Title:
METHOD OF TREATING WASTE CAUSTIC SODA
Document Type and Number:
WIPO Patent Application WO/2011/002138
Kind Code:
A1
Abstract:
Disclosed herein is a method of treating waste caustic soda, including: neutralizing waste caustic soda produced by an oil refining process using sulfuric acid; and wet-air-oxidizing the neutralized waste caustic soda. Since the waste caustic soda produced by an oil refining process can be treated at medium temperature and pressure using a wet air oxidation method, costs can be reduced. Further, the wet air oxidation method does not require high-cost equipment compared to other treatment methods, such as incineration, evaporation and concentration, and the like, and fuel consumption can be reduced. Moreover, since the equipment has a simple structure, maintenance costs can be reduced.
