INSTALLATION FOR REFINING OF CRUDE OIL AND OIL PRODUCTS Russian patent published in 1995 - IPC

FIELD: fractionation of crude oil and oil products by instantaneous evaporation in hydrocyclones. SUBSTANCE: installation comprises a feedstock container communicating through a pipeline with a water-evaporating apparatus. Said pipeline passes through a system of heat exchangers serving as receivers of fractions condensed in cyclones. The lower part of the evaporating apparatus is connected by a pump with the heated furnace coil then with the mixer of the warmed up feedstock and heat carrier. The mixer is further connected by pipelines with a vacuum mixture evaporator provided with a metal screen with induced electric charge, and has a lower branch pipe in the form of a tubular hydraulic seal communicating with a condensed liquid receiver. Besides, the internal discharge pipe of the evaporator is connected to a vacuum pump via a bank of successive cyclones. The evaporator and each cyclone are interconnected by pipelines with built-in coolers for vapors escaping from the cyclones. Each cooler is also in communication with the corresponding receiver of condensate discharged from the cyclone. The discharge line of the vacuum pump is connected to a furnace for burning of waste vapors. EFFECT: improved design. 4 cl, 1 dwg
