Description:

Refinery units need to be reliable for economic and safety reasons. A major contributor to unreliability is degradation of equipment because of operations outside of design or anticipated ranges. Tools such as RBI help prioritize inspection and maintenance resources, but they assume that operations will be in a certain range of parameters. Materials Operating Envelopes (MOEs) are real-time limits for each part of a unit with regard to corrosives, process conditions, additives, water wash, etc., such that a unit operating within the envelope experiences predictable and reasonably low degradation. To create MOEs requires extensive materials, corrosion and operations expertise. This paper discusses how MOEs are created, the increased work associated with sampling and analysis of process streams, corrosion monitoring activities, and lists examples and benefits of a MOE program.
