A method for separating a gas mixture at subambient temperature, in which a gas mixture is sent to a heat-insulated chamber, cooled and separated in a column, and placed inside the chamber so as to produce at least two fluids, each of which is enriched with a component from the gas mixture. At least one fluid from the method can be heated inside the chamber or vaporized via heat exchange with at least one heating member including at least one element having magnetocaloric properties and built into a circuit configured to conduct a magnetic flux. The element is alternatingly in thermal contact with a cold source, made up of the fluid to be heated, and a hot source, made up of a source hotter than the fluid to be heated, and variation in the magnetic flux via the magnetocaloric effect generates electrical and/or mechanical energy. |
