Knowledge of temperature dependence of liquid viscosity plays an important role in a variety of engineering problems in oil and gas transportation. In this work an experimental database was established, which consists of kinematic viscosity for several petroleum fractions in kerosene and gas oil ranges. A new correlation was developed to predict the effect of temperature on Kinematic Viscosity of petroleum fractions of a wide boiling range from 30 to 200 C. This correlation is based on the correlation of viscosity of pure hydrocarbons that had been developed by Mehrotra (1995). Fitting parameters have been evaluated for 235 experimental data points from 31 true boiling point fractions of Libyan crude oils and for 144 data points Arab heavy, Arab medium, and Arab Berri crude oils. In addition, fitting parameters have also been evaluated for both Libyan and Arabian and other world crude-oil fractions. The proposed correlation fits the kinematic viscosity data with an overall average relative error of 2.7 % for the 33 Libyan crude oil fractions and 2.4 % for the 167 Arabian crude oils fractions, and 3.0 % for the 35 other world fractions.

Corrosion is a severe matter regarding the most of metal using industries such as the crude oil refining. The formation of the oxides, sulfides or hydroxides on the surface of metal due to the chemical reaction between metals and surrounding is the corrosion that  highly depended on the corrosive properties of crude oil as well as the chemical composition of ferrous metals since it was expected to investigate the effect of Murban and Das blend crude oils on the rate of corrosion of seven different ferrous metals which are used in the crude oil refining industry and investigate the change in hardness of metals. The sulfur content, acidity and salt content of each crude oil were determined. A series of similar pieces of seven different types of ferrous metals were immersed in each crude oil separately and their rates of corrosion were determined by using their relative weight loss after 15, 30 and 45 days. The corroded metal surfaces were observed under the microscope. The hardness of each metal piece was tested before the immersion in crude oil and after the corrosion with the aid of Vicker’s hardness tester. The metallic concentrations of each crude oil sample were tested using atomic absorption spectroscopy (AAS). The Das blend crude oil contained higher sulfur content and acidity than Murban crude oil. Carbon steel metal pieces showed the highest corrosion rates whereas the stainless steel metal pieces showed the least corrosion rates in both crude oils since that found significant Fe and Cu concentrations from some of crude oil samples. The mild steel and the Monel showed relatively intermediate corrosion rates compared to the other types of ferrous metal pieces in both crude oils. There was a slight decrease in the initial hardness of all the ferrous metal pieces due to corrosion.
