Taking the ethylene steam cracking unit of a certain integrated refining and chemical enterprise as an example,it is a meaningful exploration to seamlessly integrate the production plan optimization model with the steam cracking mechanism model.This article introduces the use of nonlinear modeling technology in the production plan optimization model of ethylene steam cracking equipment,integrating the cracking furnace simulation mechanism model,and using regression tools to obtain external mechanism model XLP files suitable for the production plan optimization model.For model optimization calculation,ethylene raw material selection and cracking operation parameters can be optimized to obtain more accurate device yield calculation results,which can realize property transfer and calculation from crude oil to naphtha,improve the refinement level of enterprise planning optimization model,and provide strong support for enterprises to optimize production,reduce costs and increase efficiency.
