Abstract
The integration of a single auxillary fixed adsorption bed into a system comprising at least two principal treater beds for the adsorption-purification of gas streams containing water vapor results in reduced capital investment and purge gas requirements. During purge desorption of a principal treater bed the effluent is recycled through a closed loop containing the auxillary bed. Regeneration of the auxillary bed is accomplished at least in part using the effluent from the treater bed during cooldown.
