HYDROGEN-BEARING GAS SEPARATION SYSTEM (VERSIONS) Russian patent published in 2024 - IPC B01D3/14 C07C7/11 F25B15/02 C01B3/02 

FIELD: various technological processes.

SUBSTANCE: invention relates to equipment for hydrotreating middle distillate fractions and can be used in oil refining industry. Invention relates to a hydrogen-containing gas separation system, comprising a hot separator with lines of a heavy fraction and light fraction vapours, on which there is a heat exchanger for production of water vapor, air and water coolers and a cold separator with lines of circulating hydrogen-bearing gas and light fraction. Instead of a heat exchanger for producing water vapor, an absorption refrigerating machine heater is installed, instead of a water cooler, an absorption refrigerating machine cooler is installed, wherein absorption refrigerating machine heater and absorption refrigerating machine cooler are connected to absorption refrigerating machine by heat carrier and coolant input/output lines, respectively. Invention also relates to a version of the hydrogen-bearing gas separation system.

EFFECT: increasing hydrogen concentration in circulating hydrogen-bearing gas.
