长庆气田第一净化厂从德国Linde公司引进了一套采用ClinsulfDo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ClinsulfDo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。
Changqing gas field first purification plant from Linde, Germany introduced a set of ClinsulfDo process using sulfur recovery unit for the treatment of acid gas produced by the MDEA solution desulfurization unit. The plant was put into operation in early May 2004, production and operation in good condition, the actual sulfur recovery rate of 90% or more, the device exhaust emissions have reached the relevant national emission standards. To this end, an overview of the ClinsulfDo sulfur recovery unit, the main process parameters of the unit, the technological process of the sulfur recovery unit and the operation of the sulfur recovery unit are introduced. The successful application of the process plant has a reference value for the development of sulfur recovery technology in China’s natural gas industry.
