  • Can a simulation-optimization approach be used to design crude oil distillation units?
  • This work applies a simulation-optimization approach for the design of crude oil distillation units that integrates a rigorous tray-by-tray model of the distillation unit implemented in a commercial process simulator (Aspen HYSYS v8.6) with an optimization algorithm coded in Matlab R2015a.
  • Why is crude oil distillation a challenging design & optimization problem?
  • The complex nature of crude oil distillation, coupled with the large number of degrees of freedom, poses a highly challenging design and optimization problem. Additional challenges arise due to the need to simultaneously design the complex column and address heat recovery while taking into account multiple feedstocks.
  • How is the configuration of crude oil distillation unit optimized?
  • Configuration of crude oil distillation unit to be optimized. As the methodology requires an initial feasible design, the initial stage distribution and operating conditions for Tia Juana light crude oil are adapted from the design of Chen (2008), also presented in Ibrahim et al. (2017a).
  • Can optimization-based design of crude oil distillation unit solve a mixed integer nonlinear programming problem?
  • Conclusions Optimization-based design of a crude oil distillation unit using surrogate models naturally leads to a mixed integer nonlinear programming problem that is very difficult to solve. Heat recovery needs to be considered during column design in order to account effectively for the trade-off between capital and operating cost.
  • How flexible is a crude oil distillation unit?
  • The case study chosen to demonstrate the capabilities of the proposed design methodology considers the design of a crude oil distillation unit that is flexible enough to process three specified crude oil feedstocks, and that is optimized in terms of profit margin.
  • What is the objective function of a crude oil distillation unit?
  • The objective function [f (x D, x S, x O)] employed in this work is the total annualized cost, since the aim is to identify the design alternative that minimizes both capital expenditures and operating costs of the crude oil distillation unit.
