Corrosion Management and Control in the Petroleum Industry-A Case Study of Practicalities at Kaduna Refinery
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
Corrosion is preponderant in the petroleum environment because most known factors that can cause to extreme various types of corrosion of a wide range of materials are abundantly present in the physicochemical composition of crudes. Every crude oil has about the same kinds of constituent chemical types but in different proportions, so different types of crudes coupled with their processing, transportation and storage conditions can have different corrosivities to materials in different refineries. Kaduna refinery uses Nigerian crudes sometimes blended with foreign crudes to produce some fuels and chemical industrial raw feedstock. The refinery has however been experiencing maintenance problems over its years of existence. This paper is a report of field and literature surveys that attempted to lay bare the basis of the problems. The study found that the entire refinery structures or systems were well designed with corrosion consideration, and corrosion management and control institutionalized therein. Corrosion is managed and controlled in the refinery through many methods including corrosion monitoring and inspections, corrosion audit, and maintenances of all designed controls. The study nevertheless found that corrosion had been a serious problem in the refinery by contributing greatly to its costly maintenance needs, shutdowns and downtime, low production and profitability, and time to time non-availability of its products to the public. Shoddy and lack of proactive corrosion management and control of the refinery have been attributed to its maintenance needs at expensive costs. Possible ways of improving corrosion management and control in the refinery are suggested for enhancing its productivity, profitability and service delivery.
