Yangzi Petrochemical waste alkali liquid unit has come on stream

  • A high temperature waste alkali liquor process unit of ethylene plant of Yangzi Petrochemical Company has currently come into operation. It can handle 4.6 tones of mixed waste alkali liquid per hour. With its completion, the inefficient waste alkali liquid handling problem of ethylene unit has been solved and waste treatment cost has been greatly cut down.

    A high temperature waste alkali liquor process unit of ethylene plant of Yangzi Petrochemical Company has currently come into operation. It can handle 4.6 tones of mixed waste alkali liquid which is from refining and ethylene units per hour. The completion of the revamp project is significant beneficial to the surrounding environment.

    The revamp project has incorporated Siemens’ advanced automatic high temperature wet oxidation process, and is designed by Beijing Petrochemical Design & Engineering Company. During waste alkali processing, carbon dioxide previously used in neutralization reaction is released and then routed to aromatic plant carbon monoxide unit as feed. With its completion, the inefficient waste alkali liquid handling problem of ethylene unit has been solved and waste treatment cost has been greatly cut down.
