Rtl Contactor Holding S.a.

Theodor J Hohlbaum

Apparatus for contacting immiscible or partly miscible liquids, for example in an extraction process in the form of a container through which the liquids flow having a plurality of discs arranged to rotate and dividing the container into connected compartments, a ring of foraminous material, capable of receiving and temporarily storing liquid, being arranged between at least one pair of discs, so that, in use, liquid is carried from one phase and shed in the other phase.

Apparatus for contacting liquids

A solids/liquid contactor comprises a drum through which a slurry phase and a treatment liquid phase pass, a rotor within the drum including a plurality of axially-spaced discs dividing the drum interior into a series of compartments, the edges of the discs being spaced from the wall of the drum to form an annular passage for the movement of the phases from compartment to compartment, for each of at least some of the compartments, a plurality of receptacles mounted to rotate with the rotor and designed to receive material of one phase and to shower it into the other phase as the rotor turns, and at least one blade which is carried by the rotor, which penetrates into the annular passage, and which is operable to maintain the passage at least partly clear of stationary solids.

Apparatus for and methods of contacting materials

A continuous liquid/liquid or liquid/solids contactor consists of a rotary contactor having a near horizontal axis. The interior of the drum is divided axially into a number of compartments by spaced discs secured to the drum wall and having openings through which the materials to be contacted can pass from one end to the other of the drum. In each compartment, there are a number of buckets which are carried by the discs and which in operation serve to cause intermingling of the materials to be contacted. At the ends of the drum are inlet and outlet passing through rotary joints in the drum ends and carrying the streams to be brought into contact.
