Abstract
A reactor unit for use in extended Claus process plants comprising three or more reactor units, each alternating between operation under high temperature Claus and cold bed adsorption conditions, comprises a sulfur condenser upstream of an associated downstream reactor which are rotated as a unit through operations in the plant. This reduces the number of condensers required. In a further aspect, a potential surge in the plant low pressure steam system is eliminated in comparison with previous similar extended Claus plants.
