【摘要】 根据我国大庆、华北、胜利、孤岛、中原和克拉玛依６种主要原油及其馏分油３种蒸馏过程实测的６４组平衡闪蒸数据，实沸点蒸馏及馏程试验各２０９组实测数据，提出了适合６种油的３种蒸馏换算式２１个，及相应的６张算图，算式中除３个式子外，其余１８个算式绝对平均偏差均低于ＡＰＩ图表偏差。更多还原

【Abstract】 Correlations among true boiling point (TBP), equilibrium-fresh vaporization (EFV)and ASTM distillation curves for Daqing, Huabei, Shengli, Zhongyuan, Gudao and Kelamayi crudes aswell as their straight-run fractions were made. 21 correlation equations and 6 correlation charts were proposed. The absolute mean deviations of the temperatures calculated from most of the equations were lowerthan those of API charts.更多还原
