| titleOfInvention | Degradation-resistant scale inhibitors |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of reducing scale formation in technological processes. Disclosed is a method for reducing aluminosilicate containing scale in a Bayer process, which includes identifying a Bayer process equipment surface that is subject to scale formation during the Bayer process; contacting the identified Bayer process equipment surface with an amount of a scale inhibiting composition effective to form a treated surface that is more resistant to scale formation upon subsequent contact with a Bayer process stream than an otherwise comparable untreated surface; contacting the treated surface with the Bayer process stream; wherein the scale inhibiting composition comprises an aqueous solution of one or more water-soluble salts having at least about 0.004 % of total dissolved salts and a silicon-containing compound having one or more -Si(OR) n groups, where n is 3 and R is C 1 -C 20 alkyl, and the silicon-containing compound is a reaction product of polyethylenimine, a silane selected from 3-chloropropyltrimethoxysilane and 5,6-epoxyhexyltriethoxysilane, and a nitrogen-reactive compound selected from 1-chlorooctane, benzyl chloride, propylene oxide, 1,2-epoxy-octane, 1,2-epoxydodecane and propylene chloride, wherein the organosilicon compound is resistant to degradation in process streams for the extraction of alumina at process temperature from 100 to 265 °C. n EFFECT: technical result: the proposed method allows to reduce or eliminate the scale formation in the processes of extracting alumina at high temperatures, wherein the scale-inhibiting composition is resistant to degradation. n 16 cl, 1 dwg, 6 tbl, 7 ex |
