Abstract
An engine system includes an oxygen capture system including at least one adsorbent material, an internal combustion engine fluidly coupled to the oxygen capture system, an exhaust processing system fluidly coupled to the internal combustion engine, the exhaust processing system including a catalytic system, at least one cooler and at least one gas/liquid separator, and a carbon capture system fluidly coupled to the exhaust processing system and the internal combustion engine, the carbon capture system including a carbon dioxide condenser and a carbon dioxide storage.
Claims16
An engine system comprising:
- an oxygen capture system comprising at least one adsorbent material;
- an internal combustion engine fluidly coupled to the oxygen capture system;
- an exhaust processing system fluidly coupled to the internal combustion engine, the exhaust processing system comprising a catalytic system, at least one cooler, and at least one gas/liquid separator;
- a carbon capture system fluidly coupled to the exhaust processing system and the internal combustion engine, the carbon capture system comprising a carbon dioxide condenser and a carbon dioxide storage;
- a compressor fluidly coupled to the at least one gas/liquid separator and receiving processed exhaust from the at least one gas/liquid separator;
- and
- a second cooler fluidly coupled to the compressor and receiving the processed exhaust from the compressor;
- wherein the carbon dioxide condenser is fluidly coupled to the second cooler and receives the processed exhaust from the second cooler;
- wherein the carbon dioxide condenser produces liquid or partial liquid carbon dioxide from the processed exhaust;
- and
- wherein the carbon dioxide storage is fluidly coupled to the carbon dioxide condenser and receives the liquid or partial liquid carbon dioxide from the carbon dioxide storage and stores the liquid or partial liquid carbon dioxide.
An emissions treatment method comprising:
- receiving, by an oxygen capture system, intake air and hot exhaust;
- separating, by the oxygen capture system, oxygen from the intake air;
- receiving, by a first cooler, the oxygen from the oxygen capture system;
- cooling, by the first cooler, the oxygen to form cooled oxygen;
- receiving, by an internal combustion engine, the cooled oxygen from the first cooler;
- receiving, by the internal combustion engine, fuel;
- combusting, by the internal combustion engine, the cooled oxygen and the fuel to produce the hot exhaust;
- cooling, by a second cooler, the hot exhaust to form cooled exhaust;
- separating, by a gas/liquid separator, the cooled exhaust to form gas and a liquid;
- compressing, by a compressor, the gas to form a compressed gas;
- cooling, by a third cooler, the compressed gas to form a cooled compressed gas;
- condensing, by a heat exchanger, the cooled compressed gas and a storage gas to form a condensed cooled compressed gas;
- receiving, by a carbon storage, the condensed cooled compressed gas;
- and
- providing, by the carbon storage, the storage gas to the heat exchanger.
An engine system comprising:
- an internal combustion engine configured to provide hot exhaust;
- an oxygen absorber configured to receive intake air, receive the hot exhaust from the internal combustion engine, and provide oxygen enriched exhaust;
- a first cooler configured to receive the oxygen enriched exhaust from the oxygen absorber and provide cooled oxygen enriched exhaust to the internal combustion engine;
- a second cooler configured to receive the hot exhaust from the internal combustion engine and provide cooled exhaust;
- and
- a gas/liquid separator configured to receive the cooled exhaust from the second cooler, provide exhaust, and provide water;
- wherein the internal combustion engine is further configured to receive the exhaust from the gas/liquid separator.
