  • Production Of Liquid Hydrocarbon Mixture For Refining Petroleum (AREA)

Abstract

PURPOSE: After preheating, a slurry mixture of undried brown coal and a solvent is heated to separate vapor from liquid where the generated vapor is utilized as the heat source for preheating and the slurry is reheated under pressure to prepare a slurry suitable for liquefaction thereby the heat consumption is reduced.
