The study focused on soil deterioration of used engine oil from auto mobile vehicles, sampling, assessing and comparing the soil characteristics of the contaminated with respect to the uncontaminated soil. Impacts of used automobile engine oil spilled on soils in Zaria metropolis with a review of remediation method was investigated. This paper look forward consequence assessment of explosion scenario with the PHAST software then provide a procedure for rerate of ME-03 for future safe servicing. Consequence of probable explosion of pressure vessel due to corrosion progress analyzed through the commercial PHAST software. The critical role of pressure vessel on oil production delayed inspection periods for more than 10 years and moreover this pressure vessel operate at 225 psi, 100 ☏ and the volume of 860ft3 liquid that consequence assessment of this object make more important. This two-phase separator (oil and gas) is one of the most critical equipment on old Nowrooz oil production platform in Bahregan district. Initial visual inspections of the test separator ME-03 shows widely scattered local thin areas at the bottom of pressure vessel. Corrosion damage might cause to failure due to leakage.

Corrosion damages risk analyzing and consequences assessment of probable failure play remarkable role in corrosion management systems. Corrosion can counted as the most threaten factor for reducing the life of equipment in oil, gas and petrochemical industries. Non-stop growth in oil, gas and petrochemical industries and dramatic impact of corrosion due to reducing the useful life of equipment need to manage risk and analyze consequences of possible accidents make more clear.
