“…However, most of the phosphonic acid scale inhibitors currently on the market, such as amino trimethylene phosphonic acid (ATMP) and ethylene diamine tetramethylene phosphonic acid (EDTMPA), have poor compatibility with calcium ions and will cause complex precipitation . On the basis of the above problems, the research and application of polymers modified by different groups and some multifunctional binary and ternary water treatment agents have become the trend of research and application. − …”

A hydrophilic terpolymer scale inhibitor (AA–APES–HPAY) was prepared by free radical polymerization with acrylic acid (AA), hydroxypropyl acrylate modified by 2-phosphonobutane-1,2,4-tricarboxylic acid (HPAY), and allyl polyethoxyammonium sulfonate (APES) as monomers in aqueous solution. The structure of the copolymer was characterized by Fourier transform infrared spectroscopy and hydrogen nuclear magnetic resonance spectroscopy. The effectiveness of AA–APES–HPAY depends upon the monomer mass ratio, temperature, and amount of initiator. According to the oil field scale prevention performance test method, the inhibition efficiency of CaCO3 reached 89.2% at a level of 21 mg/L and the CaSO4 inhibition was 92.4% at the low level of 3 mg/L. The surface morphology and crystal form of the scale and the principle of scale inhibition were analyzed by scanning electron microscopy and X-ray powder diffraction. The scale inhibition mechanism is proposed and analyzed in detail.

Theoretical Studies of a Silica Functionalized Acrylamide for Calcium Scale Inhibition

et al. 2022

The calcium carbonate (CaCO3) scale is one of the most common oilfield scales and oil and gas production bane. CaCO3 scale can lead to a sudden halt in production or, worst-case scenario, accidents; therefore, CaCO3 scale formation prevention is essential for the oil and gas industry. Scale inhibitors are chemicals that can mitigate this problem. We used two popular theoretical techniques in this study: Density Functional Theory (DFT) and Ab Initio Molecular Dynamics (AIMD). The objective was to investigate the inhibitory abilities of mixed oligomers, specifically acrylamide functionalized silica (AM-Silica). DFT studies indicate that Ca2+ does not bind readily to acryl acid and acrylamide; however, it has a good binding affinity with PAM and Silica functionalized PAM. The highest binding affinity occurs in the silica region and not the –CONH functional groups. AIMD calculations corroborate the DFT studies, as observed from the MD trajectory that Ca2+ binds to PAM-Silica by forming bonds with silicon; however, Ca2+ initially forms a bond with silicon in the presence of water molecules. This bonding does not last long, and it subsequently bonds with the oxygen atoms present in the water molecule. PAM-Silica is a suitable calcium scale inhibitor because of its high binding affinity with Ca2+. Theoretical studies (DFT and AIMD) have provided atomic insights on how AM-Silica could be used as an efficient scale inhibitor.

“…Commonly used sulfonic acid monomers are 2-acrylamide-2-methylpropanesulfonic acid (AMPS), sodium styrene sulfonate (SSS), and so on. The efficiency of the treatment agents such as IA-AMPS, 17 MA-AMPS-HPA, 18 MA-SSS-HPal (acidified pozzolans) 19 to inhibit CaCO 3 scale are above 82% and reported to show good heat and salt resistance performance. In response to the call for green concept, alkyl epoxy carboxylic acid, an environmental friendly antiscalant, is modified to make use of the ethylene oxide group (EO, CH 2 CH 2 O ) to improve the water solubility of the scale inhibitor to make it suitable for high pH, high alkalinity, high temperature conditions.…”
