MODIFICATION OF THE RIAZI’S METHOD FOR PREDICTION OF DISTILLATION CURVES FOR OIL AND PETROLEUM FRACTIONS

Abstract

The analysis of modern methods for prediction of distillation curves for oil and petroleum fractions is carried out. Modification variant of Riazi's method is offered. The offered modification variant provides increase of accuracy of prediction of the initial boiling point and the final boiling point and also intermediate points in the whole boiling range. Algorithms and calculation program are developed. The comparative analysis of results of prediction of distillation curves for various crude oils and petroleum fractions, received with using of discussed methods, including techniques, used in avowed foreign software products, is made.
