乙烯装置空冷设备节能降耗优化操作分析

Optimization operation analysis on energy-saving & consumption reduction of air cooling equipment in ethylene plant

在现行的乙烯装置空冷设备中,现场人员对空冷的操作上随意性比较大,没有做到精细化管理。文中以某乙烯裂解装置的空冷设备为例,通过Gambit建立网格,再利用Fluent进行空气流动形态计算得到最佳的换热状态,用于指导现场人员实际操作,达到装置节能降耗的目的。

In the existing cooling equipment of ethylene plant,field staffs has a high randomness in the operation of air cooling equipment,and has not achieved fine management. With the air cooling equipment of an ethylene cracking plant as an example,grids were established by using Gambit,and air flow pattern calculation was made by using Fluent to get the best heat exchange condition. They were used to guide the field staffs in actual operation,and the goal of plant energy saving and consumption reduction was achieved.
