METHOD AND APPARATUS FOR COMBINED PRODUCTION OF A MIXTURE OF HYDROGEN AND NITROGEN, AS WELL AS CARBON MONOXIDE USING CRYOGENIC DISTILLATION AND CRYOGENIC WASHING

摘要

FIELD: chemical or physical processes.;SUBSTANCE: method for combined production of a mixture of hydrogen and nitrogen, as well as carbon monoxide using cryogenic distillation and cryogenic washing, in which liquid enriched with methane (45) is fed to first intermediate level of scrubber column (15) as first washing liquid, and at least one nitrogen-enriched liquid (73) is introduced to a level above the first level of the scrubber column as a second washing liquid, and mixture of hydrogen and nitrogen is removed in form of upper gas (27) from a scrubber column.;EFFECT: invention discloses a method and an apparatus for combined production of a mixture of hydrogen and nitrogen, as well as carbon monoxide using cryogenic distillation and cryogenic washing.;10 cl, 3 dwg
