Abstract
The packing has one or more thin-layer packing elements that are installed upright, the packing element having a main body portion with a planar liquid film formation surface, and one or more wall portions that are provided upright relative to the liquid film formation surface along a linear direction. The side surface of each wall portion has a curved portion at the base thereof connected to the liquid film formation surface, the curved portion curving so as to continue into the liquid film formation surface.
Claims10
A packing for gas-liquid contact, having at least one packing element of a thin layer shape that is placed in a standing position, the packing element of the thin layer shape comprising:
- a main body portion having a planar liquid film-forming surface extending along a liquid flow direction;
- and
- at least one wall portion that is provided upright relative to the liquid film-forming surface and extending along a liquid flow linear direction,
- wherein the wall portion has a side surface which has a curved surface portion at a base connected to the liquid film-forming surface, the curved surface portion curving so as to be continuous to the liquid film-forming surface, and
- wherein the curved surface portion is a concave surface along a cylindrical surface and is curved with a curvature radius at which a critical Weber number in a liquid film formed by a liquid on the liquid film-forming surface is minimized.
