精馏过程单变量扰动原因的智能反演

  • Key Words:精馏;;单变量扰动;;反演;;智能辨识

  • Abstract:由于精馏过程存在大量扰动,使得扰动原因难以确定,扰动量信息诊断精度难以提高,本文对精馏过程扰动问题进行了研究。以精馏塔回流量(L)、上升蒸汽量(V)、进料组成(zF)及进料量(F)扰动为例,在单变量扰动的基础上,将物理领域的反演思想应用于精馏故障诊断,结合精馏过程内嵌机理,建立了各扰动量与欧氏距离之间的反演模型,经过运算实现扰动量的定量分析。并将此方法录入规则,以便嵌入专家系统,实现智能辨识扰动原因。本文将此方法运用到高纯度的二元精馏塔中,实现了单变量扰动原因的定量辨识,证明了该方法的有效性。
