Abstract: A refrigeration system including a flooded evaporator. The flooded evaporator additionally includes a liquid evaporator refrigerant composition and a vapor evaporator refrigerant composition. The liquid refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf) and the vapor refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf). The mass fraction of difluoromethane in the liquid evaporator refrigerant composition is lower than the mass fraction of difluoromethane in the vapor evaporator refrigerant composition and the mass fraction of 2,3,3,3-tetrafluoropropene in the liquid evaporator refrigerant composition is greater than the mass fraction of 2,3,3,3-tetrafluoropropene in the vapor evaporator refrigerant composition.

Abstract: In an embodiment, a method of producing a fluoroolefin comprises coupling 3,3-dichloro-1,1,1,2,2-pentafluoropropane (CF3—CF2—CHCl2) in a liquid phase in the presence of a catalyst to form a composition comprising 1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CH═CHCF2CF3). In another embodiment, a method of producing a fluoroolefin comprises coupling 1,1,1-trichloropentafluoropropane (CF3—CF2—CCl3) in a vapor phase in the presence of a first catalyst to form a composition comprising 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3—CF2—CCl═CCl—CF2—CF3). The method may further include forming the CF3—CF2—CCl3 in a vapor phase from CF3CF2CHmCl3-m and chlorine (Cl2). The method may further include hydrodechlorinating the 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene with hydrogen (H2) in a vapor phase in the presence of a second catalyst to form a composition comprising CF3CF2CH═CHCF2CF3 and 3-chloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CCl═CHCF2CF3).

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.
