Methane released by coal mining operations, known as coal mine methane (CMM), is a potent greenhouse gas (GHG). Currently a fraction of CMM emissions is recovered for safety purposes and sometimes used as an energy source. Meanwhile, more than 50% of all CMM originates from mine ventilation systems and remains virtually unexploited.
Shengdong is a leader in the development, building and operation of projects which capture and destroy methane emitted by underground coal mines.
Shengdong VAM converts methane into carbon dioxide and water vapor using the proven principle of regenerative thermal oxidation (RTO). RTO is based on the cyclic reversal of the airflow through multiple vessels filled with heat absorbing ceramic media that act as a heat exchanger. Thus, the Shengdong VAM system destroys VAM in a self-sustained manner even at extremely low methane levels.
