INSTALLATION FOR PROCESSING LIQUID HYDROCARBONS Russian patent published in 2019 - IPC C10G7/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the field of oil refining industry, namely, equipment for the processing of liquid hydrocarbons, and can be used in refineries. Installation for processing liquid hydrocarbons, contains successively connected kiln, distillation column, first, second, third air coolers, evaporator and separator, at the same time, the distillation column in the upper part contains a line for discharging the light gasoline fraction, communicated with the first air-cooling unit and the processing tank for collecting the light gasoline fraction, in the side take-off, a line for withdrawing the diesel fraction and non-evaporated heavy gasoline fraction, communicated through the first level control with the first entrance to the stripping column, the upper output of which is connected to the entrance of the second air-cooling unit, the output of which is communicated through the first ejector with the technological tank for collecting the heavy gasoline fraction and the first circulation pump, the second outlet of the stripping column located in its lower part is connected through the second regulator to the evaporator inlet, the first outlet of which is connected to the second inlet of the stripping column located in its lateral selection, and the second outlet of the evaporator is connected to the inlet of the third air-cooling apparatus, the outlet of which is connected to the process tank for collecting the light diesel fraction, in the lower part of the distillation column, there is a line for withdrawal of the fuel oil fraction and the non-evaporated part of the heavy diesel fraction, communicated through the third level control with the first input of the bottom tank, the first output of the bottom tank is connected to the input of the separator, the first outlet of which, located in the upper part, is connected to the inlet of the fourth air-cooling apparatus, communicated through the second ejector with the technological tank for collecting the heavy diesel fraction and the second circulation pump, and the second outlet of the separator, located in its lower part, communicates with the second inlet of the bottom tank, the second output of the bottom of the tank through the process pump communicates with the fifth air-cooling unit, the output of which is connected to the technological tank for collecting fuel oil through the fuel oil drain line, which passes through the inner tube space of the evaporator.

EFFECT: reducing the degree of watering and the content of residual fractions in the target products, as well as ensuring a minimum level of emissions of pollutants.
