三级Claus硫回收装置运行中运行优化提升

IMPROVEMENTS IN OPERATION OF THREE-STAGE CLAUS SULFUR RECOVERY PLANT

介绍三级Claus硫回收装置运行中存在液硫罐底部频繁堵塞、开车过程温度调节困难以及管线腐蚀等问题,通过增设氮气加热器和过程气加热器、更换尾气蒸气夹套伴热管线以及在循环流化床锅炉设置尾气焚烧器等改造措施,优化升级,实现硫回收环保装置的安全稳定运行。

Some problems existed in three-stage Clause sulfur recovery plant have been analyzed, such as blockage frequently occurred at the bottom of the liquid sulfur tank, difficulty in temperaturere gulating during the start-up and the pipe corrosion. In order to achieve the safe and stable operation,some reforming measures were put into action by adding nitrogen heater and intermediate-gas heater, changing tail steam jacket, and adding exhaust incinerator in the circulated fluidized bed boiler.
