Title: PROCESS AND SYSTEM FOR SWING ADSORPTION USING AN OVERHEAD STREAM OF A DEMETHANIZER AS PURGE GAS
Abstract:
Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to remove contaminants, such as water, from the stream. As part of the process, the adsorbent bed unit is purged with a purge stream that is provided from the overhead of the demethanizer. The configuration integrates a PPSA dehydration system with a cryogenic recovery system.
