Ventilation Air Methane Abatement in Shanxi, China

Anguil Environmental Systems engineers have successfully designed, installed, and are now operating methane extraction, destruction, and energy recovery systems at six sites in Shangxi province in China. With Anguil's Regenerative Thermal Oxidizers (RTO) design, no auxiliary energy is required for combustion if adequate incoming methane concentrations are maintained. Anguil recommended the use of RTO technology, equipped with hot gas bypass, to destroy the ventilation air methane emissions and some low concentration of Coal Mine Methane from the drainage pipes at the coal mining facility.

Near-Zero Methane Emission Demonstration Area for Natural Gas Exploitation

The Southwest Oil & Gas Field has adopted a series of mitigation measures on fugitive emissions, venting methane emissions, and flaring. The project captured and reused a total of 490 million cubic meters of scattered gas and vented gas, 24 flaring torches were extinguished, and a total of 7,000 tons of methane emissions were reduced. Additionally, the project deployed methane leakage laser head monitoring equipment, gas cloud imaging equipment, pipeline infrasonic leakage monitoring systems, and inspection robots. These deployments led to a decrease in the methane leakage rate from 0.35% to less than 0.02%.

Weibei Pipeline Project for Associated Gas Recovery and Use

The Weibei Pipeline project effectively connects the associated gas resources of the Weizhou Southwest oilfield cluster with the natural gas market in Guangxi Province. The project promotes the recovery and utilization of methane from oil and gas extraction, significantly reducing methane emissions during offshore oilfield production. Additionally, it promotes the low-carbon and efficient utilization of energy, recovers 70.9 million cubic meters of associated gas, and provides the Guang Xi Region a continuous supply of energy for economic development.
