Based on the corrosion resistance evaluation monitoring and prediction of risk management

Long period operation risk assessment technology is the corrosion of crude oil evaluation system based on risk management, to improve the level of corrosion of oil refining enterprise management to lay the solid foundation. Device runs for a long period of time, is bound to equipment pipeline corrosion thinning, dirty jams damage of valve sealing failure, equipment and so on increase, in order to improve the equipment operation status and the economic index of technical renovation need to device, increase the risk of safety in production. Prison detection based corrosion data management system development and application of risk assessment technology has important practical significance to the safety in production.

At present, according to the design selection guidelines, McConomy curve, NACE and API standards for flash system devices and sulfur pipeline corrosion and acid corrosion in accounting. By entering the sulfur content of crude oil, acid value, medium temperature, pressure, corrosion related parameters to carry out the adaptability evaluation, determine the corrosion circuit, find the device area of weak corrosion and predict the corrosion rate. Through corrosion prediction evaluation, the pipeline risk grading equipment, put forward specific monitoring operation plan, issued a complete corrosion prediction assessment. Supported by real corrosion monitoring data, the establishment of expert diagnosis module, the possibility of risk of the equipment and pipelines are assessed quantitative values, know as soon as possible, to ensure long period safe operation of the device.
