垃圾填埋气净化利用集成系统工艺研究

摘要

Purification and utilization of Landfill gas (LFG) was economically feasible and environment friendly.In this paper,the separation of hydrogen sulfide,carbon dioxide and oxygen from landfill gas and liquefaction for purified landfill gas were introduced.Moreover,the purified landfill gas was designed to be used as an alternative fuels for vehicles,which could realize the maximum value for landfill gas utilization%垃圾填埋气的净化利用是一项经济可行且对环境有益的技术.文章对城市生活垃圾填埋气中甲烷、硫化氢、二氧化碳、氧气的分离和液化提纯技术进行了详细介绍,重点设计了一种将填埋气提纯液化为车用燃气的工艺,最大程度实现垃圾填埋气资源的利用价值,为我国发展循环经济道路提供实践参考.
