  • Integration of pressure swing adsorption with hydrocracking for improved hydrogen and liquids recovery
    Patent number: 11091704
    Abstract: The invention provides a process for producing hydrogen for a hydrogen consuming process comprising obtaining a net gas stream containing hydrogen, compressing the gas stream to a pressure of 20.7 to 68.9 bar (300 to 1000 psig) to produce a compressed gas stream; sending the compressed gas stream to a pressure swing adsorption unit to be separated into a hydrogen stream and a fuel gas stream; purging the pressure swing adsorption unit with an external purge gas stream from a hydroprocessing unit off gas; treating the off gas with a thermal swing adsorption unit to remove water and other impurities prior to purging the pressure swing adsorption unit, and using a protective adsorbent layer in the pressure swing adsorption unit to adsorb impurities from the external purge gas.
