PROCEDIMIENTO PARA AUMENTAR LA TEMPERATURA DEL GAS DE ESCAPEPROVENIENTE DE LA PLANTA DE LAVADO DE GAS DE ESCAPE EN LA OBTENCION DE ANHIDRIDO FTALICO

摘要

The temperature of the exit gas from the gas washer in the preparation of phthalic anhydride by catalytic oxidation of naphthalene or o-xylene with air is increased by a method in which flue gas from the combustion furnace for residues is mixed with the exit gas before the latter emerges into the atmosphere.
