Our Company Successfully Commissions China's First Pilot Project for Helium Extraction from Coalbed Methane
Coalbed methane refers to unconventional natural gas primarily composed of methane enriched in coal seams, containing complex gas components such as carbon dioxide and nitrogen, serving as an important supplement to natural gas resources. Due to factors like geological conditions and burial depth, the helium content in coalbed methane exhibits significant fluctuations.
Helium is a scarce strategic resource widely used in fields such as leak detection, optical fibers, semiconductors, and scientific research. Currently, the primary source of helium production comes from the recovery of associated helium in natural gas. However, the helium content in China's natural gas is generally low, making helium resources relatively scarce. Therefore, the development of new and advanced natural gas helium extraction technologies and equipment is crucial to address China's helium shortage.current situationWith the rapid development of technologies such as membrane separation, pressure swing adsorption, and temperature swing adsorption, the extraction of helium from low-helium-content natural gas and coalbed methane has become feasible. In recent years, various research institutions, high-tech companies, and otherscientific and technologicalentities have been...BOGHelium extraction and high-helium-content pipeline gas helium extraction projects are highly sought after, withnovelhigh-efficiency, low-costhelium extraction technologies and equipmentresearch and developmentStill in the ascendant.
Our company has successfully delivered the first domestic pilot project for helium extraction from coalbed methane, which underwent three months of research, development, and assembly. After intensive on-site construction, installation, and commissioning, it has smoothly produced99.999%qualified helium gas, ***with purity meeting6Nthe requirements for electronic grade.

Diagram2The illustration shows the temperature swing adsorption technology powered by the high-low temperature integrated unit developed by *** for this project. This technology does not use liquid nitrogen but solely relies on electric power to drive the integrated unit, providing both low-temperature adsorption and high-temperature regeneration environments. Compared to the liquid nitrogen cryogenic purifiers produced by our company and peers, this technology and equipment are particularly suitable for scenarios without liquid nitrogen. They offer advantages such as ease of use, high integration, lower costs than liquid nitrogen purifiers, and broader applicability.
