Abstract:
A process for removing sulfur from a gas stream is provided in which a plurality of reactor units, each comprising a condenser and reactor, are selectively operable under Claus reaction and cold bed adsorption conditions. The arrangement of reactor units within the plant is periodically changed following a front-middle-back sequencing scheme. This ensures that the final reactor unit in the series utilizes fully cooled catalyst which is most efficient for operation under cold bed adsorption conditions. In addition, the condenser of the final reactor unit in the series operates at or below the freezing point of sulfur thereby permitting even greater sulfur recovery.
