REGENERATION LOOP CLEAN-UP |
摘要 |
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. |

1. A process for removing contaminants from an olefin feed comprising:
a) directing said olefin feed into contact with a first particulate adsorbent bed capable of removing said contaminants from said olefin feed, and producing an olefin product containing less contaminants than said feed; b) heating said first adsorbent bed and directing a regenerating gas through the first adsorbent bed to desorb said contaminants from said adsorbent, and produce a regeneration gas effluent containing said contaminants; and c) directing said regeneration gas effluent through a second particulate adsorbent bed, so as to adsorb and remove said contaminants from said regeneration gas effluent and produce a regenerating gas product having a reduced level of contaminants than said regeneration gas effluent. |
