Lesson 2 Overview
Video: FSC 432 Lesson 2 (2:27)
Physical properties and composition of crude oil provide critical information for the optimum operation of a petroleum refinery. This information does not only help predict the physical behavior of crude oil in refinery units, but also gives insight into its chemical composition. Therefore, the physical properties can be related to chemical properties of crude oil and its fractions and the characteristics of the resulting refinery products. The most important properties of crude include density, viscosity, boiling point distribution, pour point, and the concentration of various contaminants.
By the end of this lesson, you should be able to:
- define the significant properties of crude oil, including density, viscosity, average boiling point, sulfur, and salt content;
- understand the significance of crude oil properties in terms of refinery objectives, and describe crude oil assay;
- define and interpret the classification factors (Watson, UOP, VGC, and BMCI) as they relate to the hydrocarbon composition of crude oils;
- calculate average boiling points for crude oils using different averaging techniques and differentiate Watson and UOP characterization factors;
- analyze the elemental composition of crude oils and outline ternary classification of crude oils with respect to hydrocarbon composition, i.e., aromatics, paraffins, and naphthenes;
- assess the use of ternary classification of crude oils to estimate the refinery product yields.
