| 摘 要： | 炼油厂酸性水来自常减压、催化裂化、焦化和油品加氢过程,含有硫化氢、氨、油、酚、氰、悬浮物等污染物,早期采用的处理方法大多为空气氧化法和常压汽提法,目前以单塔加压侧线抽出汽提工艺和双塔加压汽提工艺为主,但小水量、低浓度酸性水的处理正在向高效微生物技术、化学氧化脱硫-生物脱氮技术等个性化技术发展。

| Abstract: | Sour water coming from atmosphere and vacuum distillation, fluid catalytic cracking, coking and hydrotreating processes in refineries typically contains such pollutants as H2S, ammonia, oil, phenol, cyanogen and suspending particles. The air oxidation and atmospheric stripping methods were applied for treating sour water originally. However, the single column pressurized stripping with side - draw and double column pressurized strip- ping are primarily used in nowadays. The characteristic technologies such as microbial treating technique with high efficiency and chemical oxidation desufurization - - biological denitrogenation techniques are becoming the development trend for treating sour water with minimum water and low concentration. |
