Abstract: A method for at least partially draining an operating system, which contains a working fluid including carbon dioxide (R744) and a halogenated hydrocarbon. The method includes transferring the working fluid to a target container, from the operating system, wherein the working fluid is contacted with an absorptive bed. The working fluid may include between 10% and 35% by weight of halogenated hydrocarbon. The method may include an absorptive bed treatment step prior to the contacting step.
