By optimizing the drying process, the efficiency of brown coal power plants could be increased by 46% [19]. At present, burning brown coals produces more carbon dioxide (about onethird more), than burning black coals [18]. When the moisture of the coal is reduced from 60 to 40%, the relative reduction of CO 2 /MWh can reach 30% [20]. Thus ...

With the rising cost of energy and fuel oils, clean coal technologies will continue to play an important role during the transition to a clean energy future. Victorian brown coals have high oxygen and moisture contents and hence low calorific value. This paper presents an alternative non evaporative drying technology for high moisture brown coals based on osmotic dewatering.
