METHOD OF IN-LINE DISTILLATION OF MAZOUT AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2000 - IPC

FIELD: distillation of mazout in petroleum refining. SUBSTANCE: stepped fractionation of mazout in the course of its evaporation is effected through separation of vapors followed by their condensation. Separation of vapors includes their washing. Recuperative heater system includes condensers and final coolers. Provision is made for furnace for stepped heating and evaporation of mazout; each stage is made form of evaporator with steam separator. Each stage of fractionating device consists of steam separator and condenser connected with it. All condensers are connected with vacuum forming system by means of lines. Recuperative heater system includes at least one stage of fractionating device. Steam separators includes steam scrubbers. EFFECT: reduced power requirements; reduction of toxic emissions. 5 cl, 1 dwg
