摘要
首先介绍了建立某厂流化催化裂化装置(FCCU)提升管反应器部分的非线性数学模型,并选用通用模型表示不可测变量──催化剂循环量。利用非线性扩展Kalman滤波理论实时估计催化剂循环量。以一组可测参数和估计参数构成数据库,按专家经验构成了FCCU反应器子系统的故障诊断系统;该故障诊断系统可以诊断出催化剂循环中止、原料带水、反应温度控制系统失灵等故障。
Nonlinear mathematic model of riser reactor in some FCC units has been made. A general model of unmeasurable variable is used for real time estimation of catalyst flow. Fault diagnosis systemof riser reactor consists of expert experience and data-base including measurable variables and estimatedvariables, which can provide information about the case of catalyst flow, feed containing water and reactorcontrol system breakdown.
