LPG回收系统制冷温度的模拟计算

The Simulation Calculation of Refrigeration Temperature to LPG Recovery System

文章介绍了LPG回收制冷温度的重要性,以UEP项目为模型,阐述了LPG的回收工艺流程,并通过HYSYS模拟计算,讨论了膨胀机出口压力与C3回收率、总功耗、LPG的回收量、外输气量的关系;最后通过相对收益确定最佳的LPG回收制冷温度范围。

The paper introduces the importance of LPG recovery refrigeration temperature, with UEP project for the model, expounds the LPG recovery process, and through HYSYS simulation, discusses the relations of expander outlet pressure with total power consumption, C3 recovery rate LPG recycled and sale gas volume; finally determine the optimal LPG recovery refrigeration temperature range through relative income.
