What is Meant by Amine Gas Treating for Methane Gas/Biogas?
The biogas from AD processes needs further refining before it can be used for normal purposes in standard retail equipment. A common way to achieve this is by Amine Gas Treating.
Amine Gas Treating refers to a group of processes that use aqueous solutions of various amines to remove hydrogen sulphide (H2S) and carbon dioxide (CO2) from gases.
Amine gas treating, an industrial scale process which removes acidic gaseous components, is often used to remove hydrogen sulphide from natural gas.
A typical amine gas treating process includes an absorber unit and a regenerator unit as well as ancillary equipment.
If the levels of hydrogen sulphide in the gas are high, gas scrubbing and cleaning equipment (such as amine gas treating) will be needed to process the biogas to within regionally accepted levels.
Before a raw natural gas containing hydrogen sulphide and/or carbon dioxide can be used, the raw gas must be treated to remove those impurities to acceptable levels and that is commonly done by using an amine gas treating process.
