Situation models correction for real-time processes control based on simplified algorithm

The paper discusses the issues of situation models application for technical and economic values calculation for the purpose of oil refining and petrochemistry processes real-time control. The analysis conducted is of influence of unmeasured and measured (process mode parameters) feature variables, such as catalyst activity, feed data on the model parameters is conducted. It is shown that at the change of the unmeasured feature variable the situation models with linear structure can be adjusted by means of absolute polynomial term change for oil refining and petrochemistry processes. The conditions and algorithm of adjustment of linear situation calculation models of technical and economic values considered during normal facility operation is suggested.
