在选择吉布斯反应器的基础上,根据某专利商提供的三床层氨合成塔相关数据,修正了UniSim流程模拟软件数据库中氨的标准摩尔生成吉布斯自由能.结合某 150 kt/a氨合成塔实际生产工艺和集散控制系统(DCS)采集的现场生产数据,采用OPC通讯协议,实时更新UniSim的动态输入数据,构建了"生产数据驱动+机理模型"的数字孪生方法,达到了计算结果与生产数据的高度吻合;通过构建在线合成氨动态操作线和平衡线,实现了氨合成塔的在线评价,为即时操作决策和实时优化提供了数字化依据.
Development of Online Visualization Module for Ammonia Synthesis Converter Operation Line and Balance Line
Based on the selection of Gibbs reactor,the standard molar Gibbs free energy for ammonia formation in the UniSim process simulation software database is revised according to the relevant data of a three beds ammonia synthesis converter provided by a patent vendor.Combined with the actual production process of a 150 kt/a ammonia synthesis converter and the on-site production data collected by the distributed control system(DCS),the OPC communication protocol is used to update the dynamic input data of UniSim in real time,and a digital twin method of"production data driven+mechanism model"is constructed,achieving a high degree of consistency between the calculation results and the production data.By constructing online dynamic operating lines and a balance line for synthesis of ammonia,the online evaluation of the ammonia synthesis converter has been achieved and providing a digital basis for real-time operation decision-making and optimization.
