MEMBRANE CASCADE WITH FALLING SEPARATING TEMPERATURE |
摘要 |
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. This problem is solved by the use of a membrane cascade with falling separation temperature. |
