Abstract: Provided are apparatus and systems for performing a swing adsorption process. In particular, the method and system involves swing adsorption processes and systems designed to lessen the temperature, pressure and product stream composition fluctuations in the adsorption step of a swing adsorption process, particularly involving preparation of the adsorption bed unit using feed stream cooling in conjunction with splitting the cooled feed stream to the adsorption bed units during adsorption steps while staggering the timing of back-to-back adsorption steps in the swing adsorption process. The process may be utilized for swing adsorption processes, such as rapid cycle TSA and/or rapid cycle PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.
