硫黄回收装置流程模拟及优化

Process simulation and optimization of sulphur recovery unit

硫黄回收装置外排尾气指标受多方面的影响,主要包括克劳斯反应温度、加氢反应温度、溶剂吸收系统参数等,为提高装置整体运行效率,同时兼顾尾气排放指标与装置能耗的平衡,利用Aspen Plus软件对硫黄回收装置进行建模,并利用模型对装置在不同条件下的运行情况进行模拟,根据运行结果分析各运行条件对主要工艺参数的影响,拟定装置运行的优化方案。

The index of exhaust gas discharged from the sulphur recovery unit is affected by various factors,including Claus reaction temperature,hydrogenation reaction temperature,solvent absorption system parameters,etc.In order to improve the overall operating efficiency of the unit,while balancing exhaust emission index and energy consumption of the unit,Aspen Plus software is used to model the sulphur recovery unit,and the model is used to simulate the operation of the unit under different conditions,analyze the impact of various operating conditions on the main process parameters based on the operating results,and develop an optimization plan for device operation.
