Abstract
A process for continuous flush of a pigment press cake involves applying a dispersant to the press cake to produce a fluidized press cake, continuously feeding the fluidized press cake into a twin screw extruder and mixing it with a neutralizing agent in the extruder, mixing the neutralized press cake with a liquid organic medium in the extruder to produce an organic flush phase and a water phase, and removing at least part of the water phase from the extruder through one or more parts of the extruder.
