Abstract
Provided is a process that may comprise cooling an engine exhaust emissions comprising SOx on a vehicle that may come from an engine. The cooled engine exhaust emissions comprising SOx may be passed to one or more absorption units. The SOx may 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 SOx. The absorbed SOx may be desorbed, followed by forming one or more SOx product from the desorbed SOx. The one or more SOx product may be unloaded to an off-vehicle facility.
Claims19
A process, comprising:
- cooling engine exhaust emissions comprising SOx on a vehicle, where the vehicle has an engine providing the engine exhaust emissions;
- passing the cooled engine exhaust emissions comprising SOx to one or more absorption units;
- extracting the SOx from the engine exhaust emissions with a sorbent supported on solid porous media in the one or more absorption units on the vehicle so as to form an absorbed SOx;
- desorbing the absorbed SOx so as to form a desorbed SOx on the vehicle;
- forming one or more SOx product from the desorbed SOx on the vehicle, where the one or more SOx products is a pressurized SOx gas stored in a storage tank;
- and
- unloading the one or more SOx products from the vehicle to an off-vehicle facility.
A process, comprising:
- cooling engine exhaust emissions comprising SOx on a vehicle, where the vehicle has an engine providing the engine exhaust emissions;
- passing the cooled engine exhaust emissions comprising SOx to one or more absorption units;
- extracting the SOx from the engine exhaust emissions with a sorbent supported on solid porous media in the one or more absorption units on the vehicle so as to form an absorbed SOx;
- desorbing the absorbed SOx so as to form both a desorbed SOx and a depleted sorbent on the vehicle;
- applying a sub-atmospheric pressure source to the one or more absorption units such that the depleted sorbent is regenerated into a sorbent;
- forming one or more SOx product from the desorbed SOx on the vehicle;
- and
- unloading the one or more SOx products from the vehicle to an off-vehicle facility.
A process, comprising:
- cooling engine exhaust emissions comprising SOx on a vehicle, where the vehicle has an engine providing the engine exhaust emissions;
- passing the cooled engine exhaust emissions comprising SOx to one or more absorption units;
- extracting the SOx from the engine exhaust emissions with a sorbent supported on solid porous media in the one or more absorption units on the vehicle so as to form an absorbed SOx;
- desorbing the absorbed SOx so as to form a desorbed SOx on the vehicle;
- forming one or more SOx product from the desorbed SOx on the vehicle;
- and
- unloading the one or more SOx products from the vehicle to an off-vehicle facility, where the off-vehicle facility is a second vehicle or a second marine vessel.
A process, comprising:
- cooling engine exhaust emissions comprising SOx on a vehicle, where the vehicle has an engine providing the engine exhaust emissions, where the cooled engine exhaust emissions have a temperature in a range of from about 20° C. to about 50° C.;
- passing the cooled engine exhaust emissions comprising SOx to one or more absorption units;
- extracting the SOx from the engine exhaust emissions with a sorbent supported on solid porous media in the one or more absorption units on the vehicle so as to form an absorbed SOx;
- desorbing the absorbed SOx so as to form a desorbed SOx on the vehicle;
- forming one or more SOx product from the desorbed SOx on the vehicle;
- and
- unloading the one or more SOx products from the vehicle to an off-vehicle facility.
