Abstract
The present invention provides for a structured packing element, the element being corrugated with corrugations which form alternating peaks and troughs across the element, the corrugations having a longitudinal axis, the element having at least one band of first fluting at an angle between 0.degree. and 180.degree. to the longitudinal axis of the corrugations and at least one band of second fluting at an angle between 0.degree. and 180.degree. to the longitudinal axis of the corrugations, the first fluting being at an angle greater than zero to the second fluting. The element preferably has a plurality of holes through the element. The foregoing structured packing is suited for use in processes requiring a contact device for accomplishing mass and/or heat transfer. The foregoing structured packing is particularly suited for a cryogenic air separation process comprising contacting vapor and liquid countercurrently in at least one distillation column containing at least one mass transfer zone wherein liquid-vapor contact is established by at least one structured packing element.
