Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates.
FGX technology is an innovative, efficient, coal preparation process using air. Typically coal processing is completed with water, which is a very costly and scarce resource requiring stricter permits to operate. The FGX dry coal washing process is proven successful, cost effective, environmentally friendly, and requires only an air quality permit.
