Dependence of TBP (true boiling point) curve for oil on the method for determining the fractional composition

The subject of this study is the study of methods for determining the fractional composition of oil. The purpose of this work is to assess the influence of the method of determining the fractional composition on the oil TIC on the example of the Salymskoye field. This article describes the comparative results of determining the fractional composition of the oil of the Salym field, obtained by three different methods: atmospheric vacuum distillation, the Engler method, simulated distillation in a gas chromatographic column. The results obtained show which currently depends on the goals and objectives is a more effective method for the study of heavy oils, oil residues and petroleum products.
