waste lye |
| Remarks： |
Alkali wash is an important treating method for gasoline, kerosene, diesel and other liquid hydrocarbons. However, the waste lye is one of the main pollutants in refineries.
FRIPP has successfully developed the mild wet oxidation (WAO)—stage intermittent activated sludge (SBR) combined process (including three patents and exclusive technologies for WAO reactor, recycling cooler, automatic control, and etc.). This combined process is a good approach to the treating of waste lye in refineries.
With this technology, the 2-valent sulfur can be transformed into sulphate and sulphite under mild temperature and pressure, and the contents and discharging of hydrogen sulfide and the total non-methane hydrocarbons are much lower than the limits stipulated in the Overall discharging standard for air pollutants. At the same time, the compounds, which is difficult to be removed via biodegradation, are oxidized into low molecule organic acids/aldehyde, and etc that can be easily biodegraded, which greatly increased the biology of the waste lye. Besides, the COD content and volatile phenols in waste lye are greatly decreased, COD is lower than 500mg/L and the volatile phenol is lower than 10 mg/L in the water outflow.
This technology has been applied in Daqing Petrochemical Works, Anqing Petrochemical Works, Dalian Petrochemical Company and etc. |
