Composition and Characteristics of
Crude Petroleum
A Brief Review
Crude Petroleum
A Brief Review
GENERAL
Crude oils are complex mixtures of a vast number of hydrocarbon compounds. Properties of crude petroleum vary appreciably and depend mainly on the origin. In this chapter, the chemical composition of the crude oils is viewed, including the hydrocarbon series as well as the nonhydrocarbon compounds. Physical methods generally used for indentifying types of crude oils are described next. Characterization and classification of crude oils based on correlation indexes and crude assays are presented, followed by a comparison between some of the well-known types of oil.

CRUDE OIL COMPOSITION
The raw material that we deal with—referred to as crude petroleum—is, by definition, the naturally occurring rock oil produced as was explained in Chapter 1. In general, composition of crude oil may be studied by two methods:

1. Chemical approach
2. Physical methods
Chemical composition describes and identifies the individual chemical compounds isolated from crude oils over the years. Physical representation, on the other hand, involves considering the crude oil and its products as mixtures of hydrocarbons and describing physical laboratory tests or methods for characterizing their quality.
