Abstract: Mass transfer sorption processes involve passage of a processed aqueous solution through a layer of granulated sorbent pre-filled with an organic liquid immiscible with either water or an aqueous solution under treatment. The apparatus for mass transfer of sorption processes is a vertical tank with inlet and outlet fittings loaded with a layer of sorbent disposed between the upper and the lower distribution and drainage systems. The industrial plant for separation of the components of aqueous solutions of inorganic substances includes the said apparatus and the apparatus for the separation of organic liquids from aqueous solutions. The latter has a casing with three chambers, the middle one of which is separated from the first outer one by a grid and from the other by a hydrophobic drainage layer. The emulsion to be separated is introduced into the middle chamber, and the separation results are derived from the outer chambers.
