计算机技术在液化石油气密度和蒸汽压分析中的应用

Application of computer technology in measurement of density and steam pressure of liquefied petroleum gas

本文介绍了液化石油气样品按SH/T0230—1992《液化石油气组成测定在(色谱法)》标准测定组成后(?)据GB/12576—1997《液化石油气蒸汽压和相对密度及辛烷值计算法》标准的算法,利用计算机技术对所测得液石油气的组成进行转换计算,继而快速准确计算出液化石油气的密度和蒸汽压。

It were introduced in this article that the density and the steam pressure of liquefied petroleum gas (LPG) could be quiekly and accurately calculated through the compositions of liquefied petroleum gas be transformed in use of computer technology according to algorithm of the standard of GB/T 12576—1997'the calculating method of steam pressure and relatively density、octane number of liquefied petroleum gas (LPG)'after the compositions of liquefied petroleum gas (LPG) were measured according to the standard of SH/T 0230—1992'the determination method of the compositions of liquefied petroleum gas (LPG) (chromatography)'.
