Abstract: A cartridge for non-cryogenically separating a gas into components includes a plurality of hollow polymeric fibers, the fibers being anchored by a pair of tubesheets, each tubesheet being adjacent to a head, the tubesheet and head being joined by a clamshell retainer. The cartridge does not have a core tube. The fibers are enclosed within a sleeve, the sleeve being sufficiently thin so as to be a non-structural element. The cartridge may be inserted within a larger pressure vessel. The cartridge of the present invention can accommodate more fibers than comparable cartridges of the prior art, and therefore has greater throughput.

Abstract: A hybrid nitrogen gas generation system includes a membrane nitrogen gas generator and a pressure swing absorption nitrogen generator. A gas comprising nitrogen is purified to a first nitrogen purity using one of the membrane nitrogen gas generator and the pressure swing absorption nitrogen generator. The gas is either bypassed around the other of the membrane nitrogen gas generator and the pressure swing absorption nitrogen generator to provide the gas having the first nitrogen purity or the gas is purified to a second nitrogen purity using the other of the membrane nitrogen gas generator and the pressure swing absorption nitrogen generator.

Abstract: A method of making a hollow fiber carbon molecular sieve (CMS) membrane includes heating a polymeric precursor to a pyrolysis temperature that is greater than or equal to 500 °C and less than or equal to 1200 °C; pyrolyzing the polymeric precursor at the pyrolysis temperature, thereby forming a pyrolyzed polymeric membrane; exposing the pyrolyzed polymeric membrane to an atmosphere comprising greater than or equal to 50 ppm oxidant; and cooling the pyrolyzed polymeric membrane to a cooling temperature that is less than or equal to 50 °C. The exposing and the cooling are performed sequentially or simultaneously, thereby forming the hollow fiber CMS membrane.

Abstract: An electroactive species includes a quinone core structure and at least one stabilizing group covalently bound thereto. The stabilizing group includes a cationic group, a hydrogen bond donor, or a combination thereof. The electroactive species has an oxidized state and at least one reduced state capable of bonding with a Lewis acid gas to form an anion adduct. Methods for separating a Lewis acid gas from a fluid mixture, electrochemical cells, and gas separation systems are also provided.

Abstract: Systems and methods to remove carbon from liquids such as seawater and other natural waters are described. The systems and methods utilize photoactive compounds to alter the pH of a fluid, drawing carbon out of the liquid and channeling it into a secondary environment. The carbon can be captured and sequestered or used in the formation of a product.
