These units operate in a combination of batch and continuous processes to generate multiple product grades from the same raw material. Integrating all these units creates a challenging optimization problem characterized by non-linearity, non-convexity, and discontinuity. Solving such a problem is exceedingly difficult without simplifying the model to a linear form or assuming fixed base oil yields for each grade. However, the Differential Evolution optimization method offers a solution to this problem. By employing Differential Evolution optimization, it becomes possible to solve the problem while considering the model's complexity and without making simplifications. This approach has the advantage of accommodating changes in the feedstock, particularly its composition, in order to determine the optimal operating conditions for maximizing yields. The effectiveness of this method has been demonstrated through successful testing using actual plant data. © 2024 IEEE. date: 2024 type: Conference or Workshop Item type: PeerReviewed identifier: Mohd Fadzil, M.A. and Zabiri, H.
