Crude oil blending is an important unit operation in petroleum re…ning industry. A good model for the blending system is bene…cial for supervision operation, prediction of the export petroleum quality and realizing model-based optimal control. Since the blending cannot follow the ideal mixing rule in practice, we propose a static neural network to approximate the blending properties. By input-t...
