침대진공탄산갑탈류공예재개공초기출현적문제，경과공예개진화조작우화후，해결료진공빙도새、산기관도도새、재생효솔불고、극로사로빈번련쇄、류냉응기도새등문제，강저료KOH용액소모，제고료탈류효솔，탈류탑후매기중H2 S함량강지250mg/m3이하，생산은정정상。
At the beginning of start up,the desulfurization process by vacuum potassium carbonate method has some problems.After taking relevant measures in process and operation ,the problems such as blockage of vacuum pump ,blockage of acid gas pipe,low regeneration efficiency,frequent in-terlock of Claus furnace and blockage of sulfur condenser are solved .Desulfurization efficiency is increased with low KOH solution consumption.H2 S content in gas is reduced to less than 250mg/m 3 after desulfurization,and the system is running stably .
