Abstract
A system for mixing ortho-xylene with an oxygen-containing gas such as air comprises an evaporator vessel fed with the gas and having a lance projecting into the gas. The lance is provided with a metal spray nozzle for injecting droplets of hot liquid ortho-xylene into the gas stream, concurrently with the direction of flow of the gas. The metal at the surface of the spray nozzle, that in use is in contact with the liquid ortho-xylene, has a high surface hardness to resist erosion, particularly by cavitation. The system is useful in the production of phthalic anhydride by the oxidation of ortho-xylene with air, whereby the risk for deflagrations is reduced. A soft metal seal is the preferred gasket between the spray nozzle and the lance.
