Characterization of Crude Oil from Various oilfields in Albania through the Instrumental Analysis

The characterization of the crude oils is depended on the evaluation of chemical and physical properties of pure oil by-products. Characteristics of crude oil are very important in the designing and operation of the almost every equipment in the refining petroleum industry. A petroleum fluid is defined by its thermodynamic and volumetric properties as well as by its physicochemical properties. Their behavior is modeled from experimental data in order to properly simulate the processing of these fluids during their industrial production. To achieve optimal crude selection and processing decisions is very important to have information refer to crude oil quality. This includes: the characteristics of crude oil fractions, density, the octane number, sulfur content, viscosity, etc. The aim of this study was quality evaluation of some specific crude oils extracted in Albania, by the classification range of obtained fractions during the crude oil distillation. It was indicated from our experiments that main physical properties of crude oils has been found in a close range, except the water content which has shown a fluctuation for different oilfields included in our study.
