摘要
基于某厂克劳斯硫回收装置,对影响克劳斯硫回收率的因素进行分析,发现反应温度、酸气组成、催化剂、工艺及设备等因素对硫回收率产生重要影响;提出了改进措施来提高克劳斯硫回收装置的回收率,包括:①使用主、副调节阀减小酸性气流量变化的影响;②应用在线分析仪,控制反应计量比;③采用预热空气和酸性气等方法处理含NH3酸性气;④选用性能好的催化剂;⑤调节高温掺合阀开度,控制一级转化器操作温度;⑥采用过程气换热器加热,通过旁路来控制二级转化器操作温度。
The factors that affected the yield of the sulphur recovery were analyzed based on a Claus sulfur recovery unit, the results showed that reaction temperature, sour gas composition, catalyst, process and equipment affected the yield substantially. Some optimizing measures were put forward to improve the yield, which included： ① using master and auxiliary controlling valve to lower the influence of sour gas flow rate variation; ② using on-line H2S/ SO2 ratio analyzer to control the proportion of reactants, ③ preheating air and sour gas to deal with the sour gas containing ammonia; ④ selecting high-performance catalyst; ⑤ regulating high-temperature mixing valve to control operating temperature of primary converters; ⑥ using process gas heat exchanger to heat and control the operating temperature of secondary converters through the bypass.
