ABSTRACT:
A method of recovering inert gas used during a filling process for pressurizing containers which are to be filled with a liquid. The method includes the steps of expelling the air found in the container, and pressurizing the container, with a mixture of air and heavy inert gas; filling the container with the liquid and thus expelling the pressurizing gas mixture; centrally collecting the expelled mixture from a plurality of containers and conveying the mixture to at least one accumulator; subjecting the pressurizing gas mixture in the at least one accumulator to at least one gravity effect for partially separating off the lighter gas components and producing a mixture of predominantly inert gas; adding additional inert gas to a mixture of predominantly inert gas; and returning the resulting mixture to the filling process, at least as a pressurizing gas mixture, for use with subsequent containers which are to be filled. Also provided is a device for carrying out this method for one or more counterpressure filling machines.
