In a method for separation at sub-ambient temperature, a mixture of fluid at sub-ambient temperature is sent to a system of separation columns comprising at least one separation column, a fluid enriched in a lighter component of the mixture leaves the top of one column of the system and a fluid enriched in a heavier component is withdrawn from the bottom of one column of the system, the cold source of a heat pump using the magnetocaloric effect is thermally connected to a first zone of one column of the system and the hot source of the same heat pump is thermally connected to a second zone of the same or of another column of the system.

A method for separation at sub-ambient temperature, the method comprising the steps of:
A device for separation at sub-ambient temperature, comprising a system of separation columns comprising at least one separation column to which a mixture of fluid at sub-ambient temperature is sent, a pipe for withdrawing a fluid enriched with a lighter component of the mixture from the top of one column of the system and a pipe for withdrawing a fluid enriched in a heavier component from the bottom of one column of the system, in which the cold source of a heat pump using the magnetocaloric effect is directly or indirectly thermally connected to a first zone of a column of the system and the hot source of the same heat pump being directly or indirectly thermally connected to a second zone of the same or of another column of the system, the arrangement of the first and second zones in the column or columns being such that the minimum temperature of the first zone is lower than the maximum temperature of the second zone.
