ABSTRACT:
Method of preventing deposits of dissolved inorganic salts on heated surfaces, such as tubular heat exchangers, is carried out by adding a deposit-preventing agent to the water before contact with the heated surfaces. Compounds complexing with cations are combined with anionic substances which are capable of salt formation with complex bound cations to form additive compositions which are added to the water in the zone near the walls of vessels or tubular heat exchangers subject to deposit incrustation. Such compositions are formed from cation-complexing compounds comprising a mixture of sulfurous acid esters of di- and/or polysaccharides and carboxymethyl cellulose as cation-complexing compounds, which mixture is combined with anionic substances comprising sulfonated fat by alcohols and/or fatty acids in the weight ratio having a range of from about 80 parts by weight cation-complexing compound to about 20 parts by weight anionic substance to (2) about 95 parts by weight cation-complexing compound to about 5 parts by weight anionic substance, the preferred weight ratio being 85:15 to 90:10 of cation-complexing compound; anionic substance, respectively. These compositions are added to the water in amounts ranging from 10 to 60 milligrams per liter, preferably 20 to 30 milligrams per liter.
