It's well-known that the primary costs and losses in petroleum refining come from sudden failures of equipment. A distributed control system (DCS) supplies comprehensive information on the process and operation modes of the equipment. However, its health during operation escapes the attention of operators who continuously change process modes while controlling the process plant.
Conventional solutions such as protection or condition monitoring systems are focused on the confining of consequences, but not on preventing breakdowns. If the protection system alarms, the breakdown happens; moreover, every condition monitoring system requires interpretation by an expert, and nobody understands what should be done to prevent failure without it.
For sustainable and reliable operation, it's necessary to provide operators with timely, unbiased information on how the operation mode affects the equipment's health before a failure when early diagnostics of defects allow people to eliminate future issues at its emergent stage.
