“…SEM pictures and XRD analysis with the presence and absence of inhibitor are illustrated in Figures and , respectively. In the absence of inhibitor, as shown in Figure that CaCO 3 precipitation is pure calcite rather than aragonite or vaterite, characterized by the diffraction peaks at C(012), C(104), C(006), C(110), C(113), C(202), C(018), and C(116) …”

Polymer scale inhibitors have been widely used to reduce the loss caused by mineral scaling in circulating cooling water systems. In this article, four maleic acid‐based copolymers [hydrolyzed polymaleic anhydride (HPMA)‐AEO] containing different fatty alcohol polyoxyethylene ether (such as AEO‐9, AEO‐10, AEO‐15, and AEO‐20) are prepared by the way of free‐radical copolymerization and characterized using Fourier transform infrared (FTIR), 1H NMR, and gel permeation chromatographic (GPC) techniques. The effects of HPMA‐AEO on CaCO3 scale are studied in several aspects (such as dose, Ca2+ concentration, temperature, inhibition time, pH, the ratio of EO:carboxyl, and the relative supersaturation of CaCO3 solution) by static experiments. The CaCO3 scaling process with dosing of HPMA‐AEO‐9 is investigated under dynamic tests. CaCO3 deposits and precipitate in the presence of HPMA‐AEO‐9 are analyzed using scanning electronic microscope (SEM) and X‐ray diffraction (XRD). The results show that the performance of HPMA‐AEO against CaCO3 scale highly depends upon the ratio of EO:carboxyl; the introduction of AEO group can significantly improve the performance of HPMA‐AEO to tolerate high alkalinity, high hardness, and high temperature; the presence of HPMA‐AEO‐9 can obviously affect the CaCO3 scaling process on the tube wall through interfering with nucleation process and crystal growth process and significantly alter the surface morphology and crystal form of CaCO3 deposits. © 2019 Wiley Periodicals, Inc.

The aqueous extract of Gypsophila aretioides roots as a “green” or eco-friendly inhibitor of carbonate calcium formation was investigated. The presence of chelating factors such as polyphenol compounds and foaming agents in the plant extract was assessed. Atomic absorption spectroscopy (AAS) demonstrated the ability of G. aretioides extract for dissolution of the carbonate calcium precipitates. Moreover, conductivity measurements revealed that the G. aretioides extract could efficiently retard sedimentation of carbonate calcium from a brine solution of calcium ions exposed to carbonate ions by adding Na2CO3 to the system solution. In addition, chronoamperometry was performed for a period of 3 h by polarizing the steel electrode to -0.9 V (vs. SCE) at 40°C. The presence of G. aretioides extract at a concentration of 10% (w/v) in chronoamperometry prevented the precipitation of CaCO3 on the steel electrode surface. This was confirmed by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analyses which showed an absence of precipitates and lack of calcium ions on the steel electrode after 3 h chronoamperometry, respectively. However, further studies are required in order to amend the characteristics of G. aretioides extract to render it more applicable as an eco-friendly, cost-effective, anti-scale agent for a wide range of industrial applications.

“…Along with the aforementioned considerations, interest has turned to naturally occurring scale inhibitors (Chaussemier et al 2015;Menzri et al 2017;Reno and Endaryanto 2017). Modified natural plant extracts such as insulin-modified compounds have been studied for their applications as scale inhibitors (Kırboga and Öner 2012;Rahul et al 2014;Zhang et al 2016a). Also, natural products that contain substantial amounts of polyphosphates, carboxylic acid groups, alcohol, and aromatic amines with potential functionalities for adsorption or anti-scaling effect have considered (Abdel-Gaber et al 2011;Chaussemier et al 2015;Khamis et al 2018).…”

State of the art of synthetic threshold scale inhibitors for mineral scaling in the petroleum industry: a review

Inorganic scale deposits are a major water-related problem encountered in producing oil and gas wells. The harshness of scale deposits is dependent on the field operating conditions. Scale deposits can vary from mild scaling tendencies to extreme. In general, the scale deposit will cause a reduction in formation pores, declining productivity and eventually blockage of the wellbore and hence unexpected downtime if it is allowed to persevere. To overcome this, the productivity of an oil and gas well is ensured by handling scale deposits via removal or prevention methods. Scale prevention is the best and cost-effective method for handling scale deposits that ensures production continuity. Inhibition through "threshold" scale inhibitor treatment is the most common method that is proven to prevent or reduce likely deposits. This paper examines the art of synthetic scale inhibitors, in particular, threshold scale inhibitors in oil and gas production. It discusses the chemistry of those inhibitors, inhibition mechanisms, treatment methods and key properties for their applications. It also highlights the chemistry of the synthetic routes often used to produce them in the laboratory and/or industry. Finally, it highlights the environmental concerns for the applicability of threshold scale inhibitors.
