Power Recovery Study from Phenol Wet Air Oxidation Process

Abstract

Several studies have investigated the recovery of the heat produced by the highly exothermic reaction of oxidation in Wet Air Oxidation processes (WAO) by the estimation of effluent concentrations from which the process becomes autotherm, but little works has been devoted to the recovery of electricity and especially the exact calculation of the organic pollutant concentrations from which energetic self sufficiency is achieved by the process. In this present work, we are interested in the recovery of energy in the form of heat and electricity consumed and produced by the process in the treatment of water polluted by phenol. The objective is the calculation of the exact value of the autotherm point and also the autoelectric point in the process and the determination of the influence of operating pressure and temperature on electrical production and self-
