Method and installation of the gaseous treatment of a product in a treatment zone confined, application for the deoxygenation of liquid food

摘要

Process for the treatment of gaseous product in a confined treatment zone 1 - 2 by a gas stream 5 - 11 essentially consisting of the inert gas, such as nitrogen, in which a stream of gas coming from the treatment of 20 to high nitrogen content is enriched with impurities such as oxygen, and / or carbon dioxide gas, and / or water, in which the gas stream coming from the treatment of 20 is subjected, at least a substantial part, a purification of the impurities in a separator of the adsorption or permeation 22 before being recycled 5, 4, as the treatment gas, with the addition 11 - 25 - 26 - 27 of a gas flow rate of compensation predominantly containing nitrogen. / p & & p & application in particular for the deoxygenation of liquids, in particular comestible liquids, the inerting of furnaces or to the chambers of the storage of products such as the electronic parts, or to the chambers of the storage of food products in an atmosphere which is substantially free of oxygen.
