中文摘要：随着天然气气井的不断开采，天然气处理量不断下降，某天然气脱硫装置实际运行负荷只有设计值的50~60%，装置长期处于低负荷运行状态。利用ASPEN HYSYS对该脱硫装置进行全流程模拟，将实际运行参数与模拟数据进行比对，从中找出优化装置运行的方案，通过本次模拟发现调整贫液入塔层数及循环量、加强换热器清洗等操作对装置节能降耗、优化运行均有一定的作用。
英文摘要：With the exploitation of natural gas wells, processing volume of nature gas continued to decline，processing volume of a natural gas desulfurization unit load of only 50 to 60% of the design value, means a long period of low load operation. Using the ASPEN HYSYS simulation the process of the desulfurization unit, the actual operating parameters were compared with simulated data to find out solutions to optimize plant operation, through this simulation found that adjustment layers into the tower and circulating fluid volume, strengthen heat exchanger cleaning operation on the unit energy consumption, optimize the operation has a certain role.
