A process for purifying a fluid stream which includes an impurity and a product fluid comprising providing three adsorption zones, cycling each of the adsorption zones on stream for the adsorption of the impurity from the fluid stream in a predetermined sequence to provide a substantially uninterrupted flow of the product fluid from the adsorption zones, desorbing the impurity from each of the adsorption zones in a predetermined sequence by sequentially reducing the pressure within each of the adsorption zones sufficiently to desorb the impurity, and repressurizing each of the adsorption zones subsequent to the desorption of such adsorption zone to make such adsorption zone ready for subsequent use for on stream adsorption of the impurity. The duration of the period of desorption for each of the adsorption zones is at least as great as about the duration of the period of on stream adsorption of the impurity. The desorption of a first of the adsorption zones occurs during at least the latter portion of the period that a second of the adsorption zones is on stream for the adsorption of the impurity and during at least an initial portion of the period that a third of the adsorption zones is on stream for the adsorption of the impurity.
