Systems and processes for reducing carbon capture emissions are described. The process involves introducing a radical species into a decarbonized combustion gas. The radical species react with residual amines or unwanted compounds in the decarbonized combustion gas, thus reducing the concentration of residual amines or unwanted compounds in the exhaust gas. The system includes a carbon capture absorber with non-thermal plasma generator configured to provide radical species reducing the concentration of residual amines or unwanted compounds in the exhaust combustion gas.

A self-rescuer device comprises an intake pump that creates a gas stream. The gas stream enters a first sieve that separates carbon dioxide, carbon monoxide, and oxygen from the gas stream to create a mixture. The remaining gas stream flows to a second sieve that separates nitrogen from the remaining gas stream and vents the residual gas to outside of the self-rescuer device through a residual output. The separated mixture is directed to a gas processor separates the oxygen from the mixture. A nitrogen storage canister coupled to the separated output of the second sieve stores the separated nitrogen, and an oxygen storage canister coupled to the separated output of the first sieve stores and concentrates the separated oxygen until a purity threshold is met. Habitable nitrogen and oxygen are metered from their storage canisters and supplied to a user of the device through a breathing mask within an exterior mask shell.

One embodiment of the present invention sets forth a technique for operating an oxygen concentrator. The technique includes measuring a product gas within an oxygen concentrator to produce a product gas measurement, and determining that an output of the oxygen concentrator is fluidly connected to a respiratory ventilation device based on the product gas measurement. The technique further includes, in response to determining that the oxygen concentrator is fluidly connected to the respiratory ventilation device, determining that the output of the oxygen concentrator does not meet a supply gas requirement of the respiratory ventilation device and, in response to determining that the output of the oxygen concentrator does not meet the supply gas requirement, adjusting a control output in the oxygen concentrator to modify operation of the oxygen concentrator.

Embodiments of gas concentrating systems and methods are provided. In one embodiment, the system includes, for example, a plurality of modules connectable and disconnectable from each other to thereby adjust the (gas) capacity and modality of the connected system. In this manner, a user need not maintain one system for on the go (ambulatory) scenarios and a wholly second system for stationary (e.g., at home) scenarios. The systems and methods further provide the ability to gradually upgrade the system capacity consistent with the user's lifestyle and medical needs.

A method of using the natural gas storage facility to reduce the effect of diurnal demand on a natural gas source includes introducing natural gas into the natural gas storage facility, separating the natural gas into a heavy natural gas component and a light natural gas component, and retaining the components during a non-peak period of demand. The natural gas storage facility includes a guard bed system and an adsorption bed system. The method also includes releasing the heavy and light natural gas components, mixing them into a released natural gas component product and introducing it to the natural gas source during a peak period of demand.

A device and a method produces fertilizer from the exhaust gases of a production system, for example a system for producing cement. The exhaust gases are completely converted such that the exhaust gases are not released into the environment. For this purpose, the exhaust gases are introduced directly into the device from the production system. Exhaust gases such as NO.sub.x and/or SO.sub.2 are first oxidized in the device and then reprocessed into NH.sub.4NO.sub.3 or (NH.sub.4).sub.2SO.sub.4. CO.sub.2 is reprocessed into NH.sub.4HCO.sub.3 in the device while nitrogen is converted into ammonia, and the ammonium, among others, is used to produce NH.sub.4HCO.sub.3 from CO.sub.2.
