摘要:
A combustion system and process of operating the combustion system incorporating an electrostatic precipitator, an optional flue gas desulfurizer, and a temperature swing adsorptive gas separator, for post-combustion emission abatement is provided. A very low pressure steam stream may be employed as a first regeneration stream for the temperature swing adsorptive gas separator where the very low pressure steam stream may optionally be recovered from, a very low pressure steam turbine or an auxiliary boiler. A fluid stream at a suitable temperature for regeneration of at least one adsorbent material in the temperature swing adsorptive gas separator may be employed as a second regeneration stream where the fluid stream may optionally be recovered from an electrostatic precipitator, an oxidant preheater, or an auxiliary heater.

The method for separating a fluid mixture comprising at least first and second fluid components comprises; admitting fluid mixture into an adsorptive separation system comprising at least one parallel passage adsorbent contactor structure (102), the contactor structure comprising a plurality of substantially parallel fluid flow passages (110) oriented in a first axial direction between an inlet end (104) and an outlet end (106) thereof; and at least one axially continuous axially thermally conductive adsorbent material; admitting the fluid mixture into the inlet end (104) of the parallel passage adsorbent contactor structure to flow towards the outlet end (106) in the first axial direction; adsorbing at least a portion of the first fluid component on the adsorbent material; transferring heat from a heat of adsorption of the first fluid component on the adsorbent material along the contactor structure in a second axial direction towards the inlet end (104) and opposite to the first axial direction during the adsorbing; recovering a first product fluid depleted in first fluid component relative to thefluid mixture from the outlet end (106); desorbing at least a portion of the first fluid component from the adsorbent material by heating the latterl; transferring the heat of adsorption along at least a portion of the adsorbent material in either of the axial directions to provide at least a portion of the heat of desorption of the first fluid component during desorbing; and recovering a desorbed second product fluid enriched in the first fluid component from the inlet end (104) and/or the outlet end (106).
摘要:
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 an adsorptive gas separation system contactor containing adsorbent material; adsorbing a portion of carbon dioxide; recovering a first product stream depleted in carbon dioxide for release or use; desorbing carbon dioxide from the adsorbent material and recovering a desorbed second product stream enriched in carbon dioxide for sequestration or use; admitting a conditioning and/or desorption fluid into the contactor and desorbing a second portion of carbon dioxide to recover a carbon dioxide enriched conditioning stream; and recycling a portion of the carbon dioxide enriched conditioning stream to an inlet of fuel combustor to pass through the fuel combustor for combustion.
