2 s to elemental sulfur so 2 and water wherein the reaction is these very hot gases and vapors are cooled down in a waste heat boiler 19 and a first condenser 22 where the elemental sulfur is condensed and removed at liquid discharge conduit 25 cooling water is provided to both the waste heat boiler 19 and to the condenser 22 as shown at inlet 23 to make steam as shown at outlet 24 for use in making electricity or elsewhere in the in the claus sulfur recovery plant 10 or in the larger industrial plant that is not shown the remaining gases from the first condenser 22 are directed through the gas conduit 28 to reheater 30 where the gases are reheated and then delivered to a catalytic conversion to elemental sulfur for converting remaining h 2 s and so 2 to elemental sulfur the chemical process is generally described as follows again the process gases are cooled in the second sulfur condenser 32 so that elemental sulfur may be condensed to a liquid and removed at the second liquid discharge conduit 35 the gases are conventionally directed by a conduit 38 to further sulfur recovery steps including catalytic reactor 41 and 51 to recover liquid sulfur at discharge conduits 45 and 55 it should be noted that more thorough descriptions of a claus system may be found in many other places and there are doubtless variations known in the art this description has been presented simply to describe the improvement related.
