高含硫天然气净化装置硫磺系统停工保护技术研究与应用

Study and application on shutdown protection of sulfur unit in purification plant for high sulfur natural gas

防止停工期间硫磺系统中所含设备严重腐蚀、Fe S和催化剂自燃及水分凝结,开展对硫磺系统停工保护的技术攻关。对气相系统作为统一系统进行密闭性试验及持续吹扫保压试验,确定最佳停工保护方法及相应工艺参数,达到对硫磺系统进行高效可靠停工保护的目的。

This paper analyses the reasons of shutdown protection for sulfur unit in high sulfur natural gas purification plant andputs forward effective measures to protect this unit.
