ABSTRACT:
Rotary processors and methods for purifying a viscous liquid material by liquid-liquid extraction. Material is introduced to an extracting apparatus including a mixing rotary processor comprising at least one annular channel carried by a rotor and enclosed by a housing to form a mixing passage. The material is dragged forward by the rotating channel from the passage inlet past a blocking member. Solvent introduced to the passage, such as by spray means, is carried downstream with the material and dispersed in material collected at a passage end wall. In one embodiment the blocking member comprises a spreader which spreads the material as films on the channel walls. In another embodiment, sparging means sparges solvent into a pool of the material collected upstream of the blocking member. Separation of the solvent from the material may involve rotary devolatilizing or phase separating processors, which may be arranged with the mixing processor for cocurrent or countercurrent, multi-stage series operation.
