Abstract
Abstract A mass exchanger with a cellular packing in form of checkerworks forming cells bent in the lower part forming the gaps. The bends of the cells are of radial or skew type. The checkerworks are formed by single or duplex walls. Alternate checkerworks are turned in relation to each other at about an angle of from 0° to 90°, an advantageous angle is 45°.

Claim 1
Independent Claim
143 words
A mass exchanger apparatus with a packing, said apparatus being defined by a chamber, inlet means connected to said chamber for directing fluid into said chamber interior; packing disposed in said chamber for contacting said fluid to act thereon; means for further treating said fluid; outlet means to direct said finally treated fluid outside of said chamber; and including a cellular packing the form of a checkerwork matrix defining perpendicular cells open at a top part thereof and having a bottom part provided with skew bends, said cells having gaps so formed at the bottom part by the skew bends permitting accumulation of liquid in said cells, said gaps are disposed to permit gas flow therethrough causing liquid in said cells to be foamed and excess liquid to be deflected by said bends and travel from said upper part to said bottom part.
