INSTALLATION FOR PROCESSING OF CRUDE HYDROCARBON Russian patent published in 2021 - IPC C10G7/00 

FIELD: petrochemical industry.

SUBSTANCE: invention relates to an installation for the processing of hydrocarbon raw materials containing a block of topping and dewatering, an intermediate tank, an oven, the first and second distillation columns connected by means of a pipeline system with sequentially connected first, second, third and fourth heat exchangers, with the first, second, third, fourth and fifth air cooling apparatus, with an evaporator, with the first, second, third and fourth tanks for collecting liquid hydrocarbon fractions, moreover, the inlet of the inter-tube space of the first heat exchanger is connected to the outlet of the intermediate raw material tank, and the outlet of the tube space of the fourth heat exchanger is connected to the inlet of the furnace, the outlet of which is connected to the inlet of the first distillation column, in the lower part of which there is a fuel oil discharge line connected to the evaporator tube space, which is connected to the inter-tube space of the third heat exchanger, the outlet of which is connected in series with the fourth and fifth air cooling devices and further with the fourth fuel oil collection tank, and the top of the first distillation column is connected through the inter-tube space of the fourth heat exchanger with the lower part of the second distillation column, the top of which is connected through the tube space of the first heat exchanger and the first air cooling unit with the first tank for collecting gasoline fraction, and the middle part of the second column is connected through the second air cooling unit with the second tank for collecting kerosene fraction, and the bottom of the second distillation column has a diesel fraction discharge line, communicated through the inter-tube space of the evaporator with the inter-tube space of the second heat exchanger, which is connected through the third air cooling unit to the third tank for collecting diesel fraction.

EFFECT: increase in the efficiency of production, the quality of the products obtained.
