An exhaust gas carbon dioxide capture and recovery system that may be mounted on a mobile vehicle or vessel. The system may include an exhaust absorber system, a solvent regenerator, a solvent loop, a carbon dioxide compressor, and a carbon dioxide storage tank, among other components. The system may be configured and integrated such that energy in the exhaust may be used to power and drive the carbon dioxide capture while having minimal parasitic effect on the engine.

In an aspect, a system includes a mixer configured to mix a fuel stream with a solvent to form a mixed stream, the solvent having a higher affinity for a second component of the fuel stream than for a first component of the fuel stream. The system includes a first separator configured to separate the mixed stream into (i) a first fuel fraction including the first component of the fuel stream and (ii) a mixed fraction including the second component of the fuel stream based on a difference in volatility of the first fuel fraction and the mixed fraction. The system includes a second separator configured to separate the mixed fraction into a second fuel fraction including the second component of the fuel stream and a solvent fraction.

A method for operating an oxycombustion engine system includes passing a nitrogen-depleted gas, a fuel, and a recycled exhaust gas into a combustion chamber, combusting a mixture of the nitrogen-depleted gas, the fuel, and the recycled exhaust gas, thereby producing an exhaust gas including carbon dioxide, detecting a pressure of the recycled exhaust gas passed to the combustion chamber, determining whether the detected pressure of the recycled exhaust gas is less than a configurable pressure threshold, and in response to determining that the detected pressure of the recycled exhaust gas is less than the configurable pressure threshold, increasing the pressure of the recycled exhaust gas passed to the combustion chamber.

Oxycombustion engine systems including recirculation management features

A vehicle system includes a fuel separation system, a combustion engine, and a computer control system. The fuel separation system includes one or more fuel separation units, the vehicle system is configured to recover from the fuel separation system and maintain vapor fuel fractions as vapor throughout the vehicle system, and the combustion engine is configured to receive a vapor fuel feed and a liquid fuel feed. A method for operating the vehicle system includes separating a vehicle fuel with a fuel separation system into a plurality of fuel fractions, recovering and maintaining the vapor fuel fractions as vapor throughout the vehicle system, producing a vapor fuel feed and a liquid fuel feed, and introducing at least one of the vapor fuel feed and the liquid fuel feed to a combustion engine.

Systems and methods for treating automotive vehicle emissions on board an automotive vehicle include the use of waste heat recovery, electrochemical water splitting, phototcatalytic water splitting, and selective catalytic reduction. Waste heat recovery is used to power electrochemical water splitting, or photocatalytic water splitting. Photons collected from a solar panel are used in photocatalytic water splitting, or in photo-assisted selective catalytic reduction. Hydrogen gas generated by water splitting is used in conjunction with catalytic reduction units to catalytically reduce NOx in an engine exhaust gas.

Thermal- and photo-assisted aftertreatment of nitrogen oxides

A fuel separation system includes a fuel separator configured to receive a fuel stream and separate the fuel stream, based on a volatility of the fuel stream, into a vapor stream defined by a first auto-ignition characteristic value and a first liquid stream defined by a second auto-ignition characteristic value, the second auto-ignition characteristic value greater than the first auto-ignition characteristic value; and a heat exchanger fluidly coupled between a fuel input of the fuel stream and the fuel separator, the heat exchanger configured to transfer heat from the vapor stream to the fuel stream, and output a heated fuel stream to the fuel separator and a second liquid stream defined by the first auto-ignition characteristic value.

Adjusting a fuel on-board a vehicle

Provided is a process that may comprise cooling an engine exhaust emissions comprising SOon a vehicle that may come from an engine. The cooled engine exhaust emissions comprising SOmay be passed to one or more absorption units. The SOmay be extracted from the engine exhaust emissions with a sorbent supported on solid porous media in an absorption unit on the vehicle to form an absorbed SO. The absorbed SOmay be desorbed, followed by forming one or more SOproduct from the desorbed SO. The one or more SOproduct may be unloaded to an off-vehicle facility.

Process to capture SOonboard vehicles and ships

Marine engine exhaust includes pollutants such as CO, NOand SO. An onboard system and method for the simultaneous removal of these pollutants includes obtaining seawater from the water on which the marine vessel travels, purifying the seawater to remove a portion of hard ions, concentrating the seawater to yield a concentrated brine solution, treating the concentrated brine solution with a chemical softener to yield a treated brine solution, acidifying the treated brine solution, and utilizing the acidified brine solution in a chlor-alkali process to yield sodium hydroxide. The sodium hydroxide can be used in an acid gas scrubber to remove CO, NO, and SOfrom the marine engine exhaust gas.

The present disclosure relates to a vehicle, system, and method for on-board catalytic upgrading of hydrocarbon fuels. In accordance with one embodiment of the present disclosure, a vehicle may include, amongst other things, an internal combustion engine configured to provide motive force to the vehicle, an unreformed fuel subsystem, a reformed fuel subsystem, and a fuel system control architecture. The unreformed fuel subsystem may be structurally configured to transfer unreformed hydrocarbon fuel from the on-board point-of-sale fuel tank to the internal combustion engine. The reformed fuel subsystem may be structurally configured to reform hydrocarbon fuel from the on-board point-of-sale fuel tank and transfer reformed fuel to the internal combustion engine along a reformed fuel supply pathway separated from the unreformed fuel supply pathway. The fuel system control architecture may include a reformate flow control device and a cetane rating controller. The cetane rating controller and the reformate flow control device may cooperate to deliver an upgraded hydrocarbon fuel to a combustion zone of the internal combustion engine.

The present invention provides selective extraction of sulfoxides, or sulfoxides in combination with sulfones, from hydrocarbon mixtures containing these compounds. A significant advantage of the invention is that oxidation products resulting from oxidative desulfurization of hydrocarbon feedstocks are selectively extracted with minimum co-extraction of non-oxidized products such as valuable hydrocarbon fuel components.
