摘要: Abstract A novel short-term planning model of the ethylene plant that incorporates operating variables and energy utilization in both thermal cracking down-stream process is proposed to explore potential for increasing production margin reducing losses. multi-period mixed-integer nonlinear programming (MINLP) formulated attain scheduling parallel furnaces distribution overall plant, along with determination key operation involving coil outlet temperature (COT) coke deposition. The behavior product yields formation terms varying COT profiles investigated enhance profitability whole plant. real industrial example exploit performance model. results show integrated approach attains an improvement profit achieves significant enhancement savings, compared original optimization approach.
