Coal Mine Gas

    The main component of coal mine gas is methane, which can be used as clean energy. The annual emission of CMM in China is as high as 20 billion cubic meters.

    For high-concentration coal mine gas with methane over 30%, Fairyland can provide pre-treatment system and flare system for engines; For the high-concentration coal mine gas to municipal pipeline transportation project with methane over 30%, the deep dehumidification system can be provided, which effectively solves the problem of freezing and water blocking problems of gas pipelines in winter and interruption of residential gas supplying;

    For low-concentration coal mine gas with below 30% methane, Fairyland can provide VPSA vacuum pressure swing adsorption purification technology, which can increase the methane concentration by about 10% to more than 30%.  This way is more helpful to the utilization of the gas utilization; Moreover, for low-concentration gas to power generation systems with methane concentrations below 30%, Fairyland can provide the absorption dehumidification technology, which effectively solves the problems of high pressure lost by gas piping, lower injection pressure before engines and high energy consumption caused by traditional electric-refrigeration process.
