Abstract: This invention relates to an evaporative salt plant installation including methods of operation and apparatus which produce high purity salt economically and in high yield comprising the combination of a gas turbine which drives a vapor compressor, whose exhaust gases are used to produce steam to drive a topping steam turbine generator, which in turn generates the electrical energy requirements of the plant, and wherein the discharge vapors from the steam turbine are combined with the discharge vapors from the vapor compressor, which is in turn in combination with a vapor compression evaporator and a purge evaporator, whereby both evaporators produce salt, and where the overhead vapors of the purge evaporator are used in a brine cooled condenser to preheat input cold brine, thereby producing water condensate which is recovered, along with evaporator steam chest condensate streams, and used in solution mining underground salt, thereby allowing for both the productive use and recovery of substantially all the r

Abstract: Improved electrolytic cell performance is obtained by modifying a standard box anode by increasing the width thereof by permanently deforming the anode mesh within the immediate vicinity of the anode post. Increases in anode width of from about 3 mm to about 12 mm, resulting in reduction of interelectrode gap of about 1.5 mm to about 6 mm, have been found advantageous. Improvement is enhanced by the use of a polymer bonded asbestos diaphragm.

Abstract: A particulate deodorizing poultry litter is described. The litter is a mixture comprised of from about 80 to about 95 percent by weight ferrous sulfate heptahydrate; from about 0.1 to about 3.5 percent by weight iron oxide and may contain from about 0.2 to about 1.5 percent calcium carbonate. The particles have from about 0.1 to about 0.5 percent by weight free sulfuric acid distributed on their surfaces. The particles range in size from about 0.02 to about 0.2 inches in diameter. The ammonia produced by zymosis of bird drippings is effectively reduced and maintained at levels less than 50 parts per million and usually less than 30 parts per million.
