[Digestion] Safe Transportation of Low Pressure Biomethane for Social Gatherings

Tue Jun 10 01:49:27 CDT 2014

We have designed biogas pipelines to separate digesters from the CHP plant to put the heat closer to the end-user. These are low pressure PVC lines and no big deal.  Condensation is the biggest issue and a means to remove water from the line has to be included. Short distance transport, probably no problem.

Removal of anything beyond corrosive compounds is not necessary for most combustion uses of biogas …only feed in to the natural gas grid with the specifications they locally require will necessitate CO2 removal (which is way too expensive for most jurisdictions support systems).

Hi All,

The folk related to biogas to biomethane is not totally storied. We have invested a lot in engineering integrated "wet columns" for both  H2S treatment (bio trapping) and "water lines" for CO2 scrubbing (greenhouses and algal cultivation) in ordre to generate additionnal revenues which will compensate the low  financial costs and few running costs of these treatment equipments. A pilot plant is under-way  and we shall thereby verify (or not) that the positive perspectives of our economic model are more than virtual.
Let me just say that considering the dramatic increase in demands of biopesticids and specific fast growing energetic or feedstock biomass there is a ground to develop such technologies. Some practical answers in the forthcoming months, regarding biogas treatment thus opening more ways to biomethane uses and transportation.
Cheers

I agree with Kyle. We also make biogas bladders for transport, and you could but about two + hours of cooking gas is a relatively small space.  The gas flows out really well with just a small counter weight.  

I also think the effort to scrub the gas will be too expensive and too much effort for the overall gain.  Finally, competing with US natural gas would be really hard as it is some of the cheapest energy in the world.  Rural households outside of that grid may be interested.  

Good luck, and keep us posted.

Hi Jacob, 

Sounds interesting! I hope the economics work out in the US though. In Kenya we have the advantage that we can sell our biogas for about 4 times the price of natural gas in the US, kJ per kJ.

We have a supplier called Q-energy, based in Uganda, manufacturing in China that makes small bags that are meant for transporting gas. I would talk with them. I don't see much trouble in getting the gas out, we just put a piece of plywood  and rock on top of a bag and all of the gas comes out

But why do you want to scrub it? Sounds like a lot of work for not much benefit. Maybe I am missing something.

Best wishes,

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,
