ABSTRACT:
Bitumen-containing material is processed by distillation with a solid heat-carrier with subsequent gasification of the distillation residue and combustion of the gasification residue in an aerofountain furnace. During gasification, the formed flue gas and ash are heated and part of ash is used as the heat-carrier. The flue gas and ash are withdrawn from the process simultaneously in the form of their suspension in air, from which the heat-carrier is isolated for the distillation process, the consumption of the heat-carrier being controlled by withdrawing part of the suspension containing fine fraction of ash before the heat-carrier is isolated.
The device for realization of the proposed method comprises an aerofountain furnace and is provided with a means for delivering the heat-carrier into the reactor, which is actually a separator with leading-in and leading-out gas ducts and a by-pass gas-duct provided with a controlled valve intended to control the delivery of the aerosuspension through the bypass gas-duct.
