Revised kinetic scheme for thermal furnace of sulfur recovery units

Abstract

reserved3A revised, detailed kinetic scheme for the pyrolysis and oxidation of sulfur compounds is proposed and contextualized to thermal furnace of sulfur recovery units. The kinetic scheme differs from the literature schemes since its kinetic parameters accounts fo r the presence of light hydrocarbons, ammonia, and other species usually present in the feedstock of industrial sulfur recovery units. The scheme is validated on the literature as well as industrial data acquired from more than 10 different Claus processes.Flavio Manenti; Davide Papasidero; Eliseo RanziManenti, Flavio; Davide, Papasidero; Eliseo, Ranz
