A Novel Optimization Approach for H2S Expulsion from Crude Oil

Reza Vaezi, Hossein Atashi and Farshad Farshchi Tabrizi
Abstract—Equilibrium model approach has not been used for simulation of stripping towers as the trays of those towers are non- Equilibrium in real service conditions. This paper pursues an effective approach for simulating a cold stripping tower with new trays of centrifuges by applying Equilibrium model through Aspen plus software. In this paper, Peng Robinson (PR) equation has been used as equation of state (EOS) and vaporization efficiency of components in order to change the conditions of trays from Equilibrium to non-Equilibrium. Experimental results arisen by cold stripping tower situated at Lavan Island in Iran were compared with the results of simulation in order to validate efficiency of the proposed simulation approach. Topics like process convergence and analyzing the effective parameters on reduction of H2S and optimizing of the process have been considered in this paper. The performance of the tower improved considerably by fulfillment of operational optimized conditions and reducing amount of H2S in oil from 175 to 136 ppm .
