METHOD OF CONDENSATE STABILISATION WITH PRODUCTION OF SOLVENT AND KEROSENE-GAS OIL FRACTION, AND SYSTEM FOR IMPLEMENTATION OF THE METHOD

摘要

FIELD: chemistry, organic.;SUBSTANCE: invention is related to a method for condensate stabilisation with production of solvent and kerosene-gas oil fraction comprising fractionating of raw stock and characterised in that the raw stock is fed to a heat exchanger wherefrom it is fed to a heater having live steam as a heat carrier, and then the raw stock heated to 140°C, at a pressure of 4 atm., is delivered to a hydraulic cyclone where the hydraulic cycloning process is carried out comprising creation of vacuum at the flow rotation centre, which results in a process of separation of light hydrocarbons that constitute the base of the solvent in the form of a vapour-gas mixture, the mixture being cooled in a condenser-cooler by water not higher than 15°C and collected in another tank in the form of solvent, dry gas from the mixture being supplied to a furnace while heavier hydrocarbons that are the base of the kerosene-gas oil fraction, in the form of separated liquid, are accumulated in a tank and fed to the heat exchanger at a temperature of 120°C, the heat exchanger performing heat transfer from hotter heavy hydrocarbons (the kerosene-gas oil fraction) to cold raw stock. A plant for realisation of the described method is also proposed. The method makes it possible to produce solvent and kerosene-gas-oil fraction in a single process and to simplify the design of the plant.;EFFECT: production of a solvent and a kerosene-gas oil fraction in a single process.;1 dwg
