Special topic of biogas purification - Air separation

Biogas purification process

The main components of biogas and natural gas are CH4. The product gas purified by CH4 is biological natural gas (BNG), and pressurized to 25MPa is compressed natural gas (CNG). The biogas extraction device designed and produced by DEAR air separation can effectively remove impurities in biogas, such as condensate water, hydrogen sulfide and carbon dioxide, and maintain a very high recovery rate of CH4.

Energy Saving

The patent technology of ultra-low pressure discharge and energy saving obtained by DEAR air separation can reduce the energy consumption of equipment operation by 5%-15%, and save the operation cost for customers.

Remote intelligent monitoring system

DEAR early remote monitoring system can realize remote monitoring and early warning of field equipment, and can save the cost of on-site remote monitoring and air separation.

The first intelligent workshop of air separation in China

DEAR air separation has invested 30 million yuan to build an intelligent production workshop to ensure that the product quality is close to zero defect, improve the precision of biogas purification equipment and shorten the scheduled period.

Cooperation cases

DEAR air separation not only has unique advantages in the production of oxygen, nitrogen and argon in air separation, but also has obtained achievements and technologies of different grades from 20000 to 100000 in biogas purification, carbon dioxide recovery and purification, coal bed methane liquefaction, coke oven gas purification and purge gas purification, etc., and has obtained a number of national practical technology invention patents Zhongyuan Oilfield Design Institute and some domestic well-known university research institutions have maintained good cooperation with DEAR air separation.

Case of DEAR and Power China

China Electric Power Construction Group signed a set of project with daily production capacity of 40000 cubic meters to purify natural gas with biogas in May 2018 through multiple comprehensive investigation and technical communication on DEAR air separation plant. This project is the first national pilot project of bio natural gas in Shaanxi Province.

Customer feedback

Since the project was put into use, the technology and after-sales service have been in place. Both the technical maturity, methane purity, methane yield, operation energy consumption and other indicators, as well as the equipment investment and system stability, safety, economy and practicability, have reached the domestic advanced level.
