Technology and Equipment for Wet Oxidation of Alkali Residue

Release time：2017-04-10 17:20:22 source：

Petrochemical alkali residue is a petrochemical enterprises have a bad source of pollution. Waste alkali residue mainly from the liquid hydrocarbon base refining process, gasoline caustic washing process, diesel alkaline washing process, ethylene plant ethylene cracking gas alkaline washing process. The type and concentration of pollutants vary greatly depending on the type of processing crude oil and the processing process. The main pollutants are Na2S, thiol, thioether, thiophenol, thiophenol, phenol, naphthenic acid and so on. In addition to the unbearable stench, the excess COD and BOD values of the waste residue will also have an impact on the downstream sewage treatment plant. So take cost-effective, advanced and reliable alkali residue treatment technology, to promote the petrochemical enterprises to achieve the goal of discharge standards.

"Petrochemical alkali residue and waste water treatment technology" by the petrochemical Fushun Petrochemical Research Institute of Environmental Protection research and development of proprietary technology.

The technology can be in the more moderate conditions, the oxygen in the air as the oxidizing medium, the oxidation of refinery catalytic gasoline waste lye, liquid hydrocarbon waste alkali, mixed waste alkali and ethylene cracked waste alkali and other high concentrations of wastewater. The waste of organic matter in the decomposition of organic matter to achieve the purpose of dehumidification, deodorization, effluent sulfide concentration of less than 5mg / L, and the environment does not cause secondary pollution.

The main equipment of the technology includes wet air oxidation reactor and circulating cooling tower. The system adopts automatic control, which has the characteristics of simple process, small installation area, low investment and running cost and simple operation. The technical process and engineering technology is mature, is the first domestic, to achieve the advanced level of similar devices abroad. And has been "CN 98121081.3," CN 98121082.0 "two patents.

So far, the technology has been successfully used in Shanghai, Anqing, Daqing, Changling, Qingdao, Nanjing, Jiujiang, Jingmen, Luoyang, Zhanjiang, Zhenhai, Maoming, Hainan and other more than 20 petrochemical enterprises refining, Lye industrial processing, and achieved good treatment results, access to significant environmental benefits and social benefits. Recently, the "refinery alkaline residue and waste water treatment technology industrial applications" was named the provincial science and technology Association sixth "Jinqiao project" outstanding project second prize.
