System Identification and Modeling of Crude Oil Distillation Column

A dynamic model of a crude oil distillation column is established by identifica-tion.The process is analyzed and a description of simplified MISO System isobtained.Dynamic tests are carried out by use of P.R.B.S.and models areidentified.Several methods are compared with each other.Many results show thatthe identification of practical industrial process by simple methods is feasible andthe models have been successfully used to practical process.Some successfulmethods and experience are presented.
