Biogas produced by anaerobic process of digester is a kind of mixed gas, which is mainly composed of CH4, CO2 and water vapor. It is a very flammable gas, but it also pollutes the environment, and even has serious security risks. Therefore, it is necessary to pretreat biogas in order to make better use of it and avoid harm.
Biogas power generation is a widely used biogas application project. However, biogas contains impurities and its flow, pressure, temperature and concentration are very unstable. If biogas is directly used in gas-fired power generation, it will cause corrosion, wear and other problems of gas-fired generator equipment, and then seriously shorten the life of gas-fired generator. Therefore, biogas must be pretreated before application.
In order to meet the quality requirements of biogas generator for biogas, it is necessary to add biogas filtration pressure system to purify and pressurize biogas and send it to biogas generator for power generation. In order to obtain higher economic and environmental benefits, biogas pretreatment should be carried out more effectively to improve the quality of biogas, increase the utilization rate of biogas power generation, and reduce the damage to the generator.
