    摘要: The invention relates to a method for producing alcohols by homogeneously catalysed hydroformylation of olefins to aldehydes and subsequent hydration of the aldehydes. The invention further relates to a system for carrying out the method. The main focus is on the separation technique for work-up of the hydroformylation mixture. The problem addressed by the invention is that specifying a work-up method for hydroformylation mixtures that utilises the specific advantages of known separation technologies but at the same time largely avoids the specific disadvantages of said separation technologies. The most important objective is to create a catalyst separation system that is as complete and at the same time conservative as possible and that operates in a technically reliable manner and entails low investment and operating costs. The method should be unrestrictedly suitable for processing the reaction output from oxo systems in “world scale” format. The problem is solved by combining membrane separation units and a thermal separation unit, the thermal separation unit being operated in such a manner that 80% to 98% of the mass introduced with the product stream into the thermal separation unit exits the thermal separation unit again as a head product.

    摘要: The invention relates to a method for separating a homogeneous catalyst out of a reaction mixture by means of at least one membrane separation unit, in which method: the reaction mixture coming from a reaction zone and containing the homogeneous catalyst is applied as a feed to the membrane separation unit; the homogeneous catalyst is depleted in the permeate of the membrane separation unit and enriched in the retentate of the membrane separation unit; and the retentate of the membrane separation unit is recirculated into the reaction zone. The invention addresses the problem of specifying a method for separating homogeneous catalyst out of reaction mixtures that simplifies the feeding of fresh catalyst into the reaction zone and avoids disruptions to the hydrodynamics within the reaction zone when the volumetric flow of the reaction mixture output from the reaction zone varies. This problem is solved in that both the retentate volumetric flow of the membrane separation unit and the retention of the membrane separation unit are kept constant by regulation.
