影响硫酸钡阻垢效果因素实验研究

为了研究硫酸钡阻垢效果的影响因素，实验中采用静态阻垢法对筛选出的ZX–101、TH–1 以及TH–607B 3
种钡（锶）阻垢剂，分别开展了温度、矿化度、Ba2+ 浓度以及SO2-4 浓度对硫酸钡阻垢效果影响实验。实验结果表明：3
种阻垢剂均表现出较好的阻垢性能，能够有效阻止硫酸钡结垢。随着温度与体系矿化度的升高，3 种阻垢剂的阻垢率
呈现出先增加后减小的规律，且阻垢率随阻垢剂浓度的增加而增加。当温度为65 ℃、SO2-4 浓度为0.55 g/L、矿化度
为73 g/L、阻垢剂浓度为0.10 g/L 时，溶液中的Ba2+ 浓度从0.64 g/L 增加到1.28 g/L 的过程中，3 种阻垢剂的阻垢率
逐渐降低，分别从96.55%、97.65%、98.04% 下降为82.80%、87.83%、84.49%。当Ba2+ 浓度为0.8 g/L、阻垢剂浓度为
0.08 g/L、溶液中SO2-4 浓度从0.10 g/L 增加到0.60 g/L 时，3 种阻垢剂的阻垢率分别从90.64%、96.49%、93.57% 增加到
99.79%、99.28%、99.79%，随后开始下降，最终下降为93.72%、91.09%、80.06%。

Experimental Study on Factors Affecting the Effect of Barium Sulfate Scale Inhibition

In order to study the factors that affect the effect of barium sulfate scale inhibition，three kinds of scale inhibitors
named ZX–101，TH–1 and TH–607B that resistance barium sulfate（strontium sulfate）were screened out to make experiments
of temperature，salinity，concentration of Ba2+ and SO2-4 impact on barium sulfate separately by static scale inhibition method.
The results show that these three inhibitors have shown great performance for barium sulfate scale，they can prevent scaling
of barium sulfate effectively. Their inhibition efficiency first increase and then decrease with the increasment of temperature
and salinity，and when the inhibitor concentration increases the inhibition efficiency increases. When the temperature is 65 ℃，
SO2-4 concentration is 0.55 g/L，salinity is 73 g/L，inhibitor concentration is 0.1 g/L and the concentration of Ba2+ increases from
0.64 g/L to 1.28 g/L，these three kinds of scale inhibition efficiency gradually decrease，respectively from 96.55%，97.65%，
98.04% down to 82.80%，87.83%，84.49%. While Ba2+ concentration is 0.8 g/L，inhibitor concentration is 0.08g/L and the
concentration of SO2-4 increases from 0.10 g/L to 0.60 g/L，their inhibition efficiency increase from 90.64%，96.49%，93.57%
to 99.79%，99.28%，99.79%，and then begin to decline，eventually drop to 93.72%，91.09%，80.06%.
