Abstract
Inferential analysis using neural network technology is proposed for an existing crude fractionation section of an oil refinery. Plant data for a three month operation period is analyzed in order to construct various neural network models using a backpropagation algorithm. The proposed neural networks can predict various properties associated with crude oil productions. The simulation results for modeling Naphtha 95% cut point and Naphtha Reid vapor pressure properties are analyzed. The results of the proposed work can ultimately enhance the online prediction of crude oil product quality parameters for crude fractionation processes.
