  • Wet oxidation process and system
    Publication number: 20050171390
    Abstract: A process and system for the destruction of compounds having a carbon-hetero atom bond. The process includes wet oxidation at elevated temperature and pressure of an aqueous mixture of at least one compound having a carbon-hetero atom bond to substantially destroy the carbon-hetero atom bond of the at least one compound. The resulting oxidized material may be further treated in an advanced oxidation process to destroy any residual carbon-hetero atom bonds remaining.

  • System and method of wet oxidation of a viscose process stream
    Publication number: 20050147554
    Abstract: A wet oxidation process is used to control the concentration of reduced sulfur compounds from a viscose process. The wet oxidation process oxidizes the reduced sulfur compounds to convert such reduced sulfur compounds to an alkali sulfate and/or thiosulfate species. The alkali sulfate stream is recycled to the viscose process. Oxidation is performed under elevated temperature and pressure conditions such that the offgas has an oxygen concentration of between about 2% to 18% and the alkali sulfate stream has a pH of about 2 to 10.
