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.
