Abstract

A method and a device for separating argon from a gas mixture. The method includes steps of collecting the gas mixture, separating the oxygen present in the gas mixture, drying the gas mixture, and cryogenically purifying the remaining gas mixture for separating the argon in liquid form. The device for performing the method includes a collector for the gas mixture, a component for catalytic and/or adsorptive separation of oxygen from the gas mixture, a component for drying the gas mixture, and a system for cryogenically purifying the gas mixture and separating the argon in liquid form.
