ABSTRACT:
A packing material capable of improving the uniformity of liquid distribution and of achieving a preferable gas-liquid contact reaction, even in the case where the specific surface area of the packing material is small, includes a plurality of projections provided on the surface of a thin plate, and a plurality of holes provided respectively between the projections. In one embodiment, the transfer extension of each projection is larger than a longitudinal extension thereof, so that descending liquid flows downward while being transversely dispersed by the projection. The holes are provided between the projections so that they do not obstruct the transfer dispersion of liquid at the projection. Moreover, the holes accelerate the transverse dispersion of liquid, or the dispersion of liquid between front and rear surfaces of the thin plate, by the surface tension of the liquid. As a result, excellent uniformity of liquid distribution can be obtained on the surface of the thin plate. An improved air separator containing the packing material incorporated into a rectifier for performing gas-liquid contact reaction is also disclosed.
