The project enables 100 million Nm3 methane/yr to be utilized for power generation, reduces greenhouse gas emissions by 1.4 million tCO2e/yr, and significantly reduces the amount of coal dust particulates, a major source of air pollution. Methane’s global warming potential is 25 times more than that of CO2.
Up to 1,020,000 Nm3/h of ventilation air methane and 60,000 Nm3/h of coal mine methane are thermally oxidized in the project using Durr’s Regenerative Thermal Oxidizer (RTO) technology.
Up to 300,000 Nm3/h of hot exhaust gas is delivered to a boiler to generate water steam which is used for the generation of up to 30 MW of electricity by a turbine generator.
Mine and working safety is of key importance for the project. Part of the applied multi-level safety system is a rigorous hazardous operation and safety analysis in the pre-project phase.
Dürr Systems, Inc. CTS has also engineered, built, installed and commissioned the first full-scale VAM oxidation system in the United States, which has been successfully operating since 2013. Furthermore, Dürr Systems, Inc. has begun the engineering phase of several new VAM/CMM oxidation and utilization projects throughout China.
Regenerative Thermal Oxidizers included:
System square footage:
250,000 ft2 (23,200 m2)
1,020,000 Nm3/h of VAM and 60,000 Nm3/h of CMM
Available generated electricity:
Up to 30 MW
