天然气浅冷回收装置工艺优化

Process Parameters Optimization of Natural Gas Shallow Condensing Recovery Unit

运用HYSIM烃类工艺模拟软件,对某套天然气浅冷回收装置进行工艺流程模拟,建立了优化问题模型。研究了温度、压力对单位能耗的影响,并对装置的工艺参数进行了优化。结果表明:装置的最优工艺参数为增压机出口压力1. 24MPa,蒸发器出口温度-25℃。

The process of a shallow condensing recovery unit is simulated with HYSIM. The optimization model was established. Influences of temperature and pressure on energy consumption are studied and the process parameters are optimized. The results showed that the optimal process parameter of the compressor outlet pressure is 1.24MPa and the evaporator outlet temperature is -25℃.
