摘要/Abstract

摘要： 在炼化企业中,不同的炼油工艺都会产生一定数量和质量的废水。基于物质流分析方法的跟踪观察模型,将所有用水过程整合到水平衡系统中,建立炼化企业用水网络优化模型和评价指标体系。以我国某炼化企业为例,构建了企业各生产工序的用水网络模型,确定了目前用水网络系统中存在的最小水耗问题,依此方法进行用水优化和评价分析。结果表明,采取用水系统优化措施后,新鲜水消耗量可降低26.90%,污水排放量可降低 84.42%,水资源效率提高15.34%。

Abstract: In oil refining enterprises, different oil refining process would produce a certain amount and quality of wastewater. Based on the tracking model of material flow analysis method, all the water process was integrated into the water balance system, and the optimization model and evaluation index system of the water supply network were established. Taking the oil refinery in China as an example, the water network model of the oil refining production process was constructed, and the minimum water consumption problem of the current water system was determined. The method was optimized and evaluated. The results showed that the fresh water consumption could be reduced by 26.90% and the sewage discharge could be reduced by 84.42% after taking the water system optimization measures. Waterenvironmental efficiency increased by 15.34%.
