Coalbed & Industrial Gas Recovery

Coalbed methane (CBM) is widely present in both unmined and active coal seams, often existing in the form of gas with characteristics such as low pressure, high methane concentration, and significant production fluctuations. Due to dispersed well layouts, high water content, and complex impurity compositions, CBM and mine gas are frequently vented or flared during extraction, leading to resource wastage and emission pressures, severely impacting mine safety and environmental compliance.

With increasingly stringent requirements for mine safety, clean energy development, and emission reduction, efficient recovery of CBM and mine gas has become a critical focus in unconventional gas management, necessitating modular, standardized, and engineered solutions tailored to on-site conditions.

Solution Approach

KAITIANGAS addresses the high water content, high corrosiveness, and significant volatility characteristics of CBM and mine gas by developing skid-mounted, highly integrated, and intelligent recovery systems tailored to the actual deployment needs of coal mine stations. We offer comprehensive professional services encompassing project consulting, engineering design, equipment manufacturing, EPC execution, and system commissioning, supporting the safe and efficient recovery and centralized processing of multi-well gas sources in mining areas.
