Biogas scrubbers - removing the CO2 and H2S - part 1

Todays video is about scrubbing biogas, i am installing a new system, but first we must inspect and remove the old one

[@samlenlap]

for someone like me who is looking forward to make bio-gas plant there is so much to learn Thank You & KZbin keep it up looking forward to more of such videos

I can’t wait to set this up on my farm . Your filter idea is perfect.

[@glenbbqdavidson7131]

Thanks mate, really enjoy your vids

[@mjobrien69]

Didn't watch the whole video as i'm just quickly browsing and seeing whats out there for these sorts of ideas ;) Just be careful of H2S as it will kill you quicker than CO2, and yes it smells of eggs, but if its around and you don't smell eggs, that's when the ppm is a little higher, you lose your smelling sense due to the concentration and you pass out and die. Not sure how or if you are venting the H2S, but just be aware of the dangers with H2S. I'll watch the video in more detail later. The dangers of H2S are drilled into me at work for enclosed space entry on ships (tankers).

[@ShaneGorter]

Excellent video I appreciate you filming your experiment. To stack on to the safety warnings if your bleach solution becomes too acidic you're going to have a chlorine gas generator. This is what commonly kills people when they accidentally mix bleach with vinegar or ammonia.

enjoy your vlog, keep the good work

Great vid!

[@patrickd9551]

Just a small comment I didn't see around. As a means to see the actual contents of the individual filters I do like the DIY option. However for something like 15 bucks a piece you can get 10 inch waterfilter housings. Looks really clean and includes all the parts needed. You could put two mesh filters in a row, first one gets eaten, move the second to the first position and refresh the filter for the second position. Same for other filters if needed, however clay is dirt cheap and so is water, so you can just switch them out more often, but I do like the option of having the first filter be completely used up before replacing.

[@patrickquin8674]

Cool thanks mate.

[@taylorknoblock8254]

I learned to be mindful of where I put the spent steel wool after it melted the plastic bucket I put it in. Once the steel wool gets exposed to air again the oxidation reaction is exothermic. It probably would not have happened if I changed out the steel wool sooner!

[@erickc2055]

Look into adding a “liquid line filter dryer”. They are used in hvac systems to remove moisture and contamination from ac system refrigerants.

[@eastsunenergy3133]

Sure, silica gel will do that

[@glenbbqdavidson7131]

Is there any way of testing the biogas percentage as it comes out of the digester (pre filtration) opposed to it coming out of the storage bag?

[@jay90374]

Very interesting

[@Tarsan97]

Thank you Lucky for this, very interesting. I like to try something like this and have a questions; What happens if you skip all filters and scrubbers all together ?

[@faithingod9782]

I wonder if u ground up the whool stuff and made it denser if it would scrub better? And does the scrub process need to be in a certain order ? Litter, Whool then water ?

[@amathok6506]

Can you tell me what is this white gravel in th white pan that comes from the scrubber.thank you very much if you can answer.

[@briha3142]

Would filtering the bio gas through a liquid filter of all vinegar neutralize anything, on its way to the steel wool filter?

[@umeshg9107]

How do you know when to change the glass wool??

[@roxby4x490]

Hi love ur videos do u have trouble with the water not push through the 20L drum mine would rather over flow the digester then push gas through 2 inches of bleach water. Also what's ur ratio of bleach to water cheers

[@wanderleygomes7788]

saudações Brasil parabéns pelo projeto

[@jeffcameron7853]

hey mate, love your vids. Do you use chlorine in your water? Chlorine can oxidize the H2s

[@gregridgeway8790]

wow the last leg of that video was tough to watch as you suffered from the stench of the bleach. 🤣

[@ericlotze7724]

9:04 I encountered a similar thing too! I was geeking out on all sorts of commercial chemical reactors, and r a n d o m l y - p a c k e d - b e d is fancy for "tube filled with small stuff".

[@dcrook1123]

How do you dehydrate the methane once it comes out of the water?

[@RomanH1984]

Dude please be careful smelling stuff. ✌💚🖖 Hydrogen sulfide is a mucous membrane and respiratory tract irritant; pulmonary edema, which may be immediate or delayed, can occur after exposure to high concentrations.(like sniffing scrubbers) Symptoms of acute exposure include nausea, headaches, delirium, disturbed equilibrium, tremors, convulsions, and skin and eye irritation.

[@davidachee1927]

The egg smell is from the Fe2S3 breaking down at room temperature and releasing H2S. So it’s best not to smell it and put the filter material directly into some Fe2O3 powder(rust) to further process It down.

[@tomthebomb7840]

I tried to located the see through filtration canisters on Ebay and had no luck. Can you advise that name or manufacturer. Thanks

[@davidoutdoors74]

How’s your digesters doing

[@1Bhishu]

Out of curiosity, what happens if you use granular salt to extract moisture 🤷🏿‍♂️

[@semihtolgahaydaroglu7618]

weight of hydrogen sulfide sinks to the bottom compared to other gases.co2 gas stays above other lighter gases.The last gas to come out is hydrogen sulfur.You can also turn carbon dioxide into a by-product with sodium hydroxide. Carbonate is beneficial for plants.sodium hydroxide directly absorbs carbon dioxide. It neutralizes it and carbonate is formed.

[@davidoutdoors74]

Yes to biogas

[@mannatuu]

Not sure what continent you are on / As this makes a difference . I am looking to experiment with one in the UK.

[@mahamedabdilahi3762]

Please helpe me why a lpg is filtering

[@mortarriding3913]

What can be done to dispose of the various filter materials safely once they're expired?

[@davidachee1927]

The steel wool filter should be safe to chuck in the trash as iron sulfide( the end product) is not water soluble and is only mildly toxic if ingested. Check with your local waste peoples but in these amounts it should be considered ok to chuck it in the bin.

[@oddzc]

You should sell plans to build a system like this.

[@javierdomenech4370]

Hi I made a bio digester on a water tote 250 gallons I compressed the bio gas I didn't make a filter and the flame is blue and yellow orange could it be contaminated thanks help

[@tinoohove7611]

A yellow flame shows contamination. Pure biogas burns with a pure blue flame

[@madalitsodaviemasina6271]

After purification, approximately how much gas is lost???

[@toon1760]

what material are your tanks made of ? I'm a welder and I'd like to make a biodigester but in metal, would that work ?

[@98Luthfi]

should have coating inside your tank, i think?

[@masumbilla5996]

Where u are?please want to trining

[@iwontbebeat7111]

You can re-use that clay for cat litter ...lol 😂

[@prabhanjanpatil5062]

Hey...have you tested for the concentration of gases present after the purification

[@danieltaurins86]

Testing costs a lot here in aus, I’d like to but yer, it burns, that’s enough for me being domestic

[@mundu2000]

H2S + 2NaOH → Na2S + 2H2O, is this the correct formula? I enjoy your videos by the way

[@elfablo1]

comment vous joindre

[@umeshg9107]

When and how do you recharge the clay palletz

[@LazarusMastiffs]

If they get clumpy or damp, replace or dry it and put it back.

[@akashalam1810]

i want to made this kind of bio gas plant, can you help me.....

[@ArktourosUltorMaximus7600]

However, do keep some of the h2s inside the purified methane. Not much, but the H2S can act as a smell indicator incase the tank leaks, much like tert butylliol is used in LPG leak indication.

[@thenewintheworld3285]

Hi,how are you,,, how i can content you ?please !!

[@briha3142]

Maybe charcoal, the kind used for fish tanks/aquarium filters, can clean the smell out of the gas mixture in lieu of the clay/kitty litter? Or maybe even charcoal briquettes broken up?

[@LazarusMastiffs]

The clay is more for drying than smell absorption.

[@jeetender123]

Hello Sir, what's the name of the solution which removes CO2 ? I didn't get it clear from the video.

[@vasaoz]

its water and bleach, but i would not suggest it if you are not changing it like every other month or so. just use water.

[@davidoutdoors74]

My digesters are cranking

[@abiogaz]

Dzień dobry.

[@danieltaurins86]

dzień dobry przyjacielu, dziękuję za oglądanie

[@abiogaz]

@@danieltaurins86 to ja dziękuję za ogrom wiedzy jaki Pan daje w swoich filmach. Będę robił płuczkę wodną ale boje się sody kaustycznej, zamiast tego chce zrobić roztwór soli kuchennej z popiołem i wodą, czy zda to egzamin?

[@dogwithlaserpointer]

Anybody else cringe as soon as he started smelling things? H2S is deadly, just opening the system like that made me cringe.

[@T2Exile]

just a bunch of talking. just get to the point!!
