The present invention is a method and system for collection of exhaust emissions installed in vehicles and disposal thereof, based on pollution conditions of the surrounding environment, said conditions identified either from sensors installed on the vehicles themselves, or by means of an external service, e.g. the Internet, cloud service, etc.

A novel emissions control watercraft (STAXcraft) solving a long-felt but unsolved need regarding disadvantages associated with prior-art emissions servicing watercraft, the disadvantages selected from the group, but not limited to, the use of tugboats, securing or mooring servicing watercraft to a serviced vessel, additional expenses and time-delays and inefficiencies of land-based approaches, increased toxic emissions, increased greenhouse gases (GHG) emissions, danger from falling cargo, tanker safety, alongside mooring in narrow channels preventing other OGV's to pass safely, and cargo tank emissions.

A vehicle 100 comprises a fuel tank for storing fuel, a fueling port for supplying the fuel tank with fuel, a CO.sub.2 recovery device configured to recover CO.sub.2, a CO.sub.2 collection port for collecting CO.sub.2 from the CO.sub.2 recovery device, and a single openable lid configured to cover both the fueling port and the CO.sub.2 collection port.

A combined power conversion and carbon capture and recycling subsystem including a fossil fueled oxidation unit, a physical adsorbent CO2 capture medium, rotor, motor, heater, CO2 compressor, diffuser and water storage tank. Exhaust gas from fossil fuel oxidation is scrubbed of CO2 via passage across a physical adsorbent and then released from the adsorbent via fuel oxidation waste heat. High CO2 concentration scrubber exhaust air is then compressed and fed to a diffuser which facilitates dissociation of the CO2 into water where it is temporarily stored for use in watering plants. Carbon from fossil fuel is recycled back into the environment and permanently stored as biomass by natural means of photosynthesis.

A system for mobile carbon capture, preferably including a capture module, a regeneration module, and a storage module 130. The system can optionally include a thermal control module and/or a dehumidifier. A method for mobile carbon capture, preferably including adsorbing a target species, desorbing the target species, and storing the target species. The method can optionally include pre-treating input gas, offloading stored species, and/or regenerating desiccators.

A high-pressure SCR system with venting and pressure-stabilizing for marine diesel engine, comprising an SCR reactor (10), a gas intake pipeline (20), an exhaust pipeline (30), a bypass pipeline (40), a pneumatic pipeline (50), a first auxiliary pipeline (70), and a second auxiliary pipeline (80). When the exhaust gas of the diesel engine needs to undergo denitrification treatment, the exhaust gas of the diesel engine can enter from a flue gas inlet, sequentially pass through the gas intake pipeline (20), the SCR reactor (10), and the exhaust pipeline (30), and be discharged from a flue gas outlet, the exhaust gas undergoing denitrification treatment in the SCR reactor (10). When the exhaust gas of the diesel engine does not need to undergo denitrification treatment, the exhaust gas can enter the bypass pipeline (40) from the flue gas inlet and be discharged from the flue gas outlet, the exhaust gas in the SCR reactor (10) and exhaust pipeline being pushed by compressed air entering from the first auxiliary pipeline (70) and the second auxiliary pipeline (80) to be discharged from the flue gas outlet. The present system eliminates the original inlet air pipeline, simplifying the structure of the entire system so that the entire system is more compact, ensuring thorough ventilation and reducing the amount of air consumption. Also provided is a ship.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel cooperated with exhaust gas recirculation (EGR), and a vessel including the same, in which NO.sub.x generation is reduced, which is the original purpose of EGR, while maintaining existing EGR, SO.sub.x as well as CO.sub.2, which is the representative greenhouse gas, are absorbed and converted into materials that do not affect environments, and the materials are discharged or stored as useful materials, thereby preventing corrosion of an engine and improving combustion efficiency.
