Resumen:
Abstract In this work, a multiperiod Mixed Integer Nonlinear Programming (MINLP) model is proposed for the scheduling of parallel furnaces shutdowns in an ethylene plant. The entire plant has been modeled through linear and nonlinear functions. Furnaces decaying performance is represented through coils internal roughness and heat load to furnaces, which are linearly dependent on operation time. Two sets of binary variables are associated to shutdowns and time dependent variables. The model determines not only the optimal shutdown schedule, but main plant operating variable profiles throughout the time horizon and the inventory management to satisfy time varying product demands
