ABSTRACT
Production planning is vital to modern refinery operation because of increasing crude prices and changing market demands. In this article LP/NLP is used to simulate the effect of change in crude types on the yields of CDU, VDU, visbreaker, feed and product blender units. Central Composite experimental Design (CCD)and Response Surface Methodology (RSM) are used to obtain a second-degree polynomial model for maximizing profitability of operation of these units.
