PREDICTION OF OPTIMUM SEPARATION CONDITIONS FOR SEQUENTIAL FIELD SEPARATION SYSTEM

Abstract

A study has been done for finding the optimum separators pressures of degassing stations. The

optimum operation pressures are determined by employing Constrained Rosenbrock (1966) method using the maximum API. minimum GOR and minimum B, as objective fumetions and separators pressures as the decision variables. The optumizatien of separators pressures requires equilibriom ash dculation under difterent conditions of pressures and temperatures to determine the conditions than will sied the most stoek tunk lisquid Fquilibriam flash caléulation is achieved by solving the equation of state In the carreni study.
