Apparatus for in-situ production of low dissolved hydrogen sulfide, degassed, sulfur from Claus sulfur recovery

摘要

A vertically oriented sulfur condenser may employ a plurality of condenser tubes arranged longitudinally within an exterior casing, a liquid sulfur reservoir at a longitudinal end of the sulfur condenser, and a condenser tube wall of at least one of the plurality of condenser tubes that protrudes into and below a liquid sulfur reservoir. A catalyst may be located within the liquid sulfur reservoir. A liquid sulfur outlet may be located at the liquid sulfur surface. A Claus process gas inlet may be proximate a first end of the plurality of condenser tubes. A first tube sheet may connect to and seal an end of the plurality of condenser tubes proximate a first end of the plurality of condenser tubes. A second tube sheet may connect to and seals with the plurality of condenser tubes and the exterior casing proximate a second end of the plurality of condenser tubes.
