DRY GAS PURIFICATION FACILITY AND COAL GASIFICATION-COMBINED POWER GENERATION FACILITY

摘要

PROBLEM TO BE SOLVED: To purify a coal-gasified gas efficiently without increasing cost in a dry system, taking consideration of influence on succeeding apparatuses.;SOLUTION: A halide absorbent powder that absorbs most of a halide by blowing the halide absorbent powder to the coal-gasified gas g generated in a coal gasifying furnace 2 with a blowing means 22 is collected by a bag filter 21, mercury is removed in a state that a mercury absorbent in a mercury-removing reactor 23 is sulfurized by the coal-gasified gas g, and further the halide is precisely removed by a halide-removing reactor 24 having a small amount of halide absorbent.;COPYRIGHT: (C)2013,JPO&INPIT
