ABSTRACT:
In the Claus process for the production of sulfur a gas stream containing ammonia and hydrogen sulfide is treated to form a gas containing hydrogen sulfide and virtually no ammonia and a second gas which contains ammonia and is virtually free from hydrogen sulfide. The two gases are separately burned in the same Claus furnace with oxygen. To produce the gas virtually free from ammonia, a partial stream of the gas containing ammonia and hydrogen sulfide is scrubbed with water with the ammonia being recovered from the water.
