Abstract
The invention relates to a device for supplying a purified gas to a plant which is purged with purified gas. The device includes a feed line connected, on the one hand, to a source of substantially pure gas and, on the other hand, to an inlet of the plant. The purified gas being passed therethrough is contaminated with impurities. The device further includes a line which is intended to recover the contaminated gas at the outlet of the plant and is connected to the feed line. The lines are arranged one after the other downstream of where the recovery line is connected to the feed line, a compressor and a device for separating the impurities from the contaminated gas by permeation in order to supply a purified gas to the plant.
