沼气发酵工艺技术经过多年的发展，已经相当成熟，能根据不同的原料、不同的处理标准要求，匹配各种不同的工艺，对应的沼气利用，净化提纯技术也得到了很好的发展，下面就目前市面上的工艺进行系统的介绍，以帮助客户在工艺选择时进行参考。
After years of development, biogas fermentation technology has been quite mature. It can match different processes according to different raw materials and different treatment standards. The corresponding biogas utilization and purification technology have also been well developed. The following is a systematic introduction to the processes on the market to help customers make reference in process selection.

系统工艺
System process
沼气提纯是一个系统工程，有一整套的系统工艺，就目前市面上工艺情况，主要有吸收法、变压吸附法、低温冷凝法、膜分离法等，不同工艺要求及标准也有差异，其中膜分离技术是目前世界上效率和效果TOP1好的沼气提纯技术，净化提纯后的气体能达到并网天然气标准，国内大部分采用的是脱硫、脱水等净化工艺，不是真正意义上的提纯，没有提高甲烷的浓度，并且经过研究发现未经提纯使用的沼气，是存在非常大的潜在风险。
Biogas purification is a systematic project with a complete set of systematic processes. According to the current process situation on the market, it mainly includes absorption method, pressure swing adsorption method, low-temperature condensation method, membrane separation method, etc. different process requirements and standards are also different. Among them, membrane separation technology is the highest biogas purification technology with high efficiency and effect in the world, The purified gas can meet the grid connected natural gas standard. Most of the purification processes used in China are desulfurization, dehydration and other purification processes, which are not purification in the real sense, and the concentration of methane has not been improved. After research, it is found that there is a very large potential risk for the unprocessed biogas.
膜分离沼气提纯技术是目前可靠、经济的沼气提纯工艺之一，我我们采用日本UBE公司的高性能气体分离膜通过此工艺技术甲烷的纯度可达到95%～97%，二氧化碳纯度及回收率可达85%～99.9%，另外还可分离回收单质硫，是未来沼气提纯深度利用的主流工艺。膜法气体分离工艺分为一级和二级膜处理工艺，能满足目前沼气提纯国家及国际净化提纯的标准要求，诸如天然气标准、车用天然气标准等。
Membrane separation biogas purification technology is one of the reliable and economical biogas purification processes at present. We adopt the high-performance gas separation membrane of UBE company in Japan. Through this process, the purity of methane can reach 95% ~ 97%, and the purity and recovery of carbon dioxide can reach 85% ~ 99.9%. In addition, it can separate and recover elemental sulfur, which is the mainstream process for deep utilization of biogas purification in the future. Membrane gas separation process is divided into primary and secondary membrane treatment processes, which can meet the current national and international standards for biogas purification, such as natural gas standards, vehicle natural gas standards, etc.
