A system for treating engine exhaust gas, which engine exhaust gas has a temperature of between T1 and T2, comprises a SCR reactor for converting NOx in a medium containing the engine exhaust gas into N2 and H2O. The SCR reactor has an inlet for receiving the medium and an outlet for outputting the NOx reduced medium. A first boiler unit has an outlet for outputting boiler exhaust gas (temperature greater than T3, T3>T1) from the first boiler unit. A mixing unit mixes the engine exhaust gas with the boiler exhaust gas to produce the medium. The mixing unit has a first inlet communicating with the engine for receiving the engine exhaust gas, a second inlet communicating with the outlet of the first boiler unit for receiving the boiler exhaust gas and an outlet for outputting the medium. The mixing unit outlet communicates with the inlet of the SCR reactor.

An apparatus for capturing combustion gases includes a container defining an inner cavity configured for holding a liquid, and an exhaust end for exhausting gas. An inlet is in fluid communication with a lower portion of the inner cavity, and adapted to receive an injection of combustion gases. One or more fragmentation members are located in the inner cavity downstream of the inlet and upstream of the exhaust end, the fragmentation member configured to be immersed in the liquid of the container, to induce a fragmentation of the combustion gases passing therethough for capture of the combustion gases by the liquid. A method for capturing combustion gases in a liquid is provided.

Devices, systems, and methods for carbon capture optimization in industrial facilities are disclosed herein. An example carbon capture process involves cooling a flue gas stream using at least one gas-to-air heat exchanger disposed upstream of a carbon dioxide (CO2) absorber. Another example carbon capture process involves heating a heat medium for solvent regeneration and CO2 stripping using a fired heater and/or using at least one waste heat recovery unit.

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow-establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicle, with or without using flow-establishing devices.
