The normal practice in the coal preparation plant is to remove the water from the fine coal slurry by vacuum filtration and drying. Conventional vacuum filtration typically produces filter cake moisture containing in the range of 25 to 30 weight percent from minus 28 mesh coal slurries. Although the desired product quality can be obtained by using thermal dryers, there are problems associated with these equipment such as high capital costs and the greatest potential source of air pollution in a coal cleaning plant. In the present research project, an alternative to thermal drying, hyperbaric filtration which has shown potential in lowering moisture content in fine coal to about 20 percent level, is being investigated in detail. This project will essentially focus on developing fundamental information on particle-liquid interaction during hyperbaric filtration and applying the knowledge in developing optimum conditions for the pilot plant testing of the hyperbaric filter system.
