SYSTEM AND METHOD OF COOLING WITH HYDROGEN CAPTURE Russian patent published in 2015 - IPC B01D53/14 

FIELD: oil and gas industry.

SUBSTANCE: cooling system includes hydrogen capture system, cooling system and control device. The hydrogen capture system is intended to remove carbonaceous gas from synthetic gas with obtainment of captured carbonaceous gas. The captured carbonaceous gas has purity of at least 80 vol % of carbon dioxide (CO₂). The cooling system includes gas expansion unit and cooling agent circuit. Gas expansion unit is intended for expansion of captured carbonaceous gas to reduce temperature of captured carbonaceous gas with production of carbonaceous gas of low temperature. Cooling agent circuit is intended for usage of carbonaceous gas of low temperature to cool at least one solvent for at least one gas purifier. Control device includes programs to regulate cooling system in order to regulate temperature related to cooling of at least one solvent for at least one gas purifier.

EFFECT: in comparison with standard cooling cycles the claimed system is relatively simple; it requires less space for layout and improves general efficiency by using the available carbonaceous gas.
