Siemens Water Solutions Launches Zimpro Electro-Oxidation Technology for Spent Caustic Treatment
Sep 19 16
Siemens Water Solutions has launched Zimpro Electro-oxidation technology for Spent Caustic Treatment. Designed to address needs of refinery and petrochemical industries, Zimpro® Electro-oxidation System uses electrically conductive boron doped diamond electrodes, enabling efficient oxidation of organic and inorganic compounds that are dissolved in spent caustic. System's flexible, modular design is capable of treating highly contaminated spent caustic streams. Treatment using Zimpro electro-oxidation produces effluent that is amenable to traditional wastewater treatment processes. Process addresses needs of refinery and petrochemical spent caustic treatment. Flexible, modular design capable of treating highly-contaminated streams. Uses electrically conductive boron doped diamond (BDD) electrodes for efficient oxidation. Based on experience and knowledge gained from application of the highly-effective Zimpro® wet air oxidation (WAO) technology, Siemens has developed an electrooxidation process to address the needs of refinery and petrochemical spent caustic treatment. This new process Zimpro® electro-oxidation uses electrically conductive boron doped diamond (BDD) electrodes, enabling efficient oxidation of organic and inorganic compounds that are dissolved in spent caustic. The system's flexible, modular design is capable of treating highly-contaminated spent caustic streams typically generated by both refineries and petrochemical plants in producing clean fuels and chemicals. Treatment using Zimpro electro-oxidation produces an effluent that is amenable to traditional wastewater treatment processes. The Zimpro electro-oxidation technology performs oxidation in a unique way, using electricity passed across BDD electrodes to produce oxidation reactions at nearambient conditions. The oxidation potential is very high, allowing for polishing to end-of-pipe requirements in the wastewater plant. Unlike other advanced oxidation processes, no strong and expensive oxidizing chemicals are required to be stored on- site, and the oxidation reactions only occur when electricity is applied to the electrodes. The heart of the Zimpro electro-oxidation process is based on a reactor that contains high-purity, electrically-conductive, solid polycrystalline BDD electrodes. These specialized diamond electrodes generate hydroxyl radicals that, when combined with the chemically inert nature of the synthetic diamond, provide a longlasting, efficient electrode for challenging oxidation applications like refinery and petrochemical spent caustics.
