Estimating the term…
A chemical formulation and method are provided for the treatment of water to prevent, control or inhibit corrosion and/or deposits, particularly for the treatment of water in water distribution piping and equipment and associated heat exchangers and more particularly for the treatment of water in heat transfer equipment wherein water or steam is employed as the heat transfer medium. The method treats the water with at least one mono- or polyhydric alcohol. Optionally, the treatment formulation is a blend of mono- or polyhydric alcohols and further optionally includes one or more of a mixed molecular weight polyacrylic acid and/or at least one salt thereof; at least one chromium-free lignosulfonate, and at least one carboxylic acid and/or at least one salt thereof, the carboxylic acid being different from the poly acrylic acid.
A process of treating water to inhibit corrosion and/or deposit formation which process comprises adding to said water for the purpose of inhibiting said corrosion and/or deposit formation an effective amount of at least one mono or polyhydric alcohol wherein said monohydric alcohol has a molecular weight of from about 34 to about 142 and said polyhydric alcohol has a molecular weight of from 62 to about 496.
A chemical formulation which comprises:
A process of treating water to inhibit corrosion and/or deposit formation which process comprises adding to said water for the purpose of inhibiting said corrosion and/or deposit formation an effective amount of a composition consisting essentially of at least one mono- or polyhydric alcohol.
