Abstract
A packing structure obtained by assembling packing elements having a spiral helix shape, and the use of a structured packing composed of packing structure for an operation for bringing a gas into contact with a catalyst, and a process for manufacturing such a structured packing.
Claims9
A packing structure (20) comprising at least two juxtaposed series of identical packing elements (21), in which
- said packing elements (21) are twisted plates having a spiral helix shape,
- a series comprises at least two packing elements (21) adjoining in the direction of their heights,
- the packing elements (21) of two separate series are juxtaposed in a substantially parallel fashion and in the direction of their heights, the edges (22, 23) of the two ends of the packing elements (21) of one and the same series are substantially parallel to each other, and the packing structure comprises at least two series in which the edges (22, 23) of the ends of the packing elements (21) of two juxtaposed series are substantially perpendicular, and the edges of four adjacent packing elements of two juxtaposed series form a square the edges of which are constituted by the edges of said four elements.
