At present, there are still many processes used for biogas purification, separation and purification on the market, such as absorption method, pressure swing adsorption method, low-temperature condensation method, membrane separation method, etc. different process requirements, standards, investment and operation and maintenance costs are different... Therefore, when selecting biogas purification and purification, we should clarify our own purpose before selecting appropriate process technology and product services.
Clarifying their own needs is the basis for correct selection of biogas engineering process, equipment and services. GESHANG provides different service modes and personalized non-standard customized services to meet different needs of customers.

3. Process considerations
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.
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.
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.
