Question

what is biogas? what are the main constituents of biogas? how is it obtained from cow dung? What are the use of left behind slurry?

Answer 1

Primarily consisting of methane and carbon dioxide, biogas is a combustible mixture of gases, convertible into energy. Biogas can be extracted by a biological process which converts organic material into biogas in an oxygen-deficient environment. The biomass is made up by biological residual products, seaweed and algal sludge removed from beaches as well as livestock manure from adjacent farms.

The main constituents of raw biogas is about two-thirds methane and one third carbon dioxide. They can be utilised directly as fuel in, for instance, a gas generator to generate electricity. Gas generators need cooling, a process that produces heated cooling water. A heat exchanger transfers the heat of the cooling water to water, which can be used as district heating to households and offices or for industrial production.
