Abstract:
1. A compact sulfur recovery system comprising a plurality of components in a generally upward serial fluid flow arrangement, said plurality of components comprising: a catalytic partial oxidation reaction zone capable of withstanding temperatures up to about 2,700° F. (1,482° C.); a first temperature-control zone; a first Claus catalytic reaction zone; a second temperature-control zone; a first vapor-liquid sulfur separation zone; a first liquid sulfur outlet; and a first effluent gas outlet, said system configured to deter the accumulation of liquid sulfur in said first Claus catalytic reaction zone, wherein said catalytic partial oxidation reaction zone, said first temperature-control zone, said first Claus catalytic reaction zone, said second temperature-control zone, and said first vapor-liquid sulfur separation zone are contained in a primary structure and arranged substantially vertically in the sequence given from below to above.
