This patent describes a sulfur recovery plant. It comprises: at least three units connectable for sequentially receiving process gas and for removing sulfur therefrom, each unit having a Claus catalytic reactor alternately periodically operated under effective high temperature Claus conditions and periodically operated under effective cold bed adsorption conditions, each unit comprising: a sulfur condenser having a gas inlet and a gas outlet; the gas inlet being connectable by valve control in flow communication for receiving effluent process gas from one of a Claus catalytic reactor of another unit and a source of process gas from which sulfur is to be removed, optionally from a high temperature Claus reactor; a valved bypass line connecting the gas inlet of the sulfur condenser with the gas outlet of the sulfur condenser; the Claus catalytic reactor of each unit having an inlet connected in flow communication with the gas outlet of the sulfur condenser and having an effluent outlet; outlet means for connecting the effluent outlet of the Claus catalytic reactor in flow communicating with one of an inlet of at least one other unit and a tail gasoline; and means for switching each inlet sulfur condenser as a unit with a downstream reactor during operation of the plant.
