This project was formally put into operation in May 2015.The project enables 8.9 million Nm3 methane/y to be used for power generation, reduces greenhouse gas emissions by 1.4 Mt/y of CO2e 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 CO2Up 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.Dürr Systems, CTS has also engineered, built, installed and commissioned the first full-scale VAM oxidation system in the USA, which has been successfully operating since 2013. Furthermore, the company has begun the engineering phase of several new VAM/CMM oxidation and utilisation projects throughout China.
