LNG接收站BOG再冷凝工艺HYSYS模拟及优化

在BOG的再冷凝工艺流程中,主要能耗来源于压缩机。为了减少BOG的压缩能耗,保障系统稳定运行,分析了BOG压缩过程压力比焓（p-H）的变化,并运用HYSYS对原有BOG处理工艺流程进行了模拟研究,由此对工艺流程和系统作了改进及优化。结果表明,改进后的工艺流程比原有工艺流程压缩机能耗降低约15.5%,最小物料比也相对减少,两者降低有利于系统的稳定运行。...

Summary:在BOG的再冷凝工艺流程中,主要能耗来源于压缩机。为了减少BOG的压缩能耗,保障系统稳定运行,分析了BOG压缩过程压力比焓（p-H）的变化,并运用HYSYS对原有BOG处理工艺流程进行了模拟研究,由此对工艺流程和系统作了改进及优化。结果表明,改进后的工艺流程比原有工艺流程压缩机能耗降低约15.5%,最小物料比也相对减少,两者降低有利于系统的稳定运行。
Bibliography:During the BOG recondensation process,the work of compressor is the main energy consumption.This paper aimed to reduce the energy consumption in BOG treatment process and ensure the stability of the system.Based on the analysis of pressure-enthalpy（p-H）variation in BOG compression process,the BOG treatment process is simulated by HYSYS.And then the process and system are optimized in this paper.The results show that the optimized system energy costs 15.5% less than the original system,and the minimal material ratio also diminishes.Both decreases in optimized system are useful for the stable operation of the system.
