  • PROCESS FOR CONVERSION OF WASTE FLUID STREAMS FROM CHEMICAL PROCESSING PLANTS TO BENEFICIARY AGRICULTURE PRODUCTS
    Publication number: 20110070144
    Abstract: The present invention is directed to the conversion of gas streams comprising ammonia, hydrogen sulfide, and water in the form of liquids or gases that are generated by petroleum refineries and coke ovens to beneficiary agriculture products, by forming ammonium sulfide and then converting the ammonium sulfide, using sulfuric acid, to pure ammonium sulfate.
    Type: Application

  • Process of making alkali metal tetrathiocarbonates
    Patent number: 6296828
    Abstract: Tetrathiocarbonate salt solutions are prepared by dissolving sulfur in carbon disulfide to form a sulfur solution. An alkali metal hydroxide solution is added to the sulfur solution, and an emulsion of the alkali metal hydroxide solution in the sulfur solution is formed. An alkali metal hydrosulfide is added to the emulsion to form the tetrathiocarbonate salt. The process yields tetrathiocarbonate salts in weight ratios up to about 9:1 with respect to trithiocarbonate salts. Aqueous solutions of tetrathiocarbonate salts can be produced in concentrations up to about 56 wt %, i.e., near saturation. The process also enables tetrathiocarbonate salts to be produced at or near atmospheric pressure and at only slightly elevated temperatures.

  • Process of making alkali metal tetrathiocarbonates
    Patent number: 6261529
    Abstract: Tetrathiocarbonate salt solutions are prepared by dissolving sulfur in carbon disulfide to form a sulfur solution. An alkali metal hydroxide solution and an alkali metal hydrosulfide are added to the sulfur solution to form the tetrathiocarbonate salt. The process yields tetrathiocarbonate salts in substantially higher weight ratios with respect to trithiocarbonate salts. Aqueous solutions of tetrathiocarbonate salts can be produced in substantially higher concentrations, even approaching saturation. The process also enables tetrathiocarbonate salts to be produced at or near atmospheric pressure and at only slightly elevated temperatures.
