Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Chemical Engineering

This research work introduces a feasible optimization simulation tool for optimization of continuous variables to the whole plant that includes fractionation section with multi-component feeds, pumps, heat exchangers and compressors rather than quite a few individual units (not complete plants) that was studied before. The goal of this research work is to establish firstly a steady state model for a new saturated gas plant that exists in a certain oil refinery plant to be compatible with two different modes (design mode and future mode) to produce LPG and Stabilized Naphtha. The chief goal of the present work is to introduce lastly an interface which facilitates the interaction between aspen HYSYS ® and MATLAB® for evolving an optimization-simulation tool which can stand on the optimum operating conditions. Sensitivity analysis study should be accomplished before and after optimization on the steady state model to enhance adequacy of the results in terms of maximum C4 recovery and minimum total annual cost
