Abstract
This invention uses a fixed-bed adsorber, interchangeably called a capacitor herein, to process the product stream coming out of a regenerable adsorption system such as a temperature swing adsorption system (TSA) or pressure swing adsorption system (PSA). The fluid stream coming out of this fixed-bed capacitor will have a more uniform composition than the one entering the adsorption system or the capacitor. The fixed-bed adsorber operates in a once-through non-cyclic manner, similar to a conventional fixed bed reactor or adsorber.
Claims7
A process for treating a fluid stream comprising:
- sending said fluid stream through a regenerable adsorber to remove contaminants, said regenerable adsorber comprises two or more adsorbers wherein a product stream is produced from each of said adsorbers;
- passing the product stream from one of said adsorbers, through an adsorber capacitor and processing the product stream from only one adsorber at a time and then switching said adsorber capacitor to process the product stream from another adsorber within a cycle;
- combining the product stream from the adsorber capacitor with the product stream from all other adsorbers, and wherein said adsorber capacitor comprises a fixed bed adsorbent bed.
An adsorption system comprising:
- two or more adsorbers producing a product stream from each of said adsorbers;
- an adsorber capacitor in communication with said product stream from one of said adsorbers at a time, wherein said adsorber capacitor is configured to dampen a product peak composition before said two or more adsorbers require regeneration;
- and
- a product stream line from the adsorber capacitor in communication with the product stream from all other adsorbers, wherein said adsorber capacitor comprises a fixed bed adsorbent bed.
