[Digestion] Digestion Digest, Vol 45, Issue 4

Sun Jun 8 21:46:37 CDT 2014

Jacob and listers,
Doing research on biogas systems in x the USA is very different doing it 
from India. There are regulations in the USA about compressing and 
transporting gas that do not exist in India. I have been doing work in the 
UK, but trhere are so many restrictions that I think that I need to do work 
in India, if I am to achieve the results I want. I am working with an 
Indian NGO, SKG Sangha, and we are hoping to do more research. We have 
built a system to process food wastes for a big hospital complex in South 
India, so we can test some of these ideas.
Best wishes,
Dr David FulfordKingdom Bioenergy Ltd

Dr. Karve,
Thank you for your response! (It is really great to hear from you, my whole 
team and I really admire the work that you are doing.)
Transportation via a cylinder does make a lot more sense. 

Now I am wondering what other kinds of pumps could be used to achieve a 
high pressure for storage. 
I do know of some Chinese-made biogas pumps that achieve around 4 psi, I'm 
wondering if that would be enough for a cook-out and if a more powerful 
compressor that I don't know about yet would be able to achieve a higher 
pressure (and thus store more gas).

Do you have any suggestions of pumps that can pressurize biogas safely 
(besides a pesticide pump)?
Sincerely,

Dear all,

I am a researcher and entrepreneur at Carnegie Mellon University and I am

working on how to share the knowledge and benefits of simple AD systems

with Americans.

My team has been investigating the possibility of converting commercial

food waste to biogas in a low-tech 250 gallon digester, and then scrubbing

that biogas ourselves into biomethane.

We want to hold events or cook-outs where local chefs could cook great 
food

using biomethane.

To do this in our area the best way to share this biomethane with others 
is

to drive it to a local gathering.

What do you all think the safest way to go about transporting this

biomethane on the road would be? If we were to invest in a low-cost biogas

inflatable (ie. PVC) and house this bag inside of a large plastic 
enclosure

would this be relatively safe?

We want to share this technology and its benefits with others!

Can you help us figure this problem out?

Best wishes,

-- Jake Douenias

Dear Jake,

 One can fill non-pressurised pure methane into inflatable bags and

transport it, but in this form you have to cary large volumes of it.

Secondly, you would have to use pressure for getting the methane from

the bag into your cookstoves. It would be easier If you could use

pressure at the facility where you produced the methane, and filled it

into rigid cylinders. Not only would the volume be reduced but the gas

would flow easily from the cylinder into the burners of the stove. We

have tested this concept as an experiment, using LPG cylinders as

containers and a pesticide pump for filling the cylinders.

Yours

A.D.Karve
