乙烯裂解气碱洗废碱液处理技术的开发及工业应用
|
摘要
介绍了乙烯裂解气碱洗废碱液处理技术的开发及工业应用情况。开发的以湿式氧化(WAO)技术为核心的"湿式氧化-酸化中和"处理技术,工业化装置运行稳定,出水S2-小于1 mg/L、COD去除率大于93%,达到设计要求。该套装置的成功应用,实现了乙烯废碱液处理技术和装置的国产化,为企业清洁生产提供了技术保障,社会效益和经济效益显著。
The development and industrial application of the treatment technology for the spent caustic containing sulfur from caustic scrubbing process of cracking gas in ethylene plant were described. The "Wet air oxidation and acidification neutralization" technology was developed. The industrial unit with the technology operated stably. The S2-of this unit effluent was less than 1 mg/L, and the COD removal rate was more than 93%. The successful application of this unit has realized the localization of technology and equipment for this spent caustic treatment, and provided technical support for cleaner production. Significant social and economical benefits have been achieved.
