Abstract: An adsorptive gas separation process and system is provided for separating at least a first component from a multi-component fluid mixture, or specifically for separating carbon dioxide from a combustion gas stream.

Abstract: An integrated fuel combustion system with gas separation (adsorptive, absorptive, membrane or other suitable gas separation) separates a portion of carbon dioxide from a combustion gas mixture and provides for recycle of separated carbon dioxide to the intake of a fuel combustor for combustion. A process for carbon dioxide separation and recycle includes: admitting combustion gas to a gas separation system; sorbing a portion of carbon dioxide; recovering a flue gas stream depleted in carbon dioxide for release or use; desorbing the carbon dioxide from the gas separation system; admitting an oxidant stream into the gas separation system and forming a mixed oxidant stream; and recycling a portion of the mixed oxidant stream to an inlet of the fuel combustor.

Abstract: An adsorptive gas separator incorporates a stator having plurality of a fluid passages where a thermal conductivity between a plurality of fluid passages is below a threshold thermal conductivity, to reduce the transfer of heat across the stator. A stator of an adsorptive gas separator may employ a port assembly having a low thermal conductivity and a floating seal which provides for sealing of heat and a fluid stream.

Abstract: A method of adsorption allows separation of a first fluid component from a fluid mixture comprising at least the first fluid component in an adsorptive separation system having a parallel passage adsorbent contactor with parallel flow passages having cell walls which include an adsorbent material. The method provides for transferring heat from the heat of adsorption in a countercurrent direction along at least a portion of the contactor during adsorption and transferring heat in either axial direction along the contactor and/or a direction transverse to the axial direction, to provide at least a portion of the heat of desorption during a desorption step. A carbon dioxide separation process to separate carbon dioxide from flue gas also includes steps transferring heat from adsorption or for desorption along the parallel passage adsorbent contactor.

Abstract: A multi-stage adsorptive gas separation process and system for separating at least a first component from a multi-component fluid mixture employs at least a first and second adsorption stage, for reducing overall steam and energy consumption for regeneration of an adsorbent material. In the adsorptive gas separation system, a first-stage adsorptive gas separation process and separator, and a second-stage adsorptive gas separation process and separator, each employ one regenerating stream, where the regenerating streams have different regeneration mediums.

Abstract: A parallel passage fluid contactor structure for chemical reaction processes has one or more segments, where each segment has a plurality of substantially parallel fluid flow passages oriented in an axial direction; cell walls between each adjacent fluid flow passages and each cell wall has at least two opposite cell wall surfaces. The structure also includes at least one active compound in the cell walls and multiple axially continuous conductive filaments either embedded within the cell walls or situated between the cell wall surfaces. The conductive filaments are at least one of thermally and electrically conductive, are oriented in axially, and are in direct contact with the active compound, and are operable to transfer thermal energy between the active material and the conductive filaments. Heating of the conductive filaments may be used to transfer heat to the active material in the cell walls. Methods of manufacturing the structure are discussed.
