Filed:

Aug 9, 2022

Appl. No.:

17/884383

Inventors:

- Annandale NJ, US

Ananda K. Nagavarapu - Houston TX, US

International Classification:

B01D 53/04
B01D 53/08

Abstract:

Systems and methods are provided for separation of COfrom dilute source streams. The systems and methods for the separation can include use of contactors that correspond radial flow adsorbent modules that can allow for efficient contact of CO-containing gas with adsorbent beds while also facilitating use of heat transfer fluids in the vicinity of the adsorbent beds to reduce or minimize temperature variations. In particular, the radial flow adsorbent beds can be alternated with regions of axial flow heat transfer conduits to provide thermal management. The radial flow structure for the adsorbent beds combined with axial flow conduits for heat transfer fluids can allow for sufficient temperature control to either a) reduce or minimize temperature variations within the adsorbent beds or b) facilitate performing the separation using temperature as a swing variable for controlling the working capacity of the adsorbent.

Abstract:

The disclosure generally relates to CCS sorbents, particularly for CO/HO displacement desorption process. The sorbents include an aluminum oxide support that includes two alkali metal salts impregnated on the support. The two alkali metals include a potassium metal salts and a second alkali metal salt which is not potassium. The second metal salt disrupts poisoning effects that degrade sorbent lifetime. The sorbents demonstrate improved COloadings and better HO/COratios, as well as improved stability. Compositions and methods of making are disclosed.

Abstract:

The disclosure generally relates to CCS sorbents, particularly for CO/HO displacement desorption process. The sorbent includes an aluminum oxide support and an alkali metal salt impregnated on the support, and a silicon modification of the sorbent to reduce water uptake by the sorbent and make it more hydrophobic. The silicon modification can be an organosilyl moiety added after the initial sorbent is complete, or a silica source added to the aluminum oxide structure, typically via impregnation. The sorbents demonstrate better HO/COratios. Compositions and methods of making are disclosed.

Abstract:

The disclosure generally relates to CCS sorbents, particularly for CO/HO displacement desorption process. The sorbent includes an aluminum oxide support and an alkali metal salt impregnated on the support. The support can be prepared by creating and extruding a dough to create an extrudate, which is then drying and calcined to form the support. Calcination temperatures can be between about 120 C. and 500 C., preferably about 200 C. to about 400 C. The sorbents demonstrate improved COloadings and better HO/COratios, as well as improved stability. Compositions and methods of making are disclosed.

International Classification:

B01D 53/06

US Classification:

95113, 96125

Abstract:

A rotary moving bed and process for separating a carbon dioxide from a gas stream is disclosed. The rotary moving bed can have a rotational assembly rotating on a vertical axis, and a plurality of sorbent cells positioned horizontally to the axis of rotation that fills a vertical space in the moving bed, where the sorbent cells adsorb the carbon dioxide by concentration swing adsorption and adsorptive displacement. The sorbent can be regenerated and the carbon dioxide recaptured by desorbing the carbon dioxide from the sorbent using concentration swing adsorption and desorptive displacement with steam. The gas flows in the system flow in a direction horizontal to the axis of rotation and in a direction opposite the rotational movement of the sorbent cells.
