7×10~4t/a硫磺回收装置设计特点及问题探讨

DISCUSSION ON THE DESIGN FEATURES AND PROBLEMS OF 70KT/A SULFUR RECOVERY UNIT

镇海炼化公司 7× 10 4 t/a硫磺回收装置引进荷兰Comprimo公司SCOT硫回收技术 ,采用二级常规Claus制硫加SCOT尾气净化工艺 ,设计总硫转化率 99.8% ,尾气中SO2 排放量和排放速率均低于国家标准。装置于 1999年 6～ 7月期间开工投运 ,并通过了性能考核。本文介绍了 7× 10 4 t/a硫磺回收装置设计特点和装置开工、考核及运行情况 ,并结合开工及生产过程中出现的问题进行讨论。同时介绍了为保证装置平稳运行进行的整改情况。

During June and July 1999,the 70kt/a sulfur recovery unit has been commissioned and started up.The unit utilizes Claus and Scot technologies,and its basic engineering design was performed by SE&C.This paper presents the designing features of 70kt/a sulfur recovery unit as well as its erection,startup,check results and operation.The problems in operation and their solutions are discussed.The innovation of the unit is also introduced.
