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 through a breathing mask within an exterior mask shell.

A natural gas storage facility for reducing effects of diurnal demand on a natural gas source is disclosed. The natural gas storage facility includes a guard bed system that has a heavy natural gas component storage capacity and that is operable to remove impurities from introduced natural gas, to selectively separate the introduced natural gas into a heavy natural gas component and a light natural gas component, to retain the heavy natural gas component and to release the heavy natural gas component and an adsorption bed system that fluidly couples to the guard bed system, that has a light natural gas component storage capacity, that contains a light natural gas adsorbent that is a microporous material, and that is operable to retain the light natural gas component using the light natural gas adsorbent and to release the light natural gas component from the light natural gas adsorbent.
