    The future development of a non-evaporative brown coal dewatering technique called Mechanical Thermal Expression (MTE) will produce large volumes of acidic, salty and organic rich product water. The overall viability of the MTE process will, in turn rely on the availability of a simple and energy-efficient water remediation strategy.Compared to nitrogen drying process, the mechanical thermal expression (MTE) drying process, a typical non-evaporation drying process with great potential in large-scale application, results in significantly different changes in characteristics of lignite such as pore structures, mineral matters contents and particle size.Effects of the evolutions of coal properties during ...Mechanical thermal expression (MTE) ..... 36 RD needs for coal drying ............................................................................................... 37 Power Generation from Coal Power Generation from Coal FINAL - OECD iLibrary
