A method of using the system of the present invention, by absorbing nitrogen from compressed air from a POC with a first bed, absorbing oxygen with a second bed, discarding unabsorbed argon from the compressed air as waste, desorbing enriched oxygen product, and providing a 99% oxygen product. A fluid supply warning and communication system, wherein a primary fluid reservoir is connected to the personal oxygen concentrator system. A method of using the fluid supply warning and communication system.

An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

A system and a method for continuously separating carbon dioxide from gas mixtures, utilizing a continuous loop of porous monoliths which support a sorbent within its pores. Continuously exposing a portion of the continuous loop of monoliths to a flow of gas mixture containing a minor proportion of carbon dioxide, to adsorb carbon dioxide from the flow. The loop passes through a sealed regeneration and carbon dioxide capture assembly located astride a portion of the loop, and which is capable of sealingly containing a monolith in relative movement through the assembly. The assembly chamber comprises a plurality of separately sealed zones, including at least one zone for purging oxygen from the monoliths, -a subsequent zone for heating the monolith to release the adsorbed carbon dioxide, and another cooling zone for cooling the monolith prior to reentering the adsorption portion of the loop where it is exposed to oxygen.

A method includes providing an internal combustion engine having a combustion chamber, a piston movably disposed in the combustion chamber, and a prechamber connected to the combustion chamber via a flow port. The method further includes forcing a gas mixture from the combustion chamber through a zeolite material to the prechamber using a compression stroke of the piston, where the zeolite material filters the gas mixture to provide an oxygen rich gas into the prechamber.
