PROCEDIMENTO PER LA PRODUZIONE DI UN OSSIDO DI ZOLFO CON L USO DI ARIA IN PRESSIONE

A gaseous mixture comprising an oxide of sulfur and air, is produced by introducing into a sulfur burning zone molten sulfur and pressurized air having a pressure greater than 30 psig, at least some of the pressurized air having been preheated to a temperature above the ignition temperature of the sulphur and/or the pressurized air having been dried, burning the sulphur and the pressurized air to produce a pressurized gaseous mixture of sulfur dioxide and air, and controlling the temperature at which the pressurized gaseous mixture leaves the burning zone.
