Question

by which process biogas is obtained​

Answer 1

Answer:

anaerobic digestion

Biogas is produced when bacteria digest organic matter (biomass) in the absence of oxygen. This process is called anaerobic digestion. It occurs naturally anywhere from the within the digestive system to the depth of effluent ponds and can be reproduced artificially in engineered containers called digesters.

Answer 2

Answer:

process biogas is obtained​;

Explanation:

Biogas is a renewable energy source made possible by the anaerobic decomposition of organic waste by specific microorganisms. Methane, hydrogen, and carbon dioxide are all present in it. Agricultural waste, food waste, animal dung, manure, and sewage can all produce it. Anaerobic digestion is another name for the process of producing biogas.

Biogas naturally recycles waste items and turns them to useful energy, minimising pollution from trash in landfills and reducing the impact of hazardous chemicals emitted by sewage treatment plants.

Biogas turns the hazardous methane gas produced during decomposition, into less harmful carbon dioxide gas. The organic substance decomposes only in a damp atmosphere. Organic debris or garbage dissolves in water and generates a nutrient-rich sludge that can be utilised as fertiliser.

Biogas Plant Biogas is produced in anaerobic digesters, which are referred to as Biogas plants.

There are five parts to this:

The slurry is fed through an intake.

The fermentation chamber, which produces biogas through the action of microorganisms.

The gas storage tank, which will be used to store the gas produced.

The slurry's used slurry outflow,

The gas produced is removed through the exit pipe.

Organic matter is fed into digesters that are entirely submerged in water, creating an anaerobic environment. Anaerobic digesters are the name given to these types of digesters. Microorganisms decompose organic waste and convert it to biogas.

The biogas is then sent to the appropriate locations via the exit pipes.

Organic matter decomposition

The first stage involves the degradation of organic polymers like carbohydrates, making them available to the acidogenic bacteria, which are the next stage of bacteria.

The sugar and amino acids are subsequently converted to carbon dioxide, ammonia, hydrogen, and organic acids by acidogenic bacteria.

Acetic acid, hydrogen, ammonia, and carbon dioxide are now formed from the organic acids.

Methanogens convert them to methane and carbon dioxide at the end of the process.
