Granted: 1991-11-26
Abstract: ABSTRACT      There is disclosed a method of electrolyzing an alkali metal chloride in brine in a membrane cell having at least an anolyte compartment and a catholyte compartment, which method comprises feeding the brine solution to the anolyte compartment, imposing a voltage across the cell thereby evolving chloride at the anode and an alkali metal hydroxide at the cathode, removing the salt-depleted brine solution from the anolyte compartment, separating the chlorine from the salt-depleted brine solution, resaturating the brine solution by contact with impure alkali metal chloride, treating the resaturated brine solution to remove impurities including alkaline earths and heavy metals, and recycling the brine solution as feed to the anolyte compartment, the improvement which comprises adding a controlled amount of a source of calcium ion to the salt-depleted brine solution, after the solution exits the anolyte compartment and prior to resaturation, followed by precipitation of calcium carbonate (CaCO3) from the brine solution by introducing an alkali metal carbonate after resaturation of the salt-depleted brine solution, whereby the sulfate concentration entering the membrane cell is controlled.  As disclosed, this method is useful in controlling sulfate concentration by preventing dissolution of sulfate impurities found in the salt.

Abstract: Case 71 CIP of Case 63 OMNIAXIS APPARATUS FOR PROCESSING PARTICULATES AND THE LIKE                Abstract An apparatus for processing praticulates comprises a vibratory bed including a motor with a vertically disposed shaft,  separate  remotely  adjustable  vibratory  generating apparatus mounted on each end portion of the shaft and at least three contact structures between the vibratory bed and a  flask  or  vessel  containing  the  particulates.   The uppermost vibratory generating apparatus being remotely ad-justable to vary the horizontal vibratory force component and the lowermost vibratory generating apparatus being re-motely adjustable to vary the vertical conical force compo-nent.  The contact structures have conically shaped mating surfaces on pins and in recesses in sockets such that when at least one of the conically shaped surfaces are in contact the vessel is restrained to the same horizontal movement as the bed plate.  When vibrational gyratory motion of the bed plate has an acceleration in excess of gravity,  the bed plate will impact the vessel with A vertical component pro-gressively from one contact structure to the next at multi-ple frequencies for each revolution of the shaft.  The im-pacts at the multiple frequencies will fluidize the particu-lates so that the particulates will flow into cavities and crevices in a pattern or the like in the vessel.
