Abstract
An apparatus and method for producing sulfur comprises a vessel containing a plurality of spaced-apart channels each having an upstream end communicating with an upstream manifold and a downstream end communicating with a downstream manifold. Each channel comprises a single, continuous, uninterrupted conversion stage terminating at the downstream channel end. A first mixture, of SO and air from the sulfur burner, is introduced into the upstream manifold and flows as a stream through each of the channels where the stream is cooled and the SO is converted in the conversion stage to SO to produce, at the downstream channel end, a second mixture consisting essentially of SO and air. The first mixture is not cooled between the sulfur burner and the converter. The stream flowing through the conversion stage is maintained at a temperature which sustains conversion of SO to SO , without diluting the stream with a cooling fluid or diverting the stream outside the channel contained in the converter vessel.
