AbstractThe study reported herein is concerned with the use of a nonlinear programming technique to improve the operation of an alkylation unit at an oil refinery. It involves the determination of a new set of operating conditions, which maximize daily profit and still satisfy the various constraints imposed by reaction characteristics , equipment limitations, and quality specifications. A mathematical model of the alkylation operation is first acquired. The model embodies all the pertinent information of the unit, which, when programmed on a digital computer, can predict the unit's behavior from both engineering and economic aspects, The problem is solved by first transforming it into a sequence of unconstrained ones, using Carroll's created response surface technique (CRST). The method of steepest ascent and one-dimensional search by quadratic interpolation are then applied to find the optimal set of operating variables, using a digital computer . Economic advantage is indicated between the final solution and the present operating conditions. Conclusions are made about the advantages of the approach, the applicability of the results to the actual operation, and the usefulness of the approach to a chemical or pterotic process in general.
