Question

Write down the process of gas production by biogas plant

Answer 1

Answer:

Biogas or gobar gas is a combustible gas.

It is produced through the anaerobic breakdown of waste biomass.

The biogas plant consists of the following parts:-

1) Inlet or charge pit:- for passage of slurry into the digester.

The raw material used is cattle dung, farm refuse, organic waste.

2) Digester:- cylindrical tank which is airtight, above which is present a floating gas holder of metal with an outlet of gas and pit for removal of sludge.

Here the organic wastes get solubilized into simpler substances called monomers (solubilisation).

Monomers change to organic acid by fermenting microbes (acidogenesis).

Organic acid mostly formed is acetic acid.
