Development and Application of Integrated Corrosion Monitoring System in Refining Unit

Abstract

For a large part of accidents in refining enterprise are caused by equipment and pipeline corrosion. By enhancing corrosion monitoring management on process and equipment, enterprise can improve the effect of corrosion protection work, and guarantee the safe and stable operation of unit. In order to manage the on-line monitoring, on-line and manual fixed-point thickness detecting and chemical analysis of corrosion monitoring methods commonly used in refining enterprise, this paper develops the integrated corrosion monitoring system, which achieves data acquisition, data management and data analysis etc. in various types of corrosion monitoring. Based on the method of Integrity Operating Windows, and taking the circuit as the evaluation object, the integrated corrosion monitoring system can do correlation analysis to all kinds of monitoring results, and judge the root cause of the corrosion occurred from multi aspects by combining with the basic data of equipment and process, which provides guidance and basis for the enterprise decision-making on corrosion management. After more than one year of operation, the system has played an important role in finding abnormal data analysis in many times, judging corrosion position quickly, and guiding enterprises to take corresponding anticorrosion measures rapidly, which effectively prevent the safety accidents.
