METHOD AND DEVICE FOR SHORT-FLOW DESULFURIZING RECYLED HYDROGEN

摘要

A method for short-flow desulfurizing recycled hydrogen, involves the following steps: (a) subjecting recycled hydrogen mixed gas to remove hydrocarbon (10), in order to separate disperse phase heavy hydrocarbon liquid drops from continuous phase recycled hydrogen, and obtain heavy hydrocarbon phase and sulfur-containing mixed phase; (b) further separating the mixed phase to remove sulfide and obtaining sulfur-free recycled hydrogen; (c) further separating sulfur-free recycled hydrogen to remove amine liquid (9) and obtaining purified recycled hydrogen (6). A device for short-flow desulfurizing recycled hydrogen is also provided.
