摘　　要：采用CPA方程模拟了水、醇、烃多组分体系气液液三相平衡,与实验数据比较后可知,CPA方程能够较好地预测极性组分PVT特性和相平衡。并把CPA方程应用于汽提冷甲醇天然气脱水工艺的模拟计算,为工艺设计提供了必要的参考数据。The vapor-liquid-liquid phase equilibria of multi-component system of water, methanol and alkane were simulated with CPA equation. It shows that CPA equation can be used to calculate the PVT properties and phase equilibria of polar components by comparing the calculated results with experimental results. Additionally, CPA equation was used to simulate the dehydration process of natural gas with chilled methanol distillation and provide reference data for the design of process.
