Abstract (en)
[origin: WO2015166191A1] The invention relates to a method for cooling, purifying and separating a gaseous mixture (1) containing at least one impurity, in which the gaseous mixture is cooled to a temperature no higher than the temperature at which the at least one impurity solidifies in a heat exchanger (3, 3A) having cooling passages, the cooling passages being at least partially covered with a coating and/or physically treated and/or chemically treated, the coating and/or the treatment serving to limit or even to prevent the solidified impurity from forming and/or adhering to a surface of the passages; at least one portion (5B, 19) of the solidified impurity exiting the cooling passages of the heat exchanger is collected; and the gaseous mixture is drawn from the heat exchanger.
