Abstract:This paper discusses the improvement design for water washing system in Project HCFC-22 of
12000 tpa.In the design,height of water column is increased and steam-water separation process of diluted acid from the water washing system is improved,which brings into full play the extraction and separation abili-
ty of water washing column,meets the requirement of production and reduces the cost.In the meantime,environ-
