Sector
Biogas Treatment & Cogeneration
The Biological Biogas Treatment for Energy Recovery project is an environmental gas-treatment installation in Taiwan, associated with biogas cogeneration.
Biogas utilisation requires consideration of gas quality, particularly the presence of hydrogen sulphide and other impurities that can affect downstream energy-generation equipment.
The project incorporates a biological desulphurisation process designed to remove hydrogen sulphide from the biogas stream.
Biological treatment uses sulphur-oxidising microorganisms to transform hydrogen sulphide into other sulphur compounds under controlled process conditions.
Within cogeneration infrastructure, gas conditioning plays an important role in protecting equipment and supporting the use of biogas for combined electricity and heat production.
