Process for the gas treatment of a product in a confined treatment zone by a flow of an inert gas, such as nitrogen, wherein a gas flow which originates from a gas treatment containing a high proportion of nitrogen, becomes loaded with impurities such as: oxygen, and/or carbon dioxide, and/or water, and wherein the flow of gas which originates from the treatment undergoes at least substantially in part, a removal of the impurities in a separator of the adsorption or permeation type before being recycled as treatment gas, with addition of a compensating gas flow predominantly containing nitrogen. Application for example to the deoxygenation of liquids, in particular nutritious liquids, to the providing of inert conditions in ovens or storage enclosures for products such as electronic pieces, or in chambers used for preserving nutritious products in an atmosphere which is substantially free from oxygen. |
