An air separation module includes a canister having an inlet end and an outlet end arranged along a canister axis, a separator supported within the canister and arranged to separate a compressed air flow received at the air separation module into an oxygen-depleted air flow fraction and an oxygen-enriched air flow fraction, and an inlet cap. The inlet cap is seated about the inlet end of the canister, contains therein a portion of the separator, and has an oxygen-enriched air outlet port fluidly separated from the outlet end of the canister by the separator for diverting the oxygen-enriched air flow fraction to the external environment. Nitrogen generation systems and methods of making air separation modules are also described.

A system and device for drying and deodorizing coolers includes a core layer including a desiccant and a deodorizer encased within a liquid resistant vapor barrier material. The device also includes a first super absorbent layer including a super absorbent polymer encased within a liquid permeable fabric.

A spill-resistant and moisture absorbing device comprises a lid, a cover having a wall with an opening and attachably connected to the lid, a tray having an upper side and an underside and attachably connected to the cover from an upper side of the tray, and a basin having a cavity for collection of brine and attachably connected from the underside of the tray. The tray comprises a holder for holding a tablet.

A method of purifying a gas composed of a product gas and one or more impurity gases including combining a feed stream with a second stream thereby forming a combined feed stream, introducing the combined feed stream into a pressure swing adsorption device, thereby producing a high purity product gas stream and an off-gas stream, and introducing the off-gas stream into a membrane separation device, thereby producing a gas stream lean in product gas and a permeate stream.

A scent device comprises a container defining a volume and configured to hold a fill material, which may include one or more chemical compounds, natural formulations, or both configured to absorb odor and/or moisture, and/or emit a scent. The scent device includes a vented cap reversibly coupled to the container via a connection mechanism, and a breathable insert sandwiched between the container and the cap. The breathable insert may comprise a non-woven fabric supported along its perimeter by a structural mount. Methods of manufacturing the scent device involve cutting a mount from a support material, attaching a breathable material to the mount to form a breathable insert, depositing a scent-controlling material within a container, and sandwiching the breathable insert between the container and a cap upon coupling the cap with the container.

An adsorption storage tank for a natural gas includes a pressurizable tank disposed on a vehicle to contain the natural gas. A natural gas adsorbent is disposed in the tank. The natural gas is a mixture of constituents having a constituent statistical distribution of molecule lengths and kinetic diameters. The adsorbent has a pore size statistical distribution of pore sizes to adsorb and desorb the mixture of constituents.

Embodiments provide a methane microporous carbon adsorbent including a thermally-treated CVD carbon having a shape in the form of a negative replica of a crystalline zeolite has a BET specific surface area, a micropore volume, a micropore to mesopore volume ratio, a stored methane value and a methane delivered value and a sequential carbon synthesis method for forming the methane microporous carbon adsorbent. Introducing an organic precursor gas for a chemical vapor deposition (CVD) period to a crystalline zeolite that is maintained at a CVD temperature forms the carbon-zeolite composite. Introducing a non-reactive gas for a thermal treatment period to the carbon-zeolite composite maintained at a thermal treatment temperature forms the thermally-treated carbon-zeolite composite. Introducing an aqueous strong mineral acid mixture to the thermally-treated carbon-zeolite composite forms the methane microporous carbon adsorbent. The crystalline zeolite includes tri-ethanolamine (TEA) and has a shape that is orthogonal with a mid-edge length in a range of 8 m to 20 m.

A system and device for drying and deodorizing coolers includes a core layer including a desiccant and a deodorizer encased within a liquid resistant vapor barrier material. The device also includes a first super absorbent layer including a super absorbent polymer encased within a liquid permeable fabric.

A novel dehumidification frame includes a hemispherical cover body movably connected to the top of a supporting part, the supporting part, a base movably connected to the bottom of the supporting part, and a movable rod penetrating into the hemispherical cover body, the supporting part and the base. The hemispherical cover body, the supporting part and the base can rotate around the movable rod. The invention has the advantages of being simple in structure, convenient to use and attractive in appearance. The cover body, the supporting part and the base can be opened without being disassembled. A window is further arranged so that users can observe and timely remove water absorbed by a dehumidification bag to maintain cleanliness and sanitation.

Embodiments of the present disclosure describe methods of removing one or more compounds from a fluid comprising contacting a metal-organic framework (MOF) composition having a square-octahedral topology with a fluid containing one or more of CH.sub.4 and O.sub.2, sorbing one or more of CH.sub.4 and O.sub.2 with the MOF composition, and storing one or more of the CH.sub.4 and O.sub.2 with the MOF composition.
