How to Convert Raw Biogas Into Natural Gas

Biogas is a mixture of methane, ethane, and carbon dioxide that is produced by the decay of organic matter. Biogas has many applications outside of its original purpose as fuel for cooking and heating homes as well. If you are considering converting raw biogas into natural gas or a method of removal of hydrogen sulfide from natural gas, this is the article to start reading.

Biogas was first discovered by Carl von Linde in the late 1800s, who was trying to create a new energy source based off of methane. All biogases (methane and related gasses) are derived from organic matter. When an animal or plant dies, the bacteria and fungi eat away at the dead organisms causing it to decompose. The process of decomposition causes these gasses to be released as well. The gas that is released is called either final, nappe, or syngas.

If an organism has just died and it's left outside in the open air, you will get mostly methane or other light glasses, which can be used for cooking or heating homes. If an animal or plant has died and decomposition started, you will get mainly methane. If a plant has just been chopped up and put into a composting bin, you will also get mostly methane. If it is in the soil near other plants or living organisms it may be converted to nitrous oxide (N2O), which is used by many plants as fertilizer.

Biogas can be used for cooking

When biogas is burned at temperatures of 650 °C, it becomes a fuel that can be used to heat homes. This process releases carbon dioxide (CO2) and nitrogen (N2) into the air as waste products. The CO2 is released in small amounts by the end-product of burning the H2S.
