Hello Edward, There is an SNV biogas project in Indonesia. The Senior Biogas Advisor is: Sundar Bajgain, Tel: +62-21-7892489/78837577 HP: +62-(0) 82112373615 e-mail: <[email protected]> http://www.snvworld.org/indonesia. He has built up good experience in Nepal and Bangladesh on biogas programmes.
1. There are arguments on how worse methane is for the atmosphere than carbon dioxide, depending on assumptions on how long it lasts in the atmosphere. Global warming is the result of radiation at different frequencies being absorbed by the different gases, preventing heat being lost from the earth. Methane absorbs more radiation from the infra-red spectrum than carbon dioxide. 2. There are two ways in which biogas can be used in engines: a dual-fuel engine uses diesel or biodiesel to provide ignition (about 20% or less). Raw biogas can be used in these engines, mixed with the air intake. A spark ignition engine can also be used with biogas, but these are more susceptible to corrosion from hydrogen sulphide, so this should be cleaned from the gas. 3. Oil cake is a good feed for a biogas plant, but should be mixed with other materials. A colleague in India has built a plant for a community that uses cattle dung and oil cake as the main feeds and works well. -- Best regards, David mailto:[email protected] Tuesday, October 16, 2012, 2:40:56 AM, you wrote: > Dear All, > I'm a beginner in bio gas, I'm Indonesian > country (south asia region), > in my country we are new for bio gas, so need > more learn about this with > all aspects, I would like to know further about the: > 1.
