ABSTRACT:
In a Claus process sulfur recovery plant of the type having at least three reactors operated alternately under high temperature Claus conditions and under cold bed adsorption conditions, an emissions-affecting pressure surge in a low pressure steam delivery system due to a high pressure to low pressure transition in a switched sulfur condenser is avoided by providing a dedicated low pressure condenser in the process gas stream at times when switching a condenser from a high pressure to a low pressure system would otherwise cause the emissions-affecting pressure surge to occur. Recoveries are maintained at high levels and operating difficulties with a prior art plant are avoided.
