For the replacement of hydrogen sulfide in biogas, the desulfurization efficiency can reach 99%, which can optimize the purification of biological gas and improve the thermal efficiency during the production of biological gas. If the gas purity requirement is higher, double towers can be used. Steel or glass.
Biogas desulfurization is based on the impact of hydrogen sulfide in biogas on the environment, equipment, pipelines, instruments, etc., resulting in pollution and corrosion. Therefore, whether directly used for combustion or biogas power generation, biogas must be treated with necessary desulfurization, decarburization, dehydration, dust removal, etc.
According to the composition of the feed, the H2S content in the biogas produced is slightly different, and the general concentration is 1~12g/m3. For raw materials with high protein or sulfur salt content, the H2S content in the biogas will be higher when it is delivered locally. According to the urban gas standard, the H2S content in LPG shall not exceed 20mg/m3.
The direct desulfurization method is generally adopted for the desulfurization of biogas produced by anaerobic digestion, which can be divided into dry method, wet method and biological desulfurization according to the principle. Biological desulfurization is a new type of desulfurization method that has emerged in recent years to replace chemical desulfurization, and it can overcome the shortcomings of chemical desulfurization in many aspects.
