蒸汽管网智能监测系统的模拟应用

APPLICATION OF INTELLIGENT MONITORING SYSTEM FOR STEAM PIPELINE NETWORK

蒸汽管网智能监测系统可以对蒸汽管网的参数进行实时监测,并通过建立管网数学模型对蒸汽管网进行模拟计算。将该监测系统应用于中化泉州石化有限公司中压蒸汽管网,选取动力站供汽量为-30~60 t/h和30~90 t/h两种工况下对关键装置透平供汽量及进汽温度进行模拟分析,解决了部分装置透平进汽温度低的问题;提出了新增透平来消化富余蒸汽和稳定中压管网的途径,并模拟出新增透平的最佳位置在靠近催化裂化装置处,实现了整个蒸汽系统的节能优化和安全稳定运行。

The intelligent steam pipeline network monitoring system can monitor the parameters of the steam pipeline network in real time and simulate the network by mathematical model.The monitoring system was applied to the medium pressure steam pipeline network of Sinochem Quanzhou Petrochemical Co.Ltd.The steam supply and inlet temperature of the turbine of the key unit were simulated under the two working conditions of-30 to 60 t/h and 30 to 90 t/h,which solved the problem of low inlet temperature of the turbine of some units.The method of adding new turbine to digest surplus steam and stabilize medium pressure pipeline network was put forward.It was recognized by simulation that the optimal position of the new turbine is near the FCC unit to realize energy saving optimization and safe and stable operation of the whole steam system.
