A preliminary investigation has been carried out on the corrosive nature of some commercial kerosene and gas oil samples. Experimental tests were conducted on the rate of corrosion of iron and galvanized steel specimens immersed in the oil samples at temperatures varying from 200° to 260°C. The results confirmed that acidity is an important factor in corrosion of metals and that temperature is a great contributing factor. Temperature significantly increased the corrosion rates resulting in manifold increases in metal losses from 1.80 to 4.70 for kerosene samples and 1.50 to 4.20 for the gas oils indicating that kerosene was more corrosive. The results of the present work provided supporting data to the corrosion problems encountered in the oil industry. It is revealed that temperature can appreciably contribute to the corrosivity of kerosene and gas oils in burners, heat exchangers, storage tanks, and other ancillary equipment.
