A CASE STUDY TO PURIFY BIOGAS USING SIMPLE WATER SCRUBBING METHOD AS SOURCE OF ENERGY FOR RURAL DEVELOPMENT IN INDIA

摘要

The supply of petroleum fuels will gradually decrease and these will have to be replaced by other sustainable fuels. Natural gas is a fossil fuel that has many advantages as compared to liquid fuels like diesel and gasoline and has also been pointed out as a major alternative in the change over to sustainable fuels. Upgraded biogas has the same advantages as natural gas, which additionally is a sustainable fuel that can be manufactured from local waste streams thereby also solving local waste disposal problems. Biogas is a clean environment friendly fuel. This work presents an experimental study of purification of a biogas to improve its quality by scrubbing the carbon dioxide (CO_2) and hydrogen sulphide (H_2S) contents. The results obtained are possible to deliver a biogas which is upgraded to natural gas quality for direct use as a vehicle fuel. By using local resources, which are available at agriculture fields, experimental set-up was developed. This set-up is simple for fabrication and operation by keeping low production and operation cost. The results obtained are encouraging and will make one of the options to use water scrubbing method on field side to upgrade the biogas as non-conventional energy source for direct use as a cleaner fuel for engines.
