In view of the global fossil fuel depletion crisis, the development and application of biomass fuel has become the focus of attention of all countries. Among them, biogas and biogas, as renewable power, have the characteristics of low cost and no pollution to the environment. They are high-quality environmental protection fuels to replace conventional fossil power. With the rapid development of large-scale biogas and bio natural gas projects, the demand for biogas biological desulfurization and purification to high value-added biogas is increasingly urgent. Biogas purification and purification skills have been applied and carried out in different degrees.
By removing the impurities in biogas to purify and purify the biogas, the purified methane gas concentration and incineration calorific value can replace natural gas as urban pipeline gas or vehicle gas, which can save and replace a lot of fossil power, reduce pollutants and greenhouse gas emissions, and greatly improve the economic benefits of biogas project and the deep application of biogas.
Biogas biological desulfurization
In China, the production and processing skills and commercial operation system of biogas have gradually matured. Through independent innovation, introduction and digestion of foreign mature and advanced anaerobic digestion technology of high solid content organic waste, large-scale biogas projects with grain straw, livestock manure and urban organic waste as treatment objects have also made breakthrough development The technology of biogas purification and purification has also been carried out, forming a series of relatively sophisticated skills.
Biological desulfurization process is a new desulfurization process, which is more and more welcomed by enterprises. The basic principle of biological desulfurization is to synthesize hydrogen sulfide and oxygen into sulfate by using the metabolic effect of Thiobacillus and Thiobacillus, and then remove the sulfur and hydrogen in biogas and desulfurize the product sulfate.
Although biogas biological desulfurization is relatively fast and has low operation cost, due to the introduction of impurity gas in the desulfurization process, it can not be removed in the follow-up process, and the process is not mature enough. Most of them use imported skills and equipment, so the investment cost is relatively high, which is about 3-5 times of that of conventional dry desulfurization.
The above is about the development trend of biological desulfurization, we should all understand, if you want to know more, please click http://www.hneee.net Official website.
