Question

describe the process of biogas formation in biogas plant.

Answer 1

Answer:

The biogas plant receives all kinds of organic waste - typically livestock manure and organic industrial waste. The dry solid in livestock manure contains carbon, among other things, and in the process this carbon is transformed into biogas, a compound of methane (CH4) and carbon dioxide (CO2).

The manure and waste are mixed in the plant's receiving tank before being heated to 38-52°C/100-125.6°F and pumped into the digester in which the biogas is produced. The biomass stays in the digester for 2-3 weeks and the fermented slurry can subsequently be used as crop fertilizer. This fertilizer has improved qualities such as less odourinconveniences when spreading the slurry and significant reduction of green house gasses.  

Answer 2

• Biomass is turned into gas by microbes  .In the biogas reactor, microbial action begins and the biomass enters a gradual process of fermentation. In practice this means that microbes feed on the organic matter, such as proteins, carbohydrates and lipids, and their digestion turns these into methane and carbon dioxide.
