摘要： There is disclosed a treatment for controlling the deposition of scale imparating species on the structural surfaces of steam generating systems, wherein the aqueous medium is maintained at a pH which minimizes magnetite solubility, comprising the use of a combination of an organic amine and a nonionic polymer having the structure:

wherein R 1 is H or lower (C 1 -C 4 ) alkyl, R 2 is (CH 2 -CH 2 -O) n ,

or a mixture of both, n is an integer of from 1 to about 40, and R 3 is H, lower (C 1 -C 4 ) alkyl or an acetate.

摘要： A method for controlling the deposition of scale imparting precipitates on the structural surfaces or hardness in steam generating systems comprising the use of a water soluble polymer having the structure

wherein E is the repeat unit remaining after polymerization of an alpha, beta ethylenically unsaturated compound.
This polymer may also be used in concert with topping agents such as, for example, phosphoric acids, phosphonic acids, polyvalent metal salts, metal chelating agents and oxygen scavengers.
