ABSTRACT

Refining industry handles highly volatile Hydrocarbons from crude oil to light gases or heavy products. Operation of refinery units while producing useful products also causes deterioration / damage to various process equipment and piping by degradation mechanisms. The design codes and standards do not address equipment deterioration while in service and that deficiencies due to degradation or from original fabrication may be found during subsequent inspections. The root causes of deterioration could be due to inadequate design considerations including materials selection and design details or the interaction with aggressive environments/conditions that the equipment is subjected to during normal service or during transient periods.

Therefore operation of process units within a defined Integrity Operating Window (IOW) is necessary to establish and maintain a controlled process environment which would enable feedstock to be converted into products in a safe environmentally responsible manner without upsets and unplanned shutdowns. In its broadest context the IOW of a process unit can be defined as the set of boundary operating conditions within which parameters must be routinely controlled to ensure safe reliable operation.

Keywords: corrosion degradation mechanisms Integrity Operating Window (IOW) operating parameters corrosion loop target range.

To ensure the safe operation of a gas processing plant, monitoring the Critical Process Variables (CPV) against the Integrity Operating Window (IOW) is a key element for compliance with the corrosion management framework. This paper is the operator’s experience in setting up the IOW management system in a gas processing plant and benefits gained.

At the project phase, the main responsibility of a corrosion engineer is to develop Corrosion Management Program (CMP) and establish a corrosion control strategy for specific individual units. A well-designed Corrosion Management Program is the most useful material not only to prepare a corrosion control strategy, create a reliable inspection plan but also to promote corrosion knowledge management, corrosion talent development and training, integration with other disciplines such as process, operation, inspection, maintenance.
The Hydroprocessing unit is the crucial process of the refinery as high temperature and high-pressure operation conditions are in which major catastrophic accident occurs. An understanding of variables influencing corrosion in hydroprocessing units is necessary for corrosion engineers to improve the reliability, safety and environment impact associated with them. This paper describes an example of how Corrosion Management Program (CMP) and Integrity Operating Windows (IOW) are used for developing specific corrosion control strategy, corrosion knowledge sharing and integration with other disciplines to prepare customized corrosion control strategy of hydroprocessing unit in JAZAN project. The development of corrosion management strategy of Hydroprocessing is focused on the Reactor Effluent Air Cooler system corrosion control using a water-washing method.
