بررسی عمل‌کرد بازدارنده‌‌های بسپاری ضد رسوب با استفاده از روش شیمیایی تودۀ سیال در محلول استاندارد ASTM D1141

Scaling formation in industrial or domestic installations is an important economic and technical problem. In this study, the percentage of calcium carbonate deposition in the solution based on ASTM D1141 at different LSIs was investigated by using the chemical method. It was revealed that at LSI values greater than 1.8, the probability of CaCO₃ deposition is considerably increased. Therefore, at LSI = 2.2 the effect of concentration of different green-scaling inhibitors including homopolymers, copolymers and terpolymers on the CaCO₃ deposition process was investigated by chemical analysis method and the optimal concentration of scaling inhibitors was determined. For the inhibitors of polyacrylic acid homopolymer (PAA), poly maleic acid homopolymer (PMA), poly acrylic acid: 2-acrylamido-2- methylpropane sulfonic acid copolymer (AA/AMPS) and poly acrylic acid:2-acrylamido-2-methylpropane sulfonic acid: t-butyl acrylamide terpolymer (AA/AMPS/TBAA), the optimal inhibitory concentration was obtained at 5, 5, 2 and 2 ppm concentration, respectively by the chemical method of bulk analysis.
