Abstract:
1. A compact sulfur recovery system comprising a plurality of components in 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 when said system is operated in a downward flow process for recovering elemental sulfur from a H 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 vertically in the sequence given.
