“…experiments at different pH values were conducted by adjusting the pH (5,6,7,8,9) with hydrochloric acid and sodium hydroxide solutions. After that, His-SA-PASP and Arg-SA-PASP with different concentrations were added into the solution, and the temperature was kept at 80°C for 10 h. The calcium ions in the solution were titrated with ethylenediaminetetraacetic acid (EDTA) solution (0.01 mol L -1 ).…”

Amino acid modified polyaspartic acids were evaluated as calcium-scale inhibitors. Feasibility of scale inhibition experiments was analyzed by molecular dynamics simulation and Gaussian optimization, and the scale inhibition mechanism was theoretically analyzed. Scale inhibition performance was studied by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, static scale inhibition experiments, and electrochemical performance testing, which provided an experimental basis for the molecular dynamics simulation. The experimental results showed that Arg-SA-PASP has better scale inhibition and corrosion inhibition performance than His-SA-PASP. The scale inhibition effect increased with increasing concentration. Electrochemical tests indicated that Arg-SA-PASP is an excellent scale and corrosion inhibitor.

“…After cooling to room temperature, these supersaturated solutions were filtered and then dried in vacuum at 50 • C for 12 h. The concentration of Ca 2+ was titrated by an Ethylenediaminetetraacetic acid (EDTA) standard solution. The Ca 2+ retention efficiency was determined by the formula [24]:…”

The effect of NaCl at extremely high concentrations from 3.5 to 14 wt. % on the crystallization of CaCO3 was investigated in depth. The static test experiment verified that the Ca2+ retention efficiency (η) of NaCl on CaCO3 scale increased from 31.06% (3.5 wt. %) to 41.56% (14 wt. %). Based on the calculation of supersaturation rations, the high concentration of NaCl could reduce the activity coefficients of [Ca2+] and [CO32−], thus reducing the actual concentration of CaCO3. The CaCO3 deposition rate constants (k) showed that NaCl slowed down the rate of CaCO3 crystallization. The X–ray diffraction (XRD) testing disclosed that the growth of (1 0 4) and (1 1 0) faces from calcite was impeded, while the formation of (1 1 1) face from aragonite was induced by the increasing concentration of NaCl. The inductively coupled plasma optical emission spectrometry (ICP–OES) results indicated that Na+ could be doped into CaCO3, leading to the one–dimensional crystal growth. It was further proved that NaCl heightens the efficiency of the typical phosphate inhibitors (2–phosphonobutane–1,2,4–tricarboxylic acid (PBTCA) and 1–hydroxyethane–1,1–diphosphonic acid (HEDP)) on prohibiting the scale of CaCO3.

“…[9][10][11][12] It is generally believed that the main mechanism of scale inhibition includes: threshold effect, crystal distortion effect, dispersion effect, chelating effect, and so on. 15,16 However, these scale inhibitors will decompose and form phosphate acid due to the increase in temperature and react with calcium ions to form an insoluble calcium phosphate scale. 14 The first category is polyphosphate scale inhibitors, such as aminotrimethylenephosphonic acid, and 2-phosphonic acid 1, 2, 4-tricarboxylic acid, which have been widely used in the industrial production due to their outstanding scale inhibiting efficiency.…”

The CaCO 3 deposits exist widely in the petroleum industry, causing severe damage to the equipment and production. In this article, a novel environment-friendly terpolymer scale inhibitor Poly (maleic anhydride -acrylic acid -2-acrylamide -2-methyl propanesulfonic acid) (P(MA-AA-AMPS))-containing carboxylic acid group, sulfonic acid group, and amide group was synthesized. The structure and molecular weight were characterized by FTIR, 1 H-NMR, and GPC. The static scale inhibition experiment was conducted to study the influence of factors such as the dosage, monomer ratio, temperature, pH, Ca 2+ concentration, and HCO − 3 concentration on the scale inhibition performance of CaCO 3 . The results show that when the monomer ratio is 2.0:1.0:0.5 and the dosage is 20 mg L −1 , the maximum scale inhibition efficiency is 95.52%. Even when Ca 2+ concentration exceeds 1200 mg L −1 and temperature reaches 90 C, the scale inhibition efficiency is still larger than 80%. The results of SEM and XRD show that P(MA-AA-AMPS) interferes with the growth of CaCO 3 crystal by adsorption, dispersion, and chelation. The effect leads to changes in the morphology of CaCO 3 crystals, the size of which drops from 20-30 μm to 2-5 μm. The P(MA-AA-AMPS) can transform CaCO 3 from stable calcite crystals to unstable aragonite and vaterite. Finally, the formation of CaCO 3 scale is well inhibited.
