炼化装置腐蚀监控分析系统设计及应用

Design of a corrosion monitoring and analysis system for use in refinery units

为了全面、实时掌握生产系统中的腐蚀状况,了解腐蚀因素,针对炼化装置的腐蚀现状,通过对炼化厂现有装置中的物料化学分析、设备的定点测厚及在线监测等数据进行综合管理和评定,设计并开发了一套具有腐蚀预警、剩余寿命趋势分析及报警管理等功能的一体化管控软件,实现了炼油厂装置的腐蚀状况监控和监测数据的集成和管理。

A corrosion monitoring data network has been designed and used to develop a corrosion monitoring and analysis system platform for refinery units,in order to monitor the corrosion status of the production system and follow the corrosion factors in real time.The monitoring system evaluates the data from chemical analysis of the materials in the existing equipment of the refinery,fixed-point thickness measurementss,and on-line monitoring of the equipment.An integrated management and control software platform with the functions of corrosion warning,residual life trend analysis and alarm management has been obtained.Real-time monitoring and unified management of corrosion status and uploaded data has been accomplished in a refinery in the Lanzhou Petrochemical Company of PetroChina.
