Abstract
A packing for gas-liquid contact has at least one packing element of a thin layer shape, placed in a standing position. The packing element has a main body portion having a planar liquid film-forming surface extending along a liquid flow direction, and at least one wall portion provided to stand relative to the liquid film-forming surface and extending along the liquid flow direction. The wall portion has a side surface inclined at a predetermined angle to the liquid film-forming surface in a surface position of a liquid film to be formed by a liquid on the liquid film-forming surface.

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
- a wall portion that is provided to stand relative to the liquid film-forming surface and extending along the liquid flow direction,
- wherein the wall portion has a side surface which has an inclined surface inclined at a predetermined angle to the liquid film-forming surface in a surface position of a liquid film to be formed by a liquid on the liquid film-forming surface, and
- wherein the predetermined angle is an angle in a range including a receding contact angle to be formed by the liquid to the side surface.
A method for manufacturing a packing having at least one packing element of a thin layer shape that is to be used by placing in a standing position, comprising:
- a designing step of designing a packing element of the thin layer shape comprising:
- a main body portion having a planar liquid film-forming surface;
- and a wall portion that is provided to stand relative to the liquid film-forming surface along a straight line, wherein the wall portion is designed to have a side surface which has an inclined surface inclined at a predetermined angle to the liquid film-forming surface in a surface position of a liquid film to be formed by a liquid on the liquid film-forming surface, and the predetermined angle is an angle in a range including a receding contact angle to be formed by the liquid to the side surface;
- and
- a fabricating step of fabricating the designed packing element of the thin layer shape, using a raw material.
A liquid film-forming structure for forming a liquid film by a liquid to be supplied, comprising:
- a main body portion having a planar liquid film-forming surface;
- and
- a wall portion that is provided to stand relative to the liquid film-forming surface,
- wherein the wall portion has a side surface which has an inclined surface inclined at a predetermined angle to the liquid film-forming surface in a surface position of the liquid film to be formed by the liquid on the liquid film-forming surface, and
- wherein the predetermined angle is an angle in a range including a receding contact angle to be formed by the liquid to the side surface.
