摘要
水露点是天然气管道输送安全的一个重要指标。介绍了PR方程与SRK方程,利用两个方程的不同混合法则及相平衡计算,通过编写程序,计算出在相同条件下,不同方程之间计算出的水露点的差异,得出利用PR方程计算出的水露点较SRK方程计算的结果偏低。
The water dew point is an important indicatorforthe natural gas pipeline safety.Inthis article,PR and SRK equationsweredescribed. Usingmixing rules and phase equilibrium calculation of the two equations, the difference of thewater dew pointscalculatedbythetwoequations under the same conditionswascalculated.The results showthat, thewater dew pointcalculatedbythe PR equation is lowerthanthatcalculatedbythe SRK equation.
