Wet-air oxidation technology is enabling a petrochemical company in Taiwan to increase production while protecting the environment. This 30-year-old technology has found a new niche at three refineries owned and operated by Chinese Petroleum Corporation to treat spent caustic liquor derived from ethylene production and other sources. Wet-air oxidation destroys sulfides, mercaptans, phenols and other difficult-to-treat pollutants, or converts them to biodegradable constituents. Such highly colored, odorous liquors are not amenable to biological treatment; however, effluent from wet-air oxidation at CPC is water-clear and treated easily by the company's biological wastewater treatment system.
