Abstract
A process for producing a purified gas stream having impurities, using a production unit for producing a gas stream and a storage reservoir. The process includes producing a first gas stream by means of the production unit. Storing at least a portion of the first gas stream in the storage reservoir. Extracting, from the storage reservoir, a second gas stream corresponding to at least one portion of the first stream polluted by the impurities. Purifying the second gas stream by transfer of at least one portion of the impurities contained in the second gas stream into the first gas stream. And recovery of the purified gas stream at the output of the purification.
