Siemens, with numerous locations throughout the Americas, has developed an electro-oxidation 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. Siemens Water Solutions addresses water and wastewater needs of the oil and gas industry with a portfolio that includes physical and chemical separation, biological treatment, and complex hydrothermal technologies.
The Zimpro system’s flexible, modular design is designed to treat 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.
