<p>PURPOSE: To provide a packing material which improves dispersion property of a liquid on a thin plate made of the packing material, improves the efficiency for gas liquid contact and realizes a good rectifying efficiency, and to improve performance of a packed tower by using a rectifying column for gas-liquid contact equipped with this packing material. CONSTITUTION: The surface of a thin plate 1 is provided with lots of projected parts 2 with specified distance in the horizontal direction which represents the i-th line and with a continuous projected part 3 as the (i+1)-th line in the horizontal direction. These lines are stacked in the axial direction of the tower. The liquid 4 flowing downward is dispersed to a short distance by the projected parts 2 in the i-th line and flows downward to the projected part 3 in the (i+1)-th line. Since the projection 3 is continuous in the horizontal direction, the dispersion distance in the projection 3 is long. By the repetition of the short distance and long distance of dispersion, a good distribution state of the liquid is obtd. on the surface of the thin plate 1.</p> |
