Abstract
A method for partially oxidizing, in a Claus furnace, at least one gas containing hydrogen sulfide and ammonia with at least one gas rich in oxygen. The residual ammonia content at the outlet of the furnace is measured with a laser diode. Based upon this measurement, the flow rates of the ammonia containing gases and the oxygen rich gases may be modified to obtain the desired residual ammonia content.
