Water Quality Analysis of a 300 Mvar Large-Scale Dual Internal Water Cooling Synchronous Condenser External Cooling System and Exploration of Optimal Water Treatment Agent Dosage at Different Temperatures

The external cooling water system of a 300 Mvar dual internal water cooling synchronous condenser at a certain ultra-high voltage converter station continued to exhibit significant scaling and corrosion, even with regular addition of scale and corrosion inhibitors. To solve this problem, the external cooling water of the synchronous condenser was sampled and tested periodically, with the main test items including conductivity, pH value, turbidity, hardness, alkalinity, and other water quality parameters directly related to corrosion and scaling. The trends of these parameters over time were also analyzed. The results showed that as the operation time increased, the cooling water became concentrated during multiple circulation cycles, and the various dissolved or suspended substances underwent a certain degree of enrichment. However, the addition of scale and corrosion inhibitors did not dynamically adjust according to the changes in water quality, and there was always an excessive dosage. Thus, using the external cooling water as the experimental sample, static scale inhibition tests and rotating coupon corrosion tests were conducted to evaluate the scale and corrosion inhibition performance of the commercial AS-582 scale and corrosion inhibitor used at this ultra-high voltage converter station under different conditions. Considering the more obvious corrosive tendency of this water sample, the focus was on testing its corrosion inhibition performance. When the dosage was 600 ppm, the scale inhibition effect was optimal, with an inhibition rate of 92.15%. The corrosion inhibition effect of this scale and the corrosion inhibitor were significantly related to water temperature. At 25 °C, when the dosage was 500 ppm, the corrosion inhibition effect was optimal, with an inhibition rate of 86.79%. However, when the temperature increased to 40 °C, the corrosion inhibition effect under each dosage was significantly worse, unable to meet the requirements, and the use of other corrosion inhibitors in combination was necessary. This work will provide a reference for the scientific use of scale and corrosion inhibitors.

Synthesis and evaluation of an environmentally friendly phosphorus-free and nitrogen-free polymer as a scale and corrosion inhibitor

Polyepoxysuccinic acid (PESA) was modified by glycidyl (Gly) to obtain a phosphate-free and nitrogen-free polymer (Gly-PESA), and its scale and corrosion inhibition properties were studied.The effects of Gly-PESA concentration, calcium ion concentration and temperature to scale inhibition performance were studied by static scale inhibition method. The corrosion inhibition performance of Gly-PESA was studied by static weight-loss method. The morphology and structure of calcium scale and steel surface were characterized by spectroscopic and microscopic methods. The scale inhibition efficiency of Gly-PESA for CaCO3 and CaSO4 was 98.06% and 92.6%, respectively. Under the same experimental conditions, the scale inhibition effect of Gly-PESA was obviously better than that of PESA. Gly-PESA could effectively inhibit the growth of CaCO3 and CaSO4 crystals and cause their crystal lattice distortion or crystal dispersion. The corrosion inhibition efficiency of Gly-PESA for carbon steel was 78.17%. The adsorption of Gly-PESA on the surface of the steel test piece followed Langmuir adsorption isotherm, and formed a protective film, which increased the corrosion resistance of the steel test piece, thus effectively protecting the steel test piece. Therefore, Gly-PESA was a green scale and corrosion inhibitor, which solved the problem of environmental pollution.

Kinetics and scale inhibition application studies towards bulk and RAFT copolymerization of maleic anhydride and acrylic acid

Poly(maleic anhydride) (PMA) is commonly reckoned as a better water scale inhibitor than poly(acrylic acid) (PAA) since each maleic anhydride unit can supply two carboxylic acid groups. However, pure PMA is difficult to achieve because the steric effect of its monomer MA. Herein, we synthesize copoly(MA-AA) copolymer by bulk polymerization method (bulk-copoly(MA-AA)), which avoids the use of any solvents which have to be removed afterwards. In addition, we also synthesize copoly(MA-AA) by reversible addition-fragmentation chain transfer (RAFT) polymerization method to afford RAFT-copoly(MA-AA) with low polydispersity index (PDI) less than 1.2, and the performance of RAFT-copoly(MA-AA) in water scale inhibition is more excellent relative to bulk-copoly(MA-AA). We also synthesize other copoly(MA-AA) copolymers by varying the molar ratio of MA to AA to study the polymerization mechanism. Through the static scale inhibition experiment, it is concluded that when the concentration of copoly(MA-AA) is 80 mg/L, the scale inhibition performance of RAFT-copoly(MA-AA) can reach 96.50 % which is the best among the control samples. It is also found that only 1:1 alternating copolymerization of MA and AA could be achieved as demonstrated by 1H nuclear magnetic resonance spectra of the copolymers, evidencing the strong steric hindrance of MA for its homo-polymerization.

Phosphonated Polyetheramine-Coated Superparamagnetic Iron Oxide Nanoparticles: Study on the Harsh Scale Inhibition Performance of Calcium Carbonate and Barium Sulfate.

Harsh scale buildup, such as calcium carbonate (calcite) and barium sulfate (barite), poses significant challenges in the oil and gas industry. While various scale inhibitors (SIs) are employed to mitigate this issue, there is a need for greener, more efficient, compatible, and affordable alternatives. Calcium compatibility often complicates the use of SIs, potentially leading to formation damage. Our group has recently synthesized a recyclable nanocomposite scale inhibitor made of superparamagnetic nanoparticles coated with a trisodium citrate linker to phosphonated poly(ether amine) (SPION-TSC-PPEA) and tested it against calcium sulfate (gypsum), a simple form of scale buildup. This study evaluates the recyclable nanocomposite scale inhibitor's efficiency in mitigating calcite and Barite scales through static jar tests and high-pressure dynamic tube-blocking tests at 80 bar and 100 °C. The nanocomposite demonstrated high calcium ion compatibility, excellent inhibition efficiency against calcite, moderate efficiency against Barite, and maintained efficacy over five recycling cycles.

Preparation of a novel hyperbranched polymer and its scale inhibition performance

Preparation of a novel hyperbranched polymer and its scale inhibition performance

Synthesis and Mechanism of a Green Scale and Corrosion Inhibitor.

A new green water treatment agent, a poly(aspartic acid)-modified polymer (PASP/5-AVA), was synthesized using polysuccinimide and 5-aminovaleric acid (5-AVA) in a hybrid system. The structure was characterized, and the scale and corrosion inhibition performance were carried out with standard static scale inhibition and electrochemical methods, respectively. The mechanism was explored using XRD, XPS, SEM, and quantum chemistry calculations. The results indicated that PASP/5-AVA exhibited better scale and corrosion inhibition performance than PASP and maintained efficacy and thermal stability of the scale inhibition effect for a long time. Mechanistic studies indicated that PASP/5-AVA interferes with the normal generation of CaCO3 and CaSO4 scales through lattice distortion and dispersion, respectively; the combined effect of an alkaline environment and terminal electron-withdrawing -COOH groups can induce the stable C- ionic state formation in -CH2- of the extended side chain, thus enhancing its chelating ability for Ca2+ ions. At the same time, the extension of the side chain length also enhances the adsorption ability of the agent on the metal surface, forming a thick film and delaying the corrosion of the metal surface. This study provides the necessary theoretical reference for the design of green scale and corrosion agents.

Performance Assessment of Biomass-derived Urea-Furfuraldehyde Resins as Oilfield Scale Inhibitors

Oilfield-scale formation is a persistent challenge in the oil industry. While numerous scale inhibitors have been in use for decades, there is a significant research gap in discovering renewable, cost-effective, ecologically friendly, and efficient inhibitors. This study sets out to fill this gap by investigating the potential of scale inhibitors (SIs) made from bio-resin derivatives of red onion skin; ROF and ROFU, in reducing CaCO3 and CaSO4 scales. The scale inhibition performance of ROF and ROFU was rigorously evaluated using the NACE standard static bottle test method. The data revealed that increasing scale-inhibitor contact time, concentration, and temperature enhances inhibitor efficacy, with the best inhibition efficiencies found for ROF and ROFU on the CaSO4 scale compared to the CaCO3 scale across all studied parameters. A comparison of the prepared SIs with a commercial scale inhibitor (CSI) showed a high inhibition rate of over 90% at minimal dosage of 60ppm in both scales studied. Despite having a lower inhibition rate (IE) than CSI, ROF and ROFU demonstrate significant potential as green oilfield SIs. This sustainable technique, which transforms agro-waste into a valuable oilfield chemical via a one-pot chemical process, could have profound economic and societal benefits, offering hope for a more sustainable future in the oil industry.

Scale inhibition mechanism of itaconic acid-sodium methacrylate sulfonate on calcite: Quantum chemical calculation and molecular dynamics simulation

In order to explore the scale inhibition mechanism of green scale inhibitor-itaconic acid-sodium methacrylate sulfonate (IA-SMAS) on calcium carbonate (CaCO3), the scale inhibition characteristics of IA-SMAS were studied by quantum chemical calculation and molecular dynamics simulation. The charge distribution, electrostatic potential distribution, geometric matching degree and frontier molecular orbital energy of IA-SMAS were analyzed by quantum chemical calculation. It was found that IA-SMAS molecules have the ability to bind to Ca2+ at the micro level, occupy the growth active sites of crystal during the growth of calcite crystal planes, and inhibit the normal growth of crystal. Based on the molecular dynamics simulation method, the effects of IA-SMAS concentration on the adsorption configuration, radial distribution function and interaction energy in the binding process of IA-SMAS with calcite crystal planes were analyzed. The results show that the area of calcite crystal planes covered by IA-SMAS molecules, the peak value of radial distribution function and the binding energy increase with the increase of IA-SMAS concentration. However, the relative concentration of water molecules near the calcite crystal planes decreases, and the trend of water molecules moves away from the crystal planes of calcite. It indicates that the high concentration of IA-SMAS molecules can occupy the position of water molecules, and enhance the scale inhibition efficiency. Therefore, the scale inhibition performance of IA-SAMS increases with the increase of its concentration in a certain range, and an appropriate increase in IA-SMAS concentration can effectively inhibit the growth of scale.

Nano-silica modified with silane and fluorinated chemicals to prepare a superhydrophobic coating for enhancing self-cleaning performance.

Superhydrophobic coatings with excellent self-cleaning performance have attracted significant concerns from researchers. Although various superhydrophobic coatings with prominent superhydrophobic properties have been fabricated, most developed coatings are still inadequate in pipeline scale inhibition applications. In this work, nano-silica (nano-SiO2) was modified by silane coupling of vinyltriethoxysilane (VETS) and 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane (PFTS) to prepare a superhydrophobic coating. Organosilicon of PFTS and VETS was grafted onto the surface of SiO2 for preparing the superhydrophobic coating with low surface energy, and the superhydrophobic coating was cured via poly(vinylidene fluoride) (PVDF). The results showed that the contact angle of the prepared silica-based superhydrophobic coating, denoted as VETS-PFTS@SiO2/PVDF, is 159.2°, exhibiting outstanding superhydrophobicity performance. Furthermore, the superhydrophobicity coating also showed satisfactory durability performance in 200 g load wear test after 50 cycles. Importantly, the superhydrophobic coating displayed promising mechanical durability, chemical stability performance, as well as maintained excellent superhydrophobic properties after being placed in water for 3 weeks, indicating the potential for long-term utilization. In the simulated scale inhibition test, it was found that the synthesized coating can also significantly decrease the deposition rate of CaCO3 and successfully enhance its scale inhibition performance.

Sustainable Calcite Scale Inhibitors via Oxidation of Lignosulfonates.

Deposition of inorganic scales in wells, flow lines, and equipment is a major problem in the water treatment, geothermal, or upstream oil and gas industries. Deployment of scale inhibitors has been adopted worldwide for oilfield scale prevention. Commercial synthetic scale inhibitors such as polymeric carboxylates and sulfonates or nonpolymeric phosphonates offer good scale inhibition performance but often suffer from one or more limitations including biodegradability, calcium compatibility, and thermal stability. Lignin-based biomaterials such as sodium lignosulfonates are natural, sustainable, and widely available polymers that are accepted for use in environmentally sensitive areas. Here we show that, although lignosulfonates perform relatively poorly as calcite scale inhibitors in dynamic tube blocking tests, oxidized lignosulfonates show a much improved inhibition effect by a factor of 20-fold. The oxidized lignosulfonates are easy to prepare in a 1-step reaction and show excellent calcium compatibility and thermal stability, useful for downhole squeeze treatments in high temperature wells. This present study unequivocally establishes oxidized lignosulfonates as a new class of sustainable green scale inhibitors, thereby bridging the gap between materials derived directly from nature and the classic synthetic polymeric scale inhibitors.

Synthesis, scale and corrosion inhibition evaluation and mechanism of 2-aminobenzimidazole modified polyaspartic acid

With the growing public concern for environmental preservation, this work employs environmentally friendly polyaspartic acid (PASP) as the main chain, to develop a green and efficient dual-function inhibitor with scale and corrosion inhibition. The new inhibitor PASP-2-A was synthesized by grafting 2-amino-benzimidazole (2-A) containing nitrogen heterocyclic into polysuccinimide under alkaline conditions. The corrosion inhibition of carbon steel and brass was determined by static test, polarization curve and electrochemical impedance spectroscopy (EIS). It can be found that PASP-2-A had better scale inhibition performance than PASP under different conditions. The addition of 5 mg·L−1 PASP-2-A can almost 100% prevent the formation of CaCO3 scale. Molecular dynamics simulation results showed that PASP-2-A significantly destroys the crystal structure of CaCO3 scale due to the coordination between PASP-2-A and Ca2+ groups. The modified PASP scale inhibitor can prevent the growth of calcite (110) and (104) crystal faces, regulate the transformation of CaCO3 from stable calcite to more soluble spherical vaterite, making it less deposit. The electrochemical test results showed that the corrosion inhibition of PASP-2-A is greatly improved compared with PASP, and the corrosion inhibition of Q235 carbon steel increased about 40% at the dosage of 200 ppm. The corrosion inhibition efficiency of H62 brass in 3.5 wt% NaCl was 97.97% with 300 ppm PASP-2-A. Notably, due to its degradable nature, low toxicity, and affordability, PASP-2-A serves as an excellent inhibitor, exhibiting remarkable performance in both scale inhibition and corrosion inhibition. Consequently, it presents a promising avenue for further advancements in modified PASP.

Investigation of scaling inhibition and biofouling potential of different molecular weight fractions of a PAA antiscalant

This study investigates the scale inhibition performance of a commercial polyacrylic acid-based (PAA) antiscalant used for drinking water production and its molecular weight fractions (≤ 500 Da, ≥ 500 Da). The investigated antiscalant is used to prevent sulfate and carbonate scaling in treatment of drinking water sources by reverse osmosis or nanofiltration (RO/NF). Based on two complementary tests involving determination of induction time in a batch test and rate of flux decline in a lab-scale RO/NF plant, concordant results were obtained, proving that the overall performance of commercial PAA was controlled almost entirely by the higher molecular weight fraction. The low molecular weight fraction, which is potentially more permeable through the NF/RO membrane, showed poor inhibition against both sulfate and carbonate scalants. Furthermore, measurements on the assimilable organic carbon (AOC) by flow cytometry reveals that the low molecular weight PAA fraction has low biological stability, as its potential transport into the permeate of a NF270 nanofiltration membrane was inferred by elevated AOC values in the NF-permeate. These results are crucial information for water utilities, plant engineering, regulatory bodies and public authorities with respect to the possible operation of RO/NF especially in drinking water production.

Synthesis and evaluation of a new scale inhibitor: the modified epoxysuccinic acid copolymer

Polyepoxysuccinic acid (PESA) scale inhibitor is widely recognized as a green and environmentally friendly scale inhibitor. However, its functional group type is single and cannot be used for a variety of scales. Based on this, a modified epoxy succinic acid quaternary polymer scale inhibitor PEAPS was prepared by introducing a variety of functional groups. The effects of scale inhibitor dosage, temperature, and solution pH on the scale inhibition performance of CaCO3, CaSO4, BaSO4, and SrSO4 were studied. At the same time, it is compared with the commonly used oilfield scale inhibitors Polyacrylic acid (PAA), PESA, and Ethylenediaminetetramethylenephosphonic acid (EDTMP). The results show that under the optimal synthesis conditions, the scale inhibition efficiency of PEAPS scale inhibitor on CaCO3 scale and CaSO4 reaches 100%, and the scale inhibition efficiency of BaSO4 and SrSO4 can reach at least 60%. Its comprehensive scale inhibition efficiency is better than other commonly used scale inhibitors under the same test conditions, and it has certain corrosion inhibition performance through static corrosion evaluation. The crystal parameters and micro-morphology of the four scales before and after the addition of scale inhibitor were analyzed using SEM and XRD. The results showed that after adding the PEAPS scale inhibitor, the crystal structure parameters of the CaCO3 scale and CaSO4 scale changed, and the micro-morphology of the four scale crystals also changed, to achieve the purpose of scale inhibition.

Preparation and scale inhibition performance of modified polyaspartic acid (M-PASP)

Modified polyaspartic acid (M-PASP) was synthesized by modifying ammonia- polysuccinimide (ammonia-PSI) through a ring-opening reaction using a modifier derived from ethylenediamine, maleic anhydride, and NaOH. In addition to M-PASP, conventional polyaspartic acid (PASP) was also synthesized for comparison. The structure of conventional PASP and M-PASP were characterized by FT-IR and 1H NMR. The influence of raw materials ratio, reaction temperature and reaction time on the intrinsic viscosity of M-PASP were investigated in detail. The static scale inhibition method was used to evaluate the scale inhibition performance. The results showed that M-PASP exhibited significantly superior scale inhibition performance against CaCO3 compared to conventional PASP. Additionally, it was observed that the scale inhibition rate of M-PASP on CaCO3 increased with increasing intrinsic viscosity. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were employed to examine the surface morphology and structure of CaCO3 crystals, respectively. The results revealed that the addition of M-PASP led to a reduction in the grain size of CaCO3 crystals and disruption of their surface morphology. In addition, molecular dynamics (MD) simulation was utilized to analyze the interaction mechanism between the polymers and calcium carbonate crystals. Based on the findings, it was postulated that the scale inhibition mechanism of M-PASP against CaCO3 involves a comprehensive interplay of several factors, including chelation solubilization, dispersion aggregation and lattice distortion.

Experimental study on scale inhibition performance and fouling characteristics of spiral insert in heat transfer tube

In order to study the anti-scaling and descaling performance in the process of cooling crystallization, the effects of flow velocity and reciprocating displacement on fouling resistance and overall heat transfer coefficient under two spiral insert schemes are experimentally studied. The system studied in the experiment is a saturated sodium sulfate solution, which forms crystalline fouling during the experiment. The micro structure of the fouling layer is investigated to explain the variation of macroscopic thermal parameters. The average fouling thickness curve is obtained by heat transfer theory analysis. The results show that the maximum decrease of the asymptotic value of the fouling resistance of the fixed spiral insert is 63 % with the increase of the flow velocity. When the reciprocating displacement of the spiral insert increases to one pitch, the asymptotic value of the fouling resistance decreases by 83 %, and the overall heat transfer coefficient decreases by only 3 %. The particle size and porosity of fouling at different observation positions gradually increased, while the shape of fouling crystals changed from small to regular, and the degree of bonding changed from tight to loose. Statistics on the particle size of fouling particles show that the fouling particle size increases from 2-8 μm to more than 30 μm. For the fixed spiral inserts, the porosity of the fouling layer is up to 42 %, but the porosity of the middle layer increases rapidly with the flow velocity. With the change of flow velocity, the flow field characteristics in the tube are the main reason for changing the structure of the fouling layer. With the increase of reciprocating displacement, the collision effect of the spiral on the fouling layer is more comprehensive, and the interlayer bonding of the fouling layer is completely destroyed. In the field of industrial cooling crystallization, it can greatly improve the heat transfer efficiency of the inner wall crystallization process.

Study on the scale inhibition performance of organic chelating agent aided by surfactants on CaCO3 at high salinity condition

Abstract The salt blockage layer formed in the wellbore during the development of high salinity oil and gas fields has a serious impact on the safety of oil and gas production of the oil and gas fields. CaCO3 is the main component of scale in high salinity oil and gas fields. Herein, focusing on CaCO3 as an example, the precipitation and scaling process as well as the change of crystalline form of CaCO3 under different temperature and salinity conditions were studied. The effects of two addition methods of organic chelating agent on the solubilization and dislodgement of CaCO3 under high salinity conditions were also explored. The optimal concentration of organic chelating agent is determined to be 1 % and 5 % for solubilization and dislodgement, respectively. It was found that the solubilization is achieved by inhibiting the stable and difficult to treat calcite crystal phase to generate more irregular and more dispersed aragonite CaCO3. Organic chelating agent contains a large number of carboxyl groups in its molecules, which can be adsorbed onto the surface of CaCO3 crystals through electrostatic adsorption. By chelating Ca2+ in stable and difficult to treat calcite CaCO3, the further ordered growth of the crystals is prevented, causing lattice distortion or large crystal rupture, thereby achieving dislodgement. This study will provide theoretical and technical support for the solubilization and dislodgement of salt blockage layer in wellbore at high salinity conditions.

Study on synthesis and properties of environmental protection water treatment agent

The copolymers were obtained by a water-based polymerization reaction using maleic anhydride and acrylic acid as the main raw materials. And the scale inhibition performance of the resulting scale inhibitor was investigated by static scale inhibition experiments. The experimental results proved that the scale inhibitor has good scale inhibition performance for calcium carbonate and calcium sulfate. When the dosage is 100mg/L, the scale inhibition rate of the agent reaches 100%. This avoids the hidden danger of affecting normal production due to system scaling.

Preparation of carboxy sulfonic acid‐containing copolymer scale inhibitors and their scale inhibition effect on CaCO3

AbstractFree radical polymerization was selected to obtain a promising copolymer scale inhibitor IA‐AM‐SAS with good water solubility and temperature and salt resistance, which is suitable for the treatment of surface pipeline water in oil fields, using itaconic acid (IA), acrylamide (AM), and sodium acrylsulfonate (SAS) as the monomers. The structure of the synthesized copolymer was verified by Fourier transform infrared spectroscopy and nuclear magnetic resonance hydrogen spectroscopy. Thermogravimetric results showed that the copolymer does not undergo significant thermal degradation at temperatures below 356°C, indicating that the copolymer has good thermal stability. The molecular weights of the polymers at different monomer ratios were measured using gel permeation chromatography and the relationship between the molecular weights and scale inhibition performance was discussed. The results showed that the scale inhibition effect was best when the monomer molar ratio n(IA): n(AM): n(SAS) was 0.5:2:1.5 and the number of average molecular weight of the prepared copolymer was 7712 g/mol, and the inhibition efficiency of CaCO3 was 84.02% when IA‐AM‐SAS was at a concentration of 30 mg L−1, and the inhibition rate was measured by the standard of static scale inhibition test in the oilfield measured. The range of conditions (PH, Ca2+ concentration, water temperature, and time) of the static scale inhibition test was then expanded using a one‐way controlled variable experiment to explore the performance of IA‐AM‐SAS scale inhibitors under different water quality conditions. The scale inhibition mechanism was explored by scanning electron microscopy, x‐ray diffraction, and x‐ray photoelectron spectroscopy. Briefly, the combination of multiple functional groups enables IA‐AM‐SAS to be applied in complex and challenging environments.

Analysis of the process of resource utilization of AMPS kettle residues

As a widely used synthetic raw material in industrial production, a large amount of 2-Acrylamido-2-methylpropanesulfonic acid (AMPS) is produced every year. However, many wastes will be generated from the kettle residues of AMPS production. If these wastes are not properly disposed of in a timely manner, they can result in environmental pollution, pose environmental hazards, and lead to economic losses. In this paper, a new process technology is proposed in which the waste from the AMPS reactor residue can be combined with acrylic acid (AA) to create a new polymer.This polymer has a structure similar to the industrial scale inhibitor TH3100 as shown by the NMR, FTIR and TG analysis. Scale inhibition experiments are conducted on CaCO3, Ca3(PO4)2 and CaSO4 to demonstrate the polymer's excellent scale inhibition performance. Besides, the polymer shows a low biological toxicity as proved by zebrafish toxicity tests. Thus, the proposed novel process technology not only manages the waste in the AMPS kettle, but also resources it as an alternative to industrial-scale inhibitors, producing economic benefits as well as protecting the environment.

A novel method for scale inhibition by the synergistic action of triboelectric nanogenerator and copper-based alloy

In order to improve the scale inhibition of copper-based alloys, a novel method is proposed by the synergistic action of triboelectric nanogenerator and copper-based alloy. A triboelectric nanogenerator (TENG) based on copper-based alloy material embedded in polytetrafluoroethylene (PTFE) was constructed, and a scale inhibition structure of coupling the (solid-liquid) triboelectric nanogenerator and the copper-based alloy was designed. Additionally, the alloy scale inhibition device was constructed by utilizing alloys as the scale inhibition element, and the synergistic scale inhibition device was developed by utilizing a coupled structure. Power generation performance tests were conducted for both scale inhibition elements, and scale inhibition effectiveness tests were conducted for both synergistic scale inhibition devices. Measurement results show that the power generation performance of the synergistic scale inhibition element is significantly higher than that of the alloy scale inhibition element. This indicates that the addition of solid-liquid TENG can greatly increase the surface potential of the alloy scale inhibition element. The enhancement of the scale inhibition performance of the alloy scale inhibition element by solid-liquid TENG is primarily due to this principle. The scale inhibition performance experiment measurement results show that the synergistic scale inhibition effect of solid-liquid triboelectric nanogenerator and copper-based alloy can be realized. The remaining calcium ion concentration in the water treated by the coupling structure is higher than that in the water treated by the copper-based alloy. The scale inhibition rate of copper-based alloy embedded in the solid-liquid triboelectric nanogenerator is significantly increased. Therefore, the scale inhibition performance of copper-based alloy embedded in triboelectric nanogenerators can be improved significantly.
