“…Therefore, the occurrence of CaCO 3 scaling on electrode with galvanostatic polarization current of −65 μA/cm 2 shown in Figure and Figure is attributed to the higher cathodic current density. Accordingly, the CaCO 3 scaling can be only promoted by the cathodic reaction rather than the anodic reaction, which provides comprehensive and direct evidence to support the mechanism proposed in the literature, i. e., the corrosion enhanced CaCO 3 scaling should be attributed to the increased local pH caused by the cathodic reaction …”

“…Beside the environmental factors mentioned above, the effect of corrosion process on CaCO 3 scaling cannot be ignored because it can change the local ionic strength and pH of the solution at the metal/solution interface and, consequently, the CaCO 3 scaling process. Zhu et al.’s work found that corrosion process can affect the interfacial CaCO 3 scaling process by inducing rapid nucleation. Harri, Elbeik, Yan and Deslouis et al have also found the promoted CaCO 3 formation under cathodic polarization, and pointed out the significant effect of elevated electrolyte pH (“alkalization”) near the cathode.…”

The influencing mechanism of the cathodic and anodic reactions in the corrosion process of carbon steel on CaCO 3 scaling was studied by galvanostatic polarization, and explained by potentiodynamic polarization, and electrochemical calculation mathematical analysis on the Oddo-Tomson saturation index. The results reveal that the increased local pH caused by the higher cathodic current density is the only reason for enhanced CaCO 3 scaling. A critical corrosion rate due to the diffusion effect of OH À , above which the corrosion process can enhance the CaCO 3 scaling is reported. This research highlights the practical significance of corrosion related critical phenomenon for CaCO 3 scaling in the deoxidized oilfield injection water system.

“…Scaling on the cathode surface of an electrocatalytic oxidation device would reduce the output current of the device, greatly reducing the degradation efficiency to organic pollutants, until the device cannot operate normally. The deposition of these scaling substances on metal surfaces can also cause problems, such as local overheating and under-scale corrosion [10], which shortens the service life of the equipment.…”

The formation of CaCO3 crystals on the cathode surface and the scale-inhibition performance of scale inhibitor 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) on the cathode surface were studied by methods of solution analysis, gravimetric analysis, SEM, FTIR, and XRD techniques. They were then compared with the results of the formation and suppression of CaCO3 crystals in aqueous solution. PBTCA had a good solution-scale-inhibition performance and good lattice-distortion effects on CaCO3 crystals in solution, which could change the CaCO3 from calcite to vaterite and aragonite crystals. The solution-scale-inhibition efficiency exceeded 97% when the PBTCA concentration reached 8 mg/L. Under cathodic polarization conditions, the surface-scale-inhibition efficiency of the cathode and solution-scale-inhibition efficiency near the cathode surface both exceed 97% at polarization potential of −1V. The addition of PBTCA significantly reduced the amount of CaCO3 crystals formed on the cathode surface and had good surface and solution-scale-inhibition effect. However, the lattice-distortion effect of PBTCA on CaCO3 crystals disappeared on the cathode surface, and the resulting CaCO3 contained only calcite crystals. The high-scale-inhibition effect of PBTCA under cathodic polarization was mainly due to the inhibition of the formation of calcium carbonate crystals by PBTCA, and not because of the lattice distortion of CaCO3 crystals.

“…The tested synthetic waters served as the interpreter and were found in an offshore oilfield. The obtained water on a large scale contains a large quantity of Ca 2+ and HCO 3 −1 [100]. However, at a higher temperature (90-110 • C), a high PGLU concentration (160-200 mg L −1 ) was required to prevent the formation of scale.…”

In the present time, more often, it has been seen that scaling has grown as widely and caused problems in the oilfield industry. Scaling is the deposition of various salts of inorganic/organic materials due to the supersaturation of salt-water mixtures. Many works have been proposed by researchers using different methods to solve the problem, of which scale inhibition is one of them. The scale inhibitors, particularly for antiscaling, have derived from natural and synthetic polymers. Among different polymers, inorganic and organic compounds (polyphosphates, carboxylic acid, ethylenediaminetetraacetic acid (EDTA), etc.) can effectively manage the oilfield scales of which many are toxic and expansive. Scale inhibitors of alkaline earth metal carbonate and sulfates and transition metal sulfide are commonly used in oilfield applications. Scale inhibition of metallic surfaces is an essential activity in technical, environmental, economic, and safety purposes. Scale inhibitors containing phosphorus appear to have significant achievements in the inhibition process despite its toxicity. However, phosphorus-based inhibitors can serve as supplements prompting eutrification difficulties. Besides these increasing environmental concerns, green scale inhibitors are renewable, biodegradable, and ecologically acceptable that has been used to prevent, control, and retard the formation of scale. Considering the facts, this review article summarized the concept of scale, various green scale inhibitors, types, mechanisms, comparative performance, significance, and future aspects of green scale inhibitors, which will shed light and be helpful for the professionals working in the oil and gas industries.
