Examining variations of contaminants in petroleum products in Nigeria. – D. I. Egu and A. J. Ilozobhie
Hundreds of vehicles such as airplanes, cars, ships, boats, helicopters and so on and other equipments can be faulty, break down or explode due to contaminated fuel. Contaminations such as kerosene with PMS, or DPK with water, or PMS with water and so on poses a major challenge in a growing economy like Nigeria. The aim of this work includes; to experimentally determine the degree and severity of effect of contamination on characteristics of petroleum product, with regards to level of contamination and to suggest possible ways of reducing the reversible menace of contamination of our imported petroleum products. Samples of Petrol, Kerosene and Diesel were contaminated with various percentages of water at 5%, 10%, 15% and 20%. Results showed that experimental test of gasoline with varying percentages of AGO at 5%, 10%, 15% and 20% was highly contaminated with an ambient flash point while the observed common densities before contamination was 730kg/m3. The observed densities after contamination are 739kg/m3 for 5%, 746kg/m3 for 10%, 752kg/m3 for 15% and 758kg/m3 for 20%. The corrected densities after contamination gave 748.8kg/m3, 755.7kg/m3, 761.7kg/m3 and 767.8kg/m3 for 5%, 10%, 15% and 20%. However, results of experimental test on PMS contaminated with varying percentages of mixtures of 50% diesel and 50% kerosene at 5%, 10%, 15% and 20% showed that there was no flash while the contaminated densities increased from 730kg/m3 for the 4 samples to 757.7kg/m3, 759.7kg/m3, 766.6kg/m3 and 769.6kg/m3 for 5%, 10%, 15% and 20% while the observed contaminated temperatures remained the same as 260C for both observed before and after contamination. It is recommended that quick and mobile laboratory be provided to ascertain the extent of contaminated products before dispensing them out to the public.
