A process is disclosed for removing contaminants from an olefin stream, comprising passing the contaminated olefin stream through a first adsorbent in a thermal swing adsorption process to produce a relatively pure olefin product stream, and a regenerating gas stream containing the contaminants, passing the contaminated regenerating gas stream through a pressure swing adsorption process to yield a relatively pure regenerating gas stream, which can be redirected to the thermal swing adsorption process for regenerating the adsorbent therein. |
