- 摘要:
- 高含硫气田通常采用常规克劳斯工艺+SCOT尾气处理装置进行酸气处理。结合川东北高含硫气田工程实际情况，研究了在设置有SCOT尾气处理装置的高含硫气田工程中的硫磺回收装置的工艺选择，主要对二级常规克劳斯工艺和三级克劳斯工艺进行比选。通过对两种不同硫磺回收工艺情况下硫磺回收装置和尾气处理装置的一次投资（主要包括设备费用、材料费用、土建费用、结构费用和施工费用）和20年操作费用（主要包括催化剂消耗和蒸汽消耗）综合进行量化比较，发现在设置有SCOT尾气处理装置的高含硫气田工程采用三级常规克劳斯硫磺回收工艺更为经济合理。
In high sour gas field development， conventional Claus process and SCOT tail gas treatment process are usually adopted to treat acid gas. In combination with practical situations in CDB High Sour Gas Field development， described is process selection for sulfur recovery unit in SCOT tail gas treatment， mainly including comparison and selection of conventional 2-stage Claus process or conventional 3-stage Claus process. Through quantitative comparison on primary investment costs（mainly including equipment costs， material costs， civil engineering costs， structure costs and installation costs） and operation costs in 20 years （mainly including catalyst and steam consumption costs） of two different sulfur recovery processes， it is considered that conventional 3-stage Claus sulfur recovery process in SCOT tail gas treatment is more economic and reasonable. Accordingly， this sulfur recovery process may be recommended in future similar projects.
