生物燃气净化处理技术研究

Research on Biogas Purification Technology

对生物燃气实施净化处理涉及脱除硫化氢、水、卤化烃、硅氧烷、氧、氮、固体颗粒物等多道工序,尽管成熟技术很多,但由于生物燃气气源组成、杂质含量等指标有差异,且下游利用环节对气质要求各不相同,因此,没有对每个项目都能适用的成套净化处理工艺。需要因地制宜,结合具体工程项目的造价、运行成本、场地条件、操作强度等因素,对各类工艺技术集成优化并进行技术经济分析,以期达到经济效益最优化目标。介绍了生物燃气脱除硫化氢、水、硅氧烷、氧、氮等净化处理技术。

The biogas puritication involves the removal of hydrogen sulfide, water, halogenated hydro- carbons, silicones, oxygen, nitrogen and solid particles and other procedures. Although there are many mature technologies, but because the components, impurities and other indexes of biogas the gas quality requirements resources are different, and in the downstream use sectors vary, there is no one set of purification processes that can be applied to each project. According to local conditions, combined with the investment, operating costs, site conditions, operating strength and other factors of a specific project, various types of technologies should be integrated, optimized and analyzed technically and economically in order to achieve economic optimization objectives. The removal of hydrogen sulfide, water, silicone, nitrogen, oxygen and other purification techniques are described.
