Abstract

The invention relates to a method and a process plant for enrichment of a component, which uses a first membrane stage (1) and a pressure swing adsorption stage (2), wherein the first membrane stage (1) is fed with a first feed mixture (F1) containing the component and the pressure swing adsorption stage (2) is fed with a second feed mixture (F2) containing the component. In the first membrane stage (1) a first permeate (P1) and a first retentate (R1) are formed and in the pressure swing adsorption stage (3) a product (PR) and a recycling product (RE) are formed. The second feed mixture (F2) is formed at least partially from the first permeate (P1). The first permeate (P1) is continuously analysed by a detector (4) to determine the concentration of the component in the first permeate (P1) and, if the concentration of the component in the first permeate (P1) is below a first predetermined threshold value, a first control valve (CV1) is opened so that part of the first permeate (P1) is routed upstream of the first membrane stage (1) and the first feed mixture (F1) is formed at least partially by the first permeate (P1), and, if the concentration of the component in the first permeate (P1) is above a second predetermined threshold value, a second control valve (CV2) is opened to deplete part of the second permeate.
