  • Patent number: 9695049
    Abstract: An Ultra High Purity (UHP) carbon dioxide purification system and a method for purification of UHP carbon dioxide is disclosed. The purification system includes supported nickel oxide and supported palladium oxide. An upper portion of the purification system is at least partially filled with supported nickel oxide, and a lower portion of the purification system is at least partially filled with supported palladium oxide. The upper and lower portions of the purification system have a physical separation but are in fluid communication. The method includes purification or pre-purification of High Purity (HP) carbon dioxide to Ultra High Purity (UHP) levels including feeding carbon dioxide of High Purity grade or better to an Ultra High Purity carbon dioxide purification system.

  • Patent number: 9643845
    Abstract: A nitrous oxide room temperature purification method, apparatus and system utilizing at least partially oxidized nickel. In an embodiment, a room temperature regenerable N2O purifier includes a vessel having an inlet and outlet, an active portion being at least partially filled with a purification material comprising nickel oxide and optional elemental nickel, wherein the weight ratio between the nickel oxide and the optional elemental nickel is equal or higher than 3 and the surface area of the nickel oxide and the optional elemental nickel is equal or higher than 50 m2/g.

  • Patent number: 9211493
    Abstract: An apparatus for recycling exhaust gas includes a vessel containing a reversible ammonia sorber material which is exothermic when sorbing (“loading”) ammonia and which is endothermic when releasing (“unloading”) ammonia. A first valve selectively couples a source of exhaust gas including ammonia to a first port of the vessel, a second valve selectively couples a vacuum pump to the vessel, and a third valve selectively coupling a second port of the vessel to an output. A controller opens and closes the first valve, the second valve and the third valve to implement a loading phase, an intermediate venting phase and an unloading phase for the vessel.

  • Patent number: 8396547
    Abstract: A getter system (20) is provided for the sorption of organic molecules on the inside of active systems (30) for the transdermal release of drugs. The getter system is suitable to avoid the corrosion of electrical parts of these systems, caused by these organic molecules in the presence of water.

  • Patent number: 7918923
    Abstract: A fluid purifier includes an enclosure provided with an inlet and an outlet, and a plurality of different carbon based purifying media disposed within the enclosure which are capable of removing different contaminants. In a non-limiting embodiment, the purifier includes three carbon-based materials ordered according to a specific sequence. In an aspect of the non-limiting embodiment, the material closer to the purifier inlet may include acid-impregnated carbons, the centrally-located material may include base-impregnated carbons, and the material closer to the outlet may include activated carbons.
