240 kt/a硫磺回收装置运行探讨

介绍中海油惠州石化有限公司240 kt/a硫磺回收装置工艺流程、开工及标定情况,对其运行过程中存在的问题进行了分析并提出了解决方案。通过优化胺液吸收再生操作、采用液硫密闭收集、将S Zorb再生烟气引入一系列硫磺回收装置尾气加氢反应器等措施后,240 kt/a硫磺回收装置总硫转化率大于97.8%,排放气体ρ(SO₂)小于100 mg/m³。

Discussion of 240 kt/a sulphur recovery unit operation

Process flow,start-up and calibration of 240 kt/a sulphur recovery unit in CNOOC Huizhou Petrochemical Co.,Ltd.is introduced.Existing problems in operation was analyzed and propose solutions were proposed.After transformation of optimizing amine liquid absorption and regeneration,adopting liquid sulphur closed collection,introducing S Zorb regeneration flue gas into a series of sulphur recovery unit tail gas hydrogenation reactor,total sulphur conversion in 240 kt/a sulphur recovery unit was above 97.8%,andρ(SO2)in exhaust gas was less than 100 mg/m^3.
