  • Membrane cascade with falling separation temperature
    Patent number: 9713791
    Abstract: The invention relates to a process for separating a composition of matter with the aid of a membrane cascade having at least two stages, in which a separation is effected in each stage at at least one membrane at a separation temperature set for the particular stage. The invention further relates to a corresponding membrane cascade, to the use of said membrane cascade for catalyst separation from homogeneously catalyzed mixtures, and to a process for hydroformylation, in which the catalyst is separated by means of a membrane cascade. The problem addressed thereby is that of specifying a membrane-based process for separating compositions of matter, which has a minimum membrane area requirement and nevertheless fulfills the separation task and separation performance required. This problem is solved by the use of a membrane cascade with falling separation temperature.

  • MEMBRANE CASCADE WITH FALLING SEPARATION TEMPERATURE
    Publication number: 20160158703
    Abstract: The invention relates to a process for separating a composition of matter with the aid of a membrane cascade having at least two stages, in which a separation is effected in each stage at at least one membrane at a separation temperature set for the particular stage. The invention further relates to a corresponding membrane cascade, to the use of said membrane cascade for catalyst separation from homogeneously catalysed mixtures, and to a process for hydroformylation, in which the catalyst is separated by means of a membrane cascade. The problem addressed thereby is that of specifying a membrane-based process for separating compositions of matter, which has a minimum membrane area requirement and nevertheless fulfils the separation task and separation performance required.
