot of ideas!

I like how you can see the gas flow through the vinyl pipe, but I think a insulated hose like the type that goes from the water source to the toilet might work better and be easy to retrofit in your application. Great job!

[@akashmukherjee2405]

7:05 the condensation is a mixture of wood alcohol (methanol), gasoline, tar and diesel. All of them are also valuable. You can set multiple filtration setups to collect them as well.

[@sharpjk]

how would you separate the four...also is the water in the gasometer tainted in anyway?

[@Snix121]

Fractional distillation

[@BenjaminVestergaard]

Could actually be harvested with some water-cooling of the pipes, perhaps a spiral chamber with an outlet, then the gas passed on to the gasometer will also be purer but of course also denser, so perhaps you'd need a spring or something to lower the pressure in there, basically sucking the gas in.

[@Hellsong89]

Tube with in and out connection, cooled by water, so it condensates to pipe surface and collects on the bottom as a pool, witch can then be with regulated flow valve let empty to container. Separation would be using standard oil industry techniques of fractional distillation as it was mentioned, where start product is heated and released to chamber. Due lack of oxygen it wont burn, but turn into gas. Chamber has several different levels with different levels of heat. Gasoline or methanol is easiest to turn to gas and will float on top chamber, where as heavier oils that take more temperature to turn into gas will condensate on lower levels, where these can be collected to separate containers, filtered again and put on use.

[@gazzarrr666]

I would consider 'cracking' the distillate while it's still a avpour by heating further over some kind of catalyst. That way you will get more gas from the liquid portion, so more yield of usable gas.

[@GadgetPonyGal]

It's really awesome seeing you doing so much experimenting with wood gas. Like I said last time, try using ordinary trash, like paper, cardboard, cereal boxes, old rags, etc. as production fuel at some point. It may be a bit harder to use with your current setup, but I think it would be worth it to see how much gas you could produce from it compared to regular wood. And on that subject, it might be interesting to see how much you get from fresh wood compared to dead and dry wood. Also, bringing your adorable bird in to give us incentive to watch the sponsor bit of your videos is really clever, and I don't regret watching it one bit. I'd love to see an off-topic video just about your bird at some point. It's super cute, and it looks like you take very good care of it. ♥

[@alaric_]

I think the amount of wood gas produced is equal in fresh or dry wood, if the wood is otherwise the same. The potential for gas produced is not ruled by freshness, it just means it has more water. At least that's what i have always thought. Before the wood will pyrolyze and gasses will exit the wood material, water has to dissipate from it and that takes time and energy so the process is just slower. That could actually be a test in itself; how much dryness affects before the wood gas starts to produce.

[@motormaker]

If you run your gas line in the bottom it can bubble up through the water to help clean the wood gas. It would also leave the top of the moveable sleeve unobstructed. In the late 80s or early 90s I saw an article in Mother Earth News. A farmer was running a methane digester with manure. He was using a similar gas collection device only massive. It was so big it had a pulley and counter weight system to make the inner bell neutrality buoyant. I believe his outer tank was concrete. I seem to recall it was as big around as a silo. With a system like that you could change the counter weight as a way to adjust the gas pressure.

[@scottscontracting]

Thank you for the heads up on the wood gas storage.

[@abcstardust]

[@rockingupthewrongtre]

You could put in a dirt pocket or drip leg (used in the piping trades) to collect the tar as it goes through the tube, then you could just blow off the tar and condensate to keep that tube from getting clogged over time!

[@dalsio]

Braided steel cables (the ones meant for hot water hookups) or PEX (polyethylene cross link) tubing can't handle combustion temperatures but they are at least more heat resistant than vinyl and should have common links with standard plumbing fittings.

Those experiments are awesome, and I can't wait to see what will happen in the future, indeed 😍 About tubing, I know there are some kind of silicone pipes which are capable of dealing with some high temperature (up to around 300ish C, which is about 500ish F), so you should be able to find something (but I see also a lot of comments in that sense): but I live in Italy so I can't tell for sure where to find those things in USA (except something like ebay, amazon or similar) More than that, have you considered putting a longer piece of tubing (like 4-5mt/12-15ft) which a part is submerged in some cold water? This might help both with condensation and lowering the overall temperature of the outgoing gases.

[@Nighthawkinlight]

Make sure that you separate the gasses and store them in separate containers. Storing oxyhydrogen together in a tank like this would be an explosion waiting to happen.

[@vcokltfre]

There are a few videos on youtube where people explain how people died because of compressed oxyhydrogen being so volatile and exploding

[@Freizeitflugsphaere]

NightHawkInLight Of course I know that, and I already made a lots of experiences with oxyhydrogen in the past. Storing about 5 liters is really no problem, its not that huge explosion, compared to other explosives. Seperating the gases using gravity works a little bit and reduces the amount of oxygen in the mixture, however, there is still enough left for a slow combustion. So I am going to find another way of doing it🤔☺️

[@James02876]

Freizeitflugsphäre it's pretty easy to separate the two gases if you're generating it through electrolysis. You use a wide basin of solution, and use separate catchment containers above the anode and cathode. You can even use two separate containers if you have a solution-filled tube connecting them. The hydrogen reservoir will need to be twice the volume of the oxygen one.

[@JustinTopp]

Dear NightHawkInLight, I have come up with a few cool things you could make a video on using wood gas. 1. Compress cleaned gas into a tank and use it in a grill or gas lantern. 2. You could run a small generator off of it and/or see how big of a generator it can power. 3. Make oil and purify it into gasoline/ diesel fuel. 4. Run a propane fridge off of the gas 5. It would be more work but a go kart running off wood gas would be cool. It could use compressed gas.

[@ellenorbjornsdottir1166]

I don't think a propane fridge will work. Any stove will though with an appropriate jet.

[@3karus]

If you want fixed metal pipes you could just install a thin U shaped metal tube that goes down trough the water and up above it. It's essentially filling the tank from the inside, not trough a valve.

[@rfldss89]

I'm not sure how well that would work, since the pressure from the wood gas production would have to push the water out of the U shaped tube.

[@Electroblud]

@Rafael Dos Santos That's what it is doing with the current setup too. So it should be fine. I'd go with the internal tube.

[@3karus]

Rafael has a valid point. A long Tube surrounded by water will pretty much act as a condensator and collect moisture from the wood, just like the PVC tubing, but worse. Attaching a small reservouir at the bottom would solve that problem easily and with no big effort.

[@TheCommentAcc]

I work with systems that measure exhaust gases from combustion engines. Those gases are hot and need to be kept at temperature to avoid condensation. To keep the gases heated we use so called flexible heated lines which use PTFE or PFA tubing inside, PFA being more chemically resistant (as far as I know). As you don't need to keep the gas heated, the tubing itself should be sufficient. It's not as flexible as vinyl tubing, but I'm confident you can figure something out.

[@SundownMarkTwo]

NightCaiqueInLight Bingo, new subchannel name for bird antics.

[@LoneWolfsVoice]

I know this was part of my suggestion on the last video and apologize for the repeat. If you add a copper coil and an intermediate collection can right after the coil but before the tubing you will cool the gas significantly before it hits your tubing thus increasing its life span and you get the added benefit of collecting the condensate before it hits the storage container. Similar to how alcohol is condensed in a still.

[@IonutJaR]

cooper and brass can be considered as catalyst as well and purify the gas

[@johnjulie6657]

But the tar by-product would condense and cool within the condenser coils, whereby clogging the system and eventually causing a back pressure into the gasifier can... please tell if I have this wrong?

@@johnjulie6657 a very low tech way of fixing that is putting a longer outlet pipe from the furnace. And taking a cue from natural gas piping place a T fitting with a pipe going down.

[@joelnobles1682]

Thanks for your time. I enjoyed your video.

[@flash001USA]

The gas will self clean with or without water. I build gasifiers and I use a design that I came up with that I call a expansion tank that works on the same theory as air conditioning and Refrigeration where you have gas passing through a small tube into a large chamber where it cools down due to the expansion of the woodgas and while it's cooling down it's losing humidity in the gas along with other contaminants that will flow to the bottom of the expansion chamber. I also use a traditional method a passing it through filter media but I use a tri-filter setup to further capture water and humidity along with other contaminants in the gas. What you built works really well especially for a demonstration but it would be impractical for running an engine because you'll need a larger volume of steady wood gas for power production even for a home setup. You made a really good demo video. Thanks for the Post

[@piranha031091]

Maybe you could add a three way connector with a collection vessel to recover the liquid that condenses out of the wood gas? It's going to be mostly water at first, but should also contain a variety of hydrocarbons and aromatic compounds (wood-tar creosote). These having low miscibility with water, they should separate and could in principle be easily recovered. Creosote is a cool substance, with some interesting uses, like treatment of wood.

The brown liquid can be fractionally distilled to recover the methanol in it.

It would be a great idea to compress all of collected and filtered gas with an old refrigerator compressor or a modified bike pump (I've seen people making pumps out of pvc pipe that are able to produce more than 100psi) into some pressurised container for later use. Your low pressure container is great for collecting gas before it could be compressed

[@tedf2]

Compression rates are not good. I had the same thought. I found that a propane tank would only get a car 2 miles on the road.

@@ellenorbjornsdottir1166 I'm not sure what you're asking. But form the various websites describing vehicles running of wood gas it seems that the production of the gas was produced on sight directly feeding the engine. Also, the efficiency was equivalent to gasoline efficient vehicles, including transportation of the wood fuel. p.s. I'm no expert on this subject, although I'm indentured by it. Having said that, I don't think this is an alternative as a replacement of the gasoline engine i.e. "The Green Deal." There's just not enough of the feed stock around, just like ethanol. There are some plants worldwide operating on this fuel because they have a feed stock of waste from the products they harvest. Also FEMA has designs for producing wood gas for generators. but it's not meant as a replacement of the electric grid, rather it's to compliment it during emergencies when the grid is down.

as I watched this I was applauding your accomplishment, FanDernTastic, this vid was worth the time to watch several times

[@jaytate7899]

Oh thank you I was disappointed I never found a video on how to store it I’m glad you made a video

Not sure on other tubing you could use but if you extended the metal pipe after the 90 degree bend it will move your current pipe further from the fire and also let some of the heat the metal conducts to dissipate as well. Maybe extend it close to a foot but I figure any distance will help the further the better. Also what about letting a damp rag lay on the pipe for even more cooling would also help i would think

[@TrollFaceTheMan]

5:18, the tube I would suggest using would be 100% Silicon. It should be rated for at least 450 F vs Vinyl Tube's 150-175ish F. It's also non porous so in theory it should be easier to clean all the soot buildup off of too. Oh and it's very flexible.

[@rileymcdowell2889]

TrollFaceTheMan could he also use some metal braided lines? He could probably get some at an auto parts store

[@TrollFaceTheMan]

Riley McDowell, good question there are two big factors I would consider with that. The first being because they are opaque it would be much harder to tell what is going on inside them so visual assessment of gas production would be impossible for the tubing. The other concern I'd have is though many are made to be rust resistant would the heat or even the byproducts like soot, methanol or things like potassium/sodium/calcium carbonate that accumulate over time in the tube affect that?

[@IaCthulhuFthagn]

Polymer tubing for laboratory glassware use, Tygon for instance, might be pretty good contenders as well, if a little more expensive, assuming one can strike a good balance between flexibility and resistance to heat and chemical attack.

[@jimrojas62]

Nice job. I will try this on my next build.

[@maderightamerica3216]

Thanks for the video. I learned a lot. I am going to see what your sponsor has to offer. I hope they have a communication system to see and hear the customer. Look forward to your next video. Take care my friend.

[@jason-ge5nr]

Super cool. I think the black fuel line would take the heat all day long

[@laharl2k]

vinyl tube can easily stand the heat. It softens but wont melt and can easily do 300ºC without burning. If its not smoking/smelling and getting brown then its ok.

[@juliusruchhoeft1967]

Nice video. Good job. It would be great ich you could turn this gas with the fisher tropsch synthese into liquid hydrocarbons. As a catalysyst i would take cobalt because it wont oxydise like iron. The reaction also works on 1 bar. You also need a temparatur from 150-300 degrees Celsius. You wil get mostly methan and a few hydrocarbons. The gas should be cleaned before use. Sorry for for the mistakes in the text. I have got english at school for about two years

This is fascinating and I'm glad you made the vid. keep it up! :)

[@somebody4217]

I'm very impressed. Bravo!

[@DomingosMultichannel]

i could say that every video from you. irealy like your kindness and your passion to your work. i can see, when you are burning your fuel that that is a true succses to you. Please go on with your work - it deliveres a great message like styropyros videos for example, that learning - especially learning by doing is a good way of expanding our knowledge. are you planing to pressurise it until its liquefaction and fill it up in cans?

[@pierreuntel1970]

I think you can use a coil of copper pipe to cooling off the gas a little before it enter the plastic pipe? That way the gas will not too hot to melt the tube
