Abstract
This process serves for separating a gas mixture (4), in particular air, a product (21; 23), in particular nitrogen, enriched with lower-boiling components, being obtained. A lower-boiling fraction (18, 19) from the upper region of a rectifier column (7) is at least partially condensed in a condenser/evaporator (11) in indirect heat exchange with an evaporating higher-boiling fraction (8). The higher-boiling fraction (8) is, before the indirect heat exchange, supplied with a further fraction (24) which has a lower proportion of higher-boiling components than the higher-boiling fraction (8). <IMAGE>
