Patent number: 7147215Abstract: A corrugated strip made of sheet material, which may be used in a packing module. The peaks and the troughs of the strip, when viewed in a side view, define lines which have a general sloping direction relative to the direction the fluid flow. Each strip includes a spanning zone and a transition zone. In the transition zone, each peak/trough line extends inside a specific area centered on a curve which extends tangentially from the peak/trough line of the spanning zone. The structured interface region between the spanning and transition zones helps to reduce head loss across the strip.Type: GrantFiled: December 6, 2002Date of Patent: December 12, 2006Assignee: L'Air Liquide, Societe Anonyme a Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges Georges ClaudeInventors: Jean-Yves Lehman, Etienne Werlen, Gilles Lebain

Publication number: 20050040549Abstract: The invention concerns a corrugated packing module for treating a fluid delimited by two channels (18). It comprises a running zone (4) whereof the channels define ridge lines (26) having a global sloping direction (D1) relative to a general direction of circulation (Df) of the fluid. The strip comprises a transition zone (6, 8) adjacent to the running zone (4). Each ridge line (26) of the transition zone (6, 8) extends inside a specific zone centered on a curve (A) which extends tangentially the ridge line (26) of the running zone (4). The radial width (Lr) is 10% of the corresponding radius of curvature of the curve (A). The radius of curvature (Rc) of the curve (A) is at all points 1.5 times greater than the hydraulic diameter (Dh) of a channel (18). The invention is applicable to air distillation columns.Type: ApplicationFiled: December 6, 2002Publication date: February 24, 2005Inventors: Jean-Yves Lehman, Etienne Werlen, Gilles Lebain
