Title The research on performance of conventional scale
inhibitors in low temperature
Abstract
The performance of five scale inhibitors (acrylic - hydroxypropyl acrylate copolymer,1-hydroxy ethylidene-1,1-diphosphonic acid produced by two different manufacturers, 2 - acrylamide - 2 - methyl propane sulfonic acid copolymer, amino trimethylene phosphonic acid) in low temperature was studied by static anti-scaling method. The performance of five inhibitors in low temperature was compared by a series of experiments, and the best dosage of scale inhibitors was found. The result of the tests showed that the efficiency of inhibitor has a saturation point with the growth of dosage. When the scale inhibitor dosage is 10mg/L, the inhibiting efficiency of all of the scale inhibition are higher. Comparing the anti-scaling efficiency of the five scale inhibitors in the low temperature under the dosage, 1-hydroxy ethylidene-1,1-diphosphonic acid anti-scaling performance is the best, and the worst is 2 - acrylamide - 2 - methyl propane sulfonic acid copolymer.
