H_2O_2 Cuts Haz Waste Disposal Costs for Refinery

摘要

For three years, a refinery in the southern United States used peroxidation to treat spent caustic, allowing it to be used in a biological treatment system for pH control rather than shipped off site as waste. The result was a savings of 27 cents per gallon for treatment vs. off-site disposal, or $135,000 per year for 500,000 gallons of spent caustic. The peroxidation treatment system was supplied by Degussa Corp., Allendale, N.J.
