摘　　要：介绍了水夹点技术的理论,同时给出该技术在M炼油厂的计算实例。首先确定初始浓度间隔图;通过浓度转移,确定最终浓度间隔图;以最大限度地进行各浓度间隔、各用水操作之间的水回用为前提,计算出新鲜水用水量、回用水量和各操作入、出口浓度,从而得到最小用水量;最后进行用水网络设计。该项目的实施可使该厂的用水量节约23%。The theory of water pinch point technology was presented and the calculation example of it in oil refinery M was provided. Firstly, the initial concentration-interval graph was determined, and then, through the concentration shift, the final concentration-interval graph was constructed; on the premise that the water between each concentration-interval and each water-using operation was maximumly reused, the requirement of freshwater and reused water, the inlet and outlet concentration of each operation were found through the calculation, and finally, the minimum freshwater demand was obtained; according to the above results, water-using network was designed. With the application of the said scheme, the freshwater demand for the said plant would reduce about 23%.

关 键 词：工业节水 水夹点技术 最小新鲜水用量
