Abstract

Abstract:

In order to study the influence of the combined action of multiple factors on the calcium carbonate scale inhibition，
100 mg/L of PESA screened out by static scale inhibition method were employed in the experimental research on the
factors affecting calcium carbonate scale inhibition. First，we studied the impact of inhibitor type，inhibitor concentration，
supersaturation，salinity，and pH on calcium carbonate scaling inhibition separately by single factor analysis. Then orthogonal
experiment was designed based on the experimental results of different factors. The experiment studied the combined action of
temperature，salinity，partial pressure of CO2 and pH. The result of the single factor analysis showed that the scale inhibition
rate of PESA decreased as supersaturation increased，and climbed up first and then declined slowly as salinity or pH increased.
Scale inhibition rate reached 95.85% at the critical salinity，which turned to be 50 g/L. And optimal inhibition rate was 90%
when pH varied from 6.5 to 8.0. The result of the orthogonal experiment showed that temperature was the key factor on scale
inhibition rate with 8.2 Xbar-R and 0.002 P. Followed by pH and CO2 partial pressure，the influence of salt content was negligible.
Finally，the optimum combination of influencing factors was obtained，and the analysis showed that 60 ℃，7.5 pH，
1.5 MPa CO2 partial pressure，5.5 g/L salinity would produce the best scaling inhibition result.

Key words: calcium carbonate, scale inhibition, temperature, pH, salinity, orthogonal experiment
