A packed mass transfer tower for establishing intimate gas-liquid contact and efficient mass transfer that is less susceptible to gas or liquid channeling, gas surging and uneven distribution of gas or liquid across the cross-sectional area of the tower. In one embodiment, the packed tower includes a packing arrangement including a loosely packed bed of mobile packing material, and an adjacent, tightly packed bed of mobile packing material. The relatively tightly packed bed of mobile packing material acts as a gas distributor, as well as being a material that causes good gas-liquid contact, to provide an even flow of gas across essentially the entire cross-sectional area of the loosely packed bed of mobile packing material. In another embodiment, mobile packing elements and fixed packing elements are intermixed between the same spaced fluid-pervious grids. In the second embodiment, the fixed packing elements hug the lower pervious grid to evenly distribute gas and liquid to the mobile packing elements that are aerated above the fixed packing elements during mass transfer.

A packed tower for use in gas-liquid contacting forming solid particulates within the tower, comprising; at least one loosely packed bed of mobile parking elements disposed in said tower; at least one packed bed of relatively fixed mobile packing elements disposed in said tower vertically adjacent to said loosely packed bed; said mobile packing elements in both the loosely packed bed and the relatively fixed packed bed having a density such that the packing elements float in water; means for flowing gas sequentially through said packed beds; and means for flowing liquid essentially through said packed beds for intimate contact and mass transfer with said gas.
