Currently working on an article about Biogas storage: I'm writing about - Floating drum- Biogas bags- Compressed bottles

Anything else?

• • Dominic Kahumbu Wanjihia Mini grids. Loooong large diameter - min 6" distribution pipe under medium pressure - 150 psi max. The pipe is the holder. There can be many feed - in pointsGefällt mir · Antworten · 18. September um 22:45
  • Nick Chase Dominic, thank you! I have to check on them. Have you ever used a mini grid?Gefällt mir · Antworten · 18. September um 22:50
  • Dominic Kahumbu Wanjihia Mini mini mini grid, yeah . Multiple feed in's - 6, and multiple users - 4This is basically how our demo site has been setup for the longest time.Gefällt mir nicht mehr · Antworten · 1 · 18. September um 22:54
  • Gene Febus 6inch pvc pipe? Sounds expensive. What about a fifty gallon barrel? Has anyone tried pressuring one up? Thanks for all the info Nick . I'm from a region in Washington state (eastern) there is a lot of fruit grown here. Many dairies too. The local water...Mehr anzeigenGefällt mir nicht mehr · Antworten · 2 · 18. September um 23:36
  • Jason Beers The Bozeman, Montana water treatment facility, pre expansion, created over 100,000 cuft of methane daily. They used 60,000 cuft in the process and burned off 40,000 cuft......DAILY!!! We should be putting this in the grid to heat houses.Gefällt mir nicht mehr · Antworten · 2 · 19. September um 02:17
  • John Stewart most states have laws against distributing the biogas from their digestors... petroleum companies keep the competition in checkGefällt mir · Antworten · 1 · 19. September um 14:34
  • Thomas Gram I've been wondering about using sorbents for biogas. Some say that might be the next big thing in the fossil gas industry.Gefällt mir · Antworten · 22. September um 05:44
  • Nick Chase sorbents? for storing it? wouldn't it take more space at the end?Gefällt mir · Antworten · 22. September um 15:30
  • Dominic Kahumbu Wanjihia Gene Febus no not a 6" pipe. I mean 6 digesters feeding into a minigrid with 4 users tapping off. The piping from the digesters are 1/2" HDPE to a 4" PVC buffer manafold, then 3/4" HDPE to the points of use. One of the user's is about 100m from the manafold and doesn't need a pump Gefällt mir · Antworten · 22. September um 18:07 · Bearbeitet
  • Dominic Kahumbu Wanjihia Nick I think Thomas is talking about sorbents as a feed stock. I'm not sure of there are any that have any really high energy value. Correct me if I'm wrong but sorbents are like sponges. So they're really just full of water. So I don't see the real advantage. Maybe they grow / multiply real fast? Thomas?Gefällt mir · Antworten · 22. September um 18:13
  • Gene Febus Oh, I get it. Storage capacity is separate from the grid.Gefällt mir · Antworten · 1 · 22. September um 18:14
  • Thomas Gram No, I was talking about sorbent storage. My understanding is that something like activated charcoal can form intermolecular bonds with methane and hold it at a higher density without exceeding atmospheric pressure and without dropping the temperature. It's supposed to take up less space than a room temp, standard pressure gas bag.Gefällt mir nicht mehr · Antworten · 1 · 22. September um 18:18
  • Dominic Kahumbu Wanjihia Isn't that adsorption using activated carbon? ... and is kinda complicated. From my understanding, the process uses 25 - 30 % of the gas energy value to compress in the first place, then another 20% to back-wash the activated carbon. Far too complicated for my liking Gefällt mir · Antworten · 1 · 22. September um 18:29 · Bearbeitet
  • Gene Febus That would work well for vehicles powered by gas. Seems like. I'm very interested in storage. Hence the fifty gallon drum query. I have probably 30 or more poly drums sitting around and about 100 pigs. I am confident I can make alot of gas but what if I have too much? What do you do with it?Gefällt mir nicht mehr · Antworten · 1 · 22. September um 18:30
