Definitions
- the method according to the invention may have one or more of the following characteristics:
- the cooled gas stream 3 is sent to the adsorption unit 4 where at least one impurity X is at least partially adsorbed so as to recover a gaseous stream 5 depleted in impurity X; c) the gas stream depleted in impurity X 5 is introduced into the exchanger 2 to be cooled to a temperature below -50 ° C, preferably -150 ° C;
- the feed gas stream comprises water and said process comprises, before step a), a step of pre-purification of the feed gas stream making it possible to remove at least a portion of the water;
