长庆气田Clinsulf Do硫磺回收装置应用效果

长庆气田第一净化厂从德国Linde公司引进了一套采用Clinsulf-Do工艺的硫磺回收装置，用于处理MDEA溶液脱硫装置产生的酸气。该装置于2004年5月初投产，生产运行情况良好，实际硫回收率在90%以上，装置排放尾气也达到国家相关环保排放标准。为此，介绍了该Clinsulf-Do硫磺回收装置的概况、装置主要工艺参数、硫磺回收装置工艺流程以及硫磺回收装置运行情况等。该工艺装置的成功应用，对我国天然气行业硫回收技术的发展具有参考价值。

Application of Clinsulf-Do Technology for Sulfur Recovery in Changqing Gas Field

The First Gas Purification Plant of Changqing gas field imported a set of sulfur-recovery unit with Clinsulf-Do technology from German Linde Company to process the sour gas coming from the desulfurizing unit(s) with MDEA solution. The sulfur-recovery unit was put into operation in May 2004, and has been running well. The sulfur-recovering rate of the unit reaches above 90%. The tail gas discharging from the unit meets the relative environmental emission standards made in China. The brief introduction of the sulfur-recovery unit with Clinsulf-Do technology, the main technical parameters, the work flow and the running status etc. of the unit are described. The successful application of the unit provides reference for the development of sulfur-recovery technology in Chinese gas industry.
