【摘要】：本文通过分析典型天然气三甘醇脱水装置工艺流程,得出能耗偏高的原因,提出采用开米尔能量循环泵替代电泵充分利用高压三甘醇的压力能;用板式换热器替代管壳式换热器,提高贫液进重沸器温度,降低重沸器负荷;并通过Uni Sim软件模拟计算了节约的能耗。通过对典型天然气三甘醇脱水装置工艺流程的分析,得出能耗偏高的原因,提出三甘醇脱水装置节能设计,并通过工艺模拟计算了节约的能耗。
[Abstract]:In this paper, by analyzing the typical process of natural gas three glycol dehydration unit, causes of high energy consumption, the Khyber energy circulating pump instead of electric pump can make full use of high-pressure pressure to three DEG; heat exchangers used instead of tube shell heat exchanger, improve the lean liquid into the reboiler temperature, reduce the reboiler load; and through the Uni Sim simulation software to save energy consumption calculation. By analyzing the technological process of a typical natural gas three ethylene glycol dehydration plant, the reason for the high energy consumption is obtained. The energy saving design of the three glycols dehydration unit is put forward, and the energy saving is calculated through the process simulation.
