PROCESS AND APPARATUS FOR LIQUID-SOLID CONTACTING

摘要

In a continuous liquid-solid contacting process with intermittent counter-current movement of particles between horizontally adjacent vessels, particle movement is effected by flowing liquid upwardly from a lower region of one vessel through a particle collection conduit into a lower region of an adjacent vessel. The sides of the vessel converge downwardly adjacent the inlet end of the conduit to a collection zone from which the particles can be transferred efficiently. A novel form of vessel for use in apparatus for carrying out the process is also disclosed.
