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 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.

Dependent claims

An integrated adsorptive gas separation system for separating at least a portion of a combustion gas stream, said combustion gas stream comprising at least carbon dioxide and water components, the system comprising:

(a) a prime mover comprising an oxidant inlet, a combustion chamber and an exhaust outlet, that during operation produces said combustion gas stream;
(b) an auxiliary heat exchanger comprising an auxiliary heat exchange conduit fluidly connected to receive and heat a desorption fluid stream by a heating circuit fluidly connected to receive at least a portion of said combustion gas stream from said prime mover;
(c) a combustion gas cooler, downstream of said auxiliary heat exchanger, fluidly connected to receive said combustion gas stream from said auxiliary heat exchanger for separating and recovering at least a portion of said water component from said combustion gas stream and producing a first condensable stream and wherein said desorption fluid stream comprises at least a portion of said first condensate stream;
(d) an adsorptive gas separator comprising at least one adsorbent contactor, said adsorbent contactor having an inlet and an outlet and comprising at least one adsorbent material for adsorbing said carbon dioxide component,
wherein at least one said adsorbent contactor is fluidly connected to receive said combustion gas stream from said combustion gas cooler into said inlet of at least one said adsorbent contactor, and to adsorb at least a portion of said carbon dioxide component onto at least one said adsorbent material, and
wherein said adsorbent contactor is fluidly connected to receive said desorption fluid stream from said auxiliary heat exchange conduit to desorb at least a portion of said carbon dioxide component on at least one said adsorbent material, producing a second product stream enriched in said carbon dioxide relative to said combustion gas stream,
wherein said desorption fluid stream is admitted into said auxiliary heat exchange conduit at a feed stream at a pressure less than about 2 bar above ambient.
