PROBLEM TO BE SOLVED: To provide a regular filling material which does not cause such a problem that mass transfer performance is deteriorated even when the regular filling material is applied to a packed column having a small diameter, and to provide a gas-liquid contact apparatus in which the regular filling material is used.SOLUTION: The regular filling material is inserted into and packed in the cylindrical packed column having the inside diameter smaller than 100 mm and is obtained by stacking a plurality of sheet materials 5, each of which comprises a thin metal sheet. The sheet materials 5 are constituted of three kinds of sheet materials being a first sheet material 5a both side surfaces of which are formed to be perpendicular to the sheet surface, a second sheet material 5b both side surfaces of which are formed to be inclined to the sheet surface at 37° to 43°, and a third sheet material 5c both side surfaces of which are formed to be inclined to the sheet surface at 67° to 73°. Each of three kinds of sheet materials 5 has 4 mm or longer bend height. A width of the first sheet material 5a to that of the third sheet material 5c become gradually narrower in this order. The first sheet material 5a to the third sheet material 5c is disposed in this order from the central part of a stacked body toward the outside of the stacked body.SELECTED DRAWING: Figure 1 |
