This distillation column comprises a cross-corrugated packing module formed from strips having corrugations that define channels ( 14 ), each channel lying between two main peaks ( 12; 10 ) and each channel having two channel legs ( 16 ) that are joined together by a top main peak ( 10; 12 ). The strip ( 2 ) comprises an inverted portion ( 22 ) which lies within the cross section of one of the channels ( 14 ) and which includes a first intermediate peak ( 26 ) oriented in the opposite direction to the top main peak ( 10; 12 ). The inverted portion ( 22 ) includes a second intermediate peak ( 28; 30 ) oriented in the direction of the top main peak ( 10; 12 ). Application to air distillation installations. |
