  • Publication number: 20210301189
    Abstract: A method and apparatus for reclaiming refrigerant. The method includes transferring, an unreclaimed refrigerant composition, including one or more hydrofluoro olefins, from a source vessel to a receiving vessel and transporting the receiving vessel to a recycling center. The unreclaimed refrigerant composition is analyzed to determine the composition of the unreclaimed refrigerant composition sample. A target composition is determined, based on the analyzed unreclaimed refrigerant composition, and one or more treatments are determined, based on the target composition. The unreclaimed refrigerant composition is treated, with the one or more treatments, to form a reclaimed refrigerant composition having the composition of the reclaimed refrigerant composition is equal to the target composition.

  • Patent number: 5958273
    Abstract: An improved induction heated reactor apparatus involving a reaction zone with inlet and outlet and containing an array of electrically conductive catalyst entities (susceptor entities) comprising pellets, rings, or rods containing a core externally coated with a substantially uniform and complete catalyst metal (e.g., platinum, platinum-iridium alloy, or platinum-rhodium alloy) wrap, coating, or surface impregnated, or containing the catalyst metal as a foam which are inductively heated to produce chemical product from a catalytic reaction. Such an apparatus is particularly useful in the catalytic generation of HCN at elevated temperatures.

  • Patent number: 5900511
    Abstract: A process for continuous hydrogenation of adiponitrile (ADN) to hexamethylene diamine (HMD) and optionally to amninocapronitrile (ACN) involving the catalytic hydrogenation of adiponitrile at relatively low temperature (e.g., 75.degree. C.) and pressure (e.g., 500 psig) using a sponge cobalt catalyst (Raney.RTM. Co) in a reaction medium that is substantially free of caustic. In such a process periodic addition of water controls the production of side reaction products and the periodic addition of ammonium hydroxide rejuvenates the catalyst. Hexamethylene diamine is an important intermediate for the synthesis of polyamides such as Nylon-6,6 and aminocapronitrile is a potential intermediate of Nylon-6.
