HYDROCRACKING SYSTEM, PRESSURE REDUCTION METHOD AND PRESSURE REDUCTION UNIT Russian patent published in 2024 - IPC C10G47/00 F16K1/34 F16K25/04 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to a crude oil hydrocracking system comprising: a liquid-phase hydrocracking (LPH) section including at least one LPH reactor; section of gas-phase hydrocracking (GPH), including at least one GPH reactor; a separation section between the LPH section and the GPH section, including at least one high-pressure separator and at least one low-pressure separator, as well as at least one flow supply line from the high-pressure separator to the low-pressure separator, wherein said at least one flow supply line comprises a reducing valve and a throttling cartridge located in the supply line downstream of the reducing valve; heat carrier supply line to flow supply line and reducing valve. Invention also relates to a method of reducing pressure in the separation section of a hydrocracking system of oil stock and a unit for reducing pressure in the separation section of a combined hydrocracking system.

EFFECT: use of the proposed invention allows to increase the reliability of the system due to the reduced risk of erosion wear and destruction of the system components in the separation section.
