Abstract: An apparatus for pumping and mixing plural components of differing viscosities having at least one hopper for accepting each component, each hopper having a hopper outlet; an auger secured within each hopper, the auger being designed to wipe the inside surface of its respective hopper during rotation; a piston pump plumbed to each hopper outlet, each piston pump being substantially identical and having a pump inlet and a pump outlet, and each piston pump designed to be joined by a coupling yoke, whereby components of differing viscosities can be pumped uniformly; and a static mixer. The static mixer has a mixer inlet and a mixer outlet, and is designed so that plural components of differing viscosities can be uniformly pumped and mixed.

Abstract: In a process for chlorinating titanium containing material in a fluidized bed reactor which evolves gaseous material including CO, COS, and TiCl.sub.4, the improvement comprising introducing oxygen containing gas at a location or locations which are downstream of the surface of the bed, as measured in its static condition, to convert at least some CO to CO.sub.2 and some COS to CO.sub.2 and SO.sub.2.

Abstract: A process for reducing the amount of carbon monoxide emitted from a fluidized bed reactor for chlorinating titanium bearing material containing iron oxide comprising (a) feeding coke, titanium bearing material containing iron oxide, and chlorine to the reactor, the chlorine being fed to the reactor below the surface of the fluidized bed, (b) maintaining the feed rate of the materials in step (a) and the conditions of operation of the bed so that the iron oxide is substantially converted to ferrous chloride, and (c) feeding sufficient chlorine to the reactor at or near the surface of the bed to convert the desired amount of carbon monoxide to carbon dioxide.
