基于HYSYS的天然气轻烃回收仿真及优化

Simulation and optimization of light hydrocarbon recovery based on HYSYS

使用HYSYS建立了轻烃分馏系统的仿真模型,并通过对比模拟数据与实际运行数据,验证了物性参数和模型的可靠性。最后,利用HYSYS对轻烃分馏系统进行模拟优化,提出了增加缠绕管换热器的换热面积、膨胀机取代J-T阀,以及进一步改进换热网络的建议,从而在不增加能耗的前提下可以大幅度提高轻烃产量。

Hysys is used to establish the simulation system of the light hydrocarbon separation process.The reliability of the model is validated by the comparison of the simulation result and the plant data.The simulation and optimization of the light hydrocarbon separation process based on HYSYS is conducted.Some suggestions have been proposed,such as increasing the area of the spiral heat exchanger,replacing J-T valve with the expander,further improving the heat exchanger networks,and so on,to significantly improve the yield of light hydrocarbon without increasing the energy consumption.
