Semi-Dynamic Energy Optimization of Hydrotreating Process

In this paper , we developed a semi - dynamic real - time optimization (RTO0 strategy for a hydrotreating process and performed optimization strategies on it due to minimal consumptionof energy and catalyst life time improvement . The hydrotreating process is a catalytic refining process employing a selected catalyst and a hydrogen -rich gas stream to decompose organic sulphur , ixyhen and nitorgen compounds contanied in hydrocarbon fraction.in this work kinetic and deactivation model developed and base on it energy and catalyst life time optimization was performed. deactivation and kinetic parameters were obtained from industrial plant data. energy consumption by furnace , recycle gas compressor and catalyst lifr time is defined as objective functions and optimum recycle gas rate and furnace temperature were obtained in a perioid of catalyst life . in a period of catalyst life we obtained different optimum recycle gas rate and furnace temperature. result showed that in order to gain optimum energy consumption and catalyst life there is a close relation between recycle gas flow and furnace temperature in a periiod of catalyst life time .
