【Abstract】 The works on vapour-liquid equilibrium(VLE)both in China and abroadare briefly reviewed with a description of the experimental scheme adoptedin this paper.98 data points of 7 narrow fractions of Huabei crude oil by17 sets of experiments and 181 data points of 7 norrow fractions of Shenglicrude oil by 26 sets of experiments were provided.Correlation equation ofVLE constant and saturation pressure for narrow fractions is obtained byregression for each crude.更多还原
