Abstract:

The water-saving and emission-reduction work of the circulating cooling water systems in refining and chemical enterprises has received increasing attention. The features of every link of water supply and drainage in circulating cooling water systems and the main water-saving measures and techniques applied to the present circulating cooling systems are discussed. The advantages and disadvantages of various water-saving measures and techniques are analyzed. In addition，the water-saving and emission-reduction work of the circulating cooling water systoms in refining and chemical enterprises are predicted.

Key words: refining and chemical enterprises, circulating cooling water, water saving
