Abstract

PURPOSE: To dehydrate moisture-contg. coal at a high dehydration efficiency, by heating the moisture-contg. coal together with a solvent and a dehydrated slurry obtd. from the present process, separating the resulting mixture into a vapor phase contg. steam and a slurry by means of gas-liquid separation and recycling part of the dehydrated slurry for reuse.
CONSTITUTION: A moisture-contg. coal such as caking coal or brown coal contg. about 10wt% or more moisture and a solvent are mixed in a coal to solvent wt. ratio of 1/0.7W1/10, and crushed by crusher 1, to form a slurry. In slurry tank 2, one part of the slurry is mixed with about 0.2W10pts. of a dehydrated slurry obtd. from the present process, and the resulting slurry mixture is heated to 100W350°C in furnace 3, and separated into a gas phase contg. steam and the purpose dehydrated slurry. The gas phase is led to still 5, where a heavy oil is recovered. The solvent is recovered in water separator 6, and part of the dehydrated slurry is returned to the slurry tank 2 and recycled to be reused.
