Dear All,
I joined this group newly. I have seen some interesting discussion
in archieves of August on "Electricity from Biogas". Presently the use
of bio gas for domestic cooking is limited to houses in villages who
have cattle in their vicinity. Since methane is the only burining
component in biogas, i believe enriched biogas with higher methane
content can be bottled in cylinders for domestic cooking.
I have done some survey in this area. Researchers in IIT-delhi have
done some research in purifying biogas and bottling them into CNG
cylinders. I am giving the reference below.
"Biogas Purification and Bottling into CNG Cylinders: Producing Bio-
CNG from Biomass for Rural Automotive Applications"

They have transferred the knowledge to "Indian Compressors Ltd" in
delhi. Biogas is compressed in these cylinders at a very high pressure
and they cannot be used for domestic cooking.
Here they are enriching biogas by removing CO2, H2S etc. Finally the
methane content will be around 98%. Since we already have the
technology for storing this enriched biogas at a very high pressure as
CNG cylinders, I believe it should be possible to compress enriched
biogas at medium pressure for domestic cooking.
Please let me know if anybody in this group is aware of "bottling
biogas for dometic cooking". Please give me pointers to research in
this area and information about companies involved in this area.
Thanks,
Praveen.
