Biogas is a renewable energy source that is produced through the anaerobic digestion of organic matter, such as food waste, agricultural waste and other organic waste. However, biogas often contains sulphur compounds such as hydrogen sulphide, that can be harmful to the environment and equipment when it is burned for energy. Biogas desulfurization is the process of removing these sulphur compounds from the biogas to make it suitable for use as a clean energy source. Biogas desulphurization also called Biogas sweetening, as hydrogen sulphide considered as a sour gas, thus removal this sour gas termed as Biogas sweetening.
The removal of sulphur compounds from biogas is important because hydrogen sulphide is a corrosive and toxic gas that has the potential to damage equipment, pipes, and engines. Hydrogen sulphide from biogas can cause environmental problems like severe odour and might result in acid rain. Biogas desulphurization is necessary to ensure the quality of the biogas and to protect the environment, protect equipment and human health.
There are many methods for biogas desulphurization, including biological, chemical scrubbing, membrane filtration and activated carbon adsorption methods. Biological methods use microorganisms to convert H2S into elemental sulphur, while chemical methods use various oxidizing & neutralizing to reduce hydrogen sulphide concentration and membrane uses molecular filtration of selective gases. AQOZA has invented DesulphurPlus, a high-quality biogas desulphurization unit, where we offer advanced adsorption media for desulphurization.
