Abstract: The present invention relates a process for separating H2, preferably both H2 and CH4, from a gas mixture comprising H2 and CH4 by means of a series of selective membrane units that avoids compressors and vacuums as well as an apparatus for carrying out said separation.

Abstract: The present invention relates to a method for concentrating aqueous solutions of human milk oligosaccharides, in which an aqueous solution comprising at least one human milk oligosaccharide is subjected to a reverse osmosis process by means of a reverse osmosis membrane and is thereby concentrated to a final osmotic pressure of at least 70 bar measured with a freezing point osmometer. Moreover, the present invention refers to an according use of a reverse osmosis membrane, a corresponding reverse osmosis system containing such a membrane and a spray-dried HMO product obtainable by the method.

Abstract: A first aspect of the invention relates to a process for separating 1-methoxypropan-2-ol from an aqueous stream comprising 1-methoxypropan-2-ol and 2-methoxypropan-1-ol, wherein the process comprises providing a stream SO comprising 1-methoxypropan-2-ol, 2-methoxypropan-1-ol and water, and having a molar ratio of 1-methoxypropan-2-ol:2-methoxypropan-1-ol in the range of from 1:5 to 5:1; wherein the final stream S5 comprises ?95 weight-% 1-methoxypropan-2-ol based on the total weight of S5. In a second aspect, the invention relates to 1-methoxypropan-2-ol or a mixture of 1-methoxypropan-2-ol and 2-methoxypropan-1-ol obtained or obtainable from the process of the first aspect.

Abstract: The present invention relates to a process for separating 1-methoxypropan-2-ol in a stream S3 from an aqueous stream comprising 1-methoxypropan-2-ol and 2-methoxypropan-1-ol, wherein the process comprises providing a stream S0 comprising 1-methoxypropan-2-ol, 2-methoxypro-pan-1-ol and water, and having a molar ratio of 1-methoxypropan-2-ol:2-methoxypropan-1-ol in the range of from 1:5 to 5:1. A further aspect of the invention also relates to 1-methoxypropan-2-ol obtained or obtainable from said process, as well as to a mixture of 1-methoxypropan-2-ol and 2-methoxypropan-1-ol, preferably obtained or obtainable from said process, which preferably comprises in the range of from 95 to 100 weight-% 1-methoxypropan-2-ol and ?0.5 weight-% of 2-methoxypropan-1-ol, each based on the total weight of the mixture.

Abstract: The present invention relates to a method for improved demineralization of fermentation broths, including the steps of providing a solution comprising one or more oligosaccharides, carrying out a first membrane filtration and preferably being a microfiltration or ultrafiltration, a second membrane filtration of the permeate of the first membrane filtration and a first nanofiltration step; with a sub-step of concentration and/or a sub-step of diafiltration. Moreover, the present invention is directed to an improved purification of fine chemicals from a fermentation broth.

Abstract: The present invention relates to a method for separating biomass from a solution comprising bi-omass and at least one aroma compound. comprising providing the solution comprising bio-mass and aroma compounds. lowering the pH value of the solution below 7 by adding at least one acid to the solution comprising biomass and the at least one aroma compound. adding an adsorbing agent to the solution comprising biomass and aroma compounds. and carrying out first membrane filtration so as to separate the biomass from the solution comprising the at least one aroma compound.
