五种克劳斯延伸硫磺回收装置运行情况的对比分析

Comparative analysis of operation situation on the five extended Claus sulfur recovery units

对中国石油西南油气田公司所属的CBA、MCRC、SuperClaus、Clinsulf-SDP、CPS 5种克劳斯延伸硫磺回收装置应用情况进行了详细分析,就工艺、能耗、投运后出现的问题、装置操作难易程度及适应性等方面进行了综合对比。结果表明,这5种装置各有特点,其运行均是成功的,可达到设计的硫收率。CPS工艺兼备了CBA及MCRC工艺的优点,且在节能降耗上充分利用其烟气余热。SuperClaus作为一个稳态运行的工艺,不仅硫收率稳定且关键设备毋须进口,投运后问题较少。Clinsulf-SDP工艺因系等温反应,可使克劳斯反应进行得更为彻底,但对设备性能要求高,催化剂不便更换。

Five extended Claus sulfur recovery processes including CBA,MCRC,SuperClaus,Clinsulf-SDP and CPS applied in sulfur recovery units of PetroChina Southwest Oil & Gasfield Company are minutely analyzed.Based on the comprehensive comparison of the process,energy consumption,problems after commissioning,difficulty level and adaptability of the operation,the results showed that each of them has its own specialty,and can reach the design value of sulfur yield as well as successful operation.CPS has the advantages of CBA and MCRC,and can make the best use of flue gas waste heat for lowering energy consumption.SuperClaus is a stable process which has stable sulfur yield and does not request imported key equipments,it also has the advantage of less problems after putting into operation.As the Clinsulf-SDP is a kind of isothermal reaction,the Claus reaction could be more completely.However,it also has the disadvantages of high requirements for the equipment performance and inconvenience of replacing the catalyst.
