How does GSEs LIQUEX™ technology work for coal liquefaction?
Coal is ground into fine particles, for example, those ranging in size from 10 mesh (2 mm) to 60 mesh (0.25mm). The coal is then mixed with GSE’s proprietary reagent, GSX™, in a simple mixing vessel at ambient pressure and temperature to dissolve the organic matter in coal. The resultant mixture is conveyed to a filtering system to separate it into two products, a liquid stream and a particulate solid stream. The liquid phase generally consists of GSE’s proprietary reagent, most of the bituminous organic matter (liquid coal) and the pollutants (e.g., sulfur and nitrogen) in coal. The particulate solid stream mainly comprises inorganic mineral matter and carbon as well as some residual pollutants and moisture. Much of the reagent can be separated from the liquid stream via a simple distillation for recycling, and the pollutants remaining in either the liquid coal or reagent can be treated with relative ease.
