FIELD: petroleum industry; devices for vacuum distillation of raw.
SUBSTANCE: device for vacuum distillation of raw, predominantly petroleum raw, consists of a vacuum rectifying column with main lines of raw input and diversion from it steam-gas medium, distillate and the distillation rest, the liquid-gas jet device, a separator, the pump, the complementary liquidgas jet device, a complementary separator, the complementary pump. The liquidgas jet device is connected by a gas input with a diversion mainline steam-gas medium, by a fluid input it is connected with a pump output, by a mixture output it is connected with a separator having an output of compressed gas and an output of a liquid phase, connected with the pump. The complementary liquidgas jet device is connected by a fluid input with an outlet of the complementary pump; by a mixture output is connected with the complementary separator having an output of gas medium and an output of liquid medium, connected with the complementary pump. Unit is supplied by an absorber having an input and an output of a liquid sorbent, an input of gas and an output of the purified gas, and by the vacuum degasser having an output of degassed fluid, an output of degassing gases, connected with a gas input in the complementary liquidgas jet device, and the input of a liquid phase connected with an output of a liquid phase from a separator. The gas input in an absorber is connected with an output of compressed gas from a separator and an output of gas medium from a complementary separator.
EFFECT: quality improvement of the distillation product which are getting out a separator in the form of excess of a liquid phase; reduction in environmental pollution.
