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.
