针对石化企业炼油系统流动腐蚀失效频繁发生的现状、结合现场系统可靠性和安全性的需求,在企业现有信息化管理系统基础上,设计并开发了基于Aspen Plus技术的流动腐蚀实时专家诊断监管系统.该系统采用面向对象的设计原则,以.NET为开发平台和My SQL为数据后台,采用Visual Basic(VB)的Active X技术与Aspen Plus工艺仿真模型连接,结合Windows Communication Foundation(WCF)与.Net Remoting通信技术进行数据通讯.该系统框架可应用于多种炼油系统腐蚀监控平台的开发,以此框架开发了常压塔顶实时流动腐蚀监控平台,该监管平台能够实现装置数据的动态监测、历史数据查询、超限报警和措施指导等功能,具有有效的腐蚀防控作用.
Aiming at decreasing the flow corrosion failure happened frequently in refining system, considering the requirements of onsite system reliability and security, on the basis of enterprise's existing information system, a real-time expert diagnostic and supervision system for flow corrosion condition based on Aspen Plus technology is developed. The system uses object-oriented design principles, with .NET as the development platform and MySQL as the backend database. Using the ActiveX technology of Visual Basic (VB), and Aspen Plus, process simulation model is connected with the system. Windows Communication Foundation (WCF) and .Net Remoting techniques are used for data communication. This structure given previously can be applied to a variety of oil refining systems. An application instance in atmospheric overhead system has been developed, which can achieve the dynamic data monitoring, the query of historical data, guidance and measures of limiting alarm, with effective function in corrosion orevention and control.
