摘要： The prevention of corrosion on the surfaces of metallic pipes, heat exchangers, and the like which are in contact with industrial cooling waters, and particularly industrial cooling waters containing low levels of hardness is controlled utilizing a corrosion inhibiting amount of a composition including an alkali metal silicate, a hydroxycarboxylic acid or its water soluble salts, an organophosphonate, and a water soluble polymer which acts as a dispersant. Superior corrosion inhibition is achieved using the compositions of this invention as corrosion inhibitors, particularly in cooling water systems employing mild steel metallurgy.

摘要： A substantially water-insoluble, slightly cross-linked, partially neutralized, hydrogen-forming polymer composition consisting essentially of(a) from about 50 mole percent to 99.999 mole percent of polymerizable acid group-containing monomers, and(b) from about 0.001 mole percent to 10 mole percent of a water-soluble polyamine;said hydrogel-forming polymer composition having been formed by reacting a water-soluble acid group-containing vinyl polymer with a water-soluble polyamine at a temperature sufficient to convert the substantial portion of the amino groups of the water-soluble polyamine into amido groups.

摘要： An autocycle method to control a cooling water system comprising the steps of: a) adding a treatment product to said cooling water system, with said treatment product comprising inert tracer and tagged treatment polymer in a set proportion; b) providing a sufficient number of fluorometers, c) using said sufficient number of fluorometers to measure the fluorescent signal of said inert tracer and the fluorescent signal of said tagged treatment polymer in the water from the cooling water system; d) using these measured fluorescent signals from step c) to determine the amount of said tagged treatment polymer present in said cooling water system; e) comparing the amount of said tagged treatment polymer present to the amount of tagged treatment polymer being fed into the system to determine the consumption of said tagged treatment polymer; and f) using said consumption of said tagged treatment polymer to control the concentration cycles of said cooling water system, with the proviso that said control is implemented by linking any or all of the following parameters i) the flowrate of the make-up water to the cooling water system; ii) the flowrate of the treatment product comprising inert tracer and tagged treatment polymer, iii) frequency and amount of blowdown flowrate from the cooling water system; iv) overall water flowrate through the cooling tower; v) overall volume of water in the cooling tower; and vi) composition of makeup water; to the consumption of said tagged treatment polymer, with the provisos that: &agr;) the minimum flowrate of treatment product comprising inert tracer and tagged treatment polymer must be sufficient to supply the cooling water system with the requisite amount of tagged treatment product; and &bgr;) when control is implemented by linking flowrates, the flowrates are balanced.
