Abstract:

To prevent scaling in low temperature，phosphine carboxylic acid copolymer has been prepared. Through screening and field application，the frequent scaling of cryogenic equipment is avoided，and the long-term safety operation of the low temperature water system can be guaranteed and water resources can be economized.

Key words: circulating cooling water, scaling in low temperature, operation in deep cold
