摘要
在系统分析液化石油气诸组分与其饱和蒸气压关系的基础上,提出了应用气相色谱测定饱和蒸气压的新方法,应用多元回归分析建立了计算液化石油气饱和蒸气压的经验公式。计算结果表明,该方法较 ASTM D2598-73标准方法准确,并符合 GB 6602-89标准。该方法操作简单、快速、安全,可以取代常规的测定方法。
A gas chromatographic method for the determination of the saturated va-por pressure of liquified petroleum gases(LPG)was developed on the basis ofsystematically studying the relationship between LPG composition and LPGsatarated vapor pressure,and an empirical equation was derived by multipleregression analysis.Comparison between the calculated vapor pressures and theexperimental ones indicate that this method is more accurate than ASTM D2598-73 and conforms to GB 6602-89.It also shows that this methed is simple.rapid and safe,and can be used to raplace the conventional ones.
