The invention relates to a cryogenic process for obtaining a product of value, in particular hydrogen, from a hydrogen-rich input gas, in particular a hydrogen-rich natural gas, comprising the following steps: in a first separation column (T1) hydrocarbons having two or more carbon atoms are separated, in a second separation column (T2) methane is separated off, and in a third separation column (T3) nitrogen is separated off, wherein the hydrogen-rich input gas after optional prepurification R is supplied to the separation columns T1 to T3 according to steps a) to c) and the separation columns effect separation into a liquid fraction, the bottoms product, and a gas fraction, the tops product. In the cryogenic process according to the invention, provision of refrigeration is preferably effected at least partially via one or more refrigeration circuits.
