摘要
对炼油厂酸性水的来源和种类进行分类说明,简要介绍了单塔低压汽提、双塔加压汽提和单塔加压侧线抽出汽提等3种酸性水汽提工艺的典型流程及其区别。针对近年国际上主流的而国内较少采用的循环泵回流的单塔低压汽提工艺进行重点阐述,按流程顺序对酸性水闪蒸罐、酸性水储罐、酸性水汽提塔、循环泵回路等各主要设备做了较为详细的工艺设计参数的分析,并探讨了设计上的着眼点和基本原则;指出在设计过程中选择合理、优化的工艺参数是酸性水汽提装置高效、平稳运行的关键。
The sources and types of refinery sour water (also known as sulphur-bearing waste water) were introduced and three typical stripper unit process flows for treating the sour water were briefly described, namely Low Pressure Single Stripper process, High Pressure Two-column Stripper process and High Pressure Single Stripper with Side-draw process. Low Pressure Single Stripper with Pumparound process has been the prevailing configuration employed internationally nowadays which is, however, less common in China. Design parameters for all the main pieces of equipment in the process were studied and discussed in process sequence, including sour water flash drum, sour water storage tank, sour water stripper, pumparound loop and so forth. It is paramount to determine appropriate and optimal process parameters during design phase for an efficiently and smoothly operated sour water stripper unit.
