沼气净化技术及储存方式优化分析——以沼气工程为例

Optimization Analysis of Biogas Purification and Storage Technology

为优化沼气的净化技术和储存方式,文章对3座有代表性的畜禽养殖场沼气工程的沼气净化技术及储存方式进行了实证研究。通过对比分析得出:采用生物—化学联合工艺处理高H2S浓度的沼气是一种行之有效的沼气净化技术;北方地区宜采用干式储气柜;远距离输气适宜采用高压干式储气系统;沼气发电的工程采用干式双膜贮气罐更适合。

In order to optimize the technology of biogas purification and storage style, three typical biogas projects in the northern region of China were studied in this article. The following conclusions were drawn： the bio-ehemical combined method is an effective method for purification of high H2 S biogas ; the dry type biogas storage cabinet should be adopted in northern region; long-distance transmission of biogas should utilize the high pressure dry type biogas storage system; dry and double membrane biogas storage device was suitable for biogas power generation project. These were proved in the three biogas projects.
