摘要:

针对MCRC硫磺回收装置经常出现堵塞的问题,分析了中国石油西南油气田公司川中油气矿磨溪天然气净化一厂MCRC硫磺回收装置发生堵塞的原因、容易发生堵塞的环节和部位,提出了相应的预防措施。分析结果表明,为了保障装置开工率,在开、停工过程中应加强对各操作步骤及控制节点的把握；在生产运行过程中应保证对硫磺回收装置各运行参数的控制；在检修过程中应保证系统除渣效果及设备压力检测质量。 

Abstract:

Aiming at the blocking problem of the MCRC sulfur recovery unit, the blocking reasons of MCRC sulfur recovery unit in Moxi Natural Gas Purification Plant of PetroChina Southwest Oil & Gasfield Company were analyzed. The parts are likely to be blocked and corresponding prevention measures were proposed. The analysis result showed that the control of operating steps and control nodes should be strengthened during the startup and shutdown processes in order to ensure the operating rate of the unit. The control of recovery equipment operating parameters should be guaranteed during the production operation; the removal effect of the slag in system and the pressure detection quality of the equipments should be ensured during maintenance process.
