Abstract:

Aiming at the problem of low-temperature scaling in circulating water systems at oxygen producing factories，suitable water treatment chemicals and water stabilizing technology have been used for avoiding the blocking phenomenon occurring to some critical equipments in pre-cooling systems at oxygen producing factories，such as air cooling towers and water cooling towers etc. The practice proves that the water treatment chemicals used and corresponding techniques have pretty good efficiencies in ensuring the long-term running with stability and safety for the circulating water systems at oxygen producing factories.

Key words: pre-cooling system, air cooling tower, water cooling tower, low-temperature scaling
