“…Chemical dosing is one of the most traditional and effective methods for the treatment of circulating cooling water. − However, water eutrophication caused by the discharge of wastewater containing phosphorus and nitrogen has increased the strictness of wastewater discharge restrictions. − To protect water resources and meet sustainable development requirements, higher demands have been put forward to produce more green water treatment agents. As such, the development of environmentally friendly water treatment agents and technologies has become the focus of many scientific studies at both home and abroad.…”

A novel phosphorus-free and non-nitrogen scale inhibition and dispersion agent was synthesized from epoxysuccinic acid (ESA), itaconic acid (IA), and sodium methyl propylene sulfonate (SMAS). It was characterized by infrared spectroscopy (IR), nuclear magnetic resonance (NMR), and elemental analysis, and its molecular weight and distribution were determined by gel permeation chromatography (GPC). Static experimental methods were used to evaluate the scale inhibition against CaCO 3 , Ca 3 (PO 4 ) 2 , and CaSO 4 . The dispersion ability was evaluated by measuring the dispersive property of iron oxide. By observing the morphology of the CaCO 3 scale, the scale inhibition mechanism was discussed. The results showed that when the ratio of raw materials (ESA/IA/ SMAS) was 10:10:5, the scale inhibition rate of CaCO 3 and CaSO 4 reached 100% with the dosages of 20 and 10 mg/L, respectively. In addition, the scale inhibition rate against Ca 3 (PO 4 ) 2 was up to 96.64% with a dosage of 100 mg/L. The property of dispersing iron oxide exhibited the best results with 50 mg/L of the agent. On the 21st day, the biodegradation rate reached 63.33%. This polymer was an environmentally friendly antiscale and dispersant with good scale inhibition and biodegradability.

“…The most effective and famous additives are poly(acrylic acid), poly(methacrylic acid), and poly(Maleic acid) which are widely used as scale inhibitors in thermal plants [262][263][264] for reducing scale formation and increasing process performance. Another kind of polymeric additives for water desalination using membrane processes is polyamino polyether methylenephosphonate (PAPEMP), which is an ideal additive as it controls calcium carbonate and calcium sulfate scale formation and deposition [265,266]. Addition of this chemical could reduce or eliminate acid feed, therefore reducing hazardous risk and increasing water production.…”

Scale deposition is a critical issue in oil and gas exploration and production processes, causing significant blocking in tubing and consequently flow assurance and economic losses. Most studies addressing the scale formation have been limited on the experimental impact of different variables on scale formation. In this work, the inhibition of barite scale deposition was investigated by employing molecular simulations for three different scale inhibitors, namely, polyaspartic acid (PASP), nitrilotrimethylenephosphonate (NTMP), and dimethylenetriaminepenta(methylene-phosphonic acid) (DETPMP). Geometrical analyses were used to explore the performances of the inhibitors and visualize the outcomes. quantitative structure activity relationship parameters were also used to predict the activity of the inhibitors in the system. The order of the inhibitors is in agreement with the experiments with the following values for binding energies: −1.06, −0.17, and −2.33 eV for PASP, NTMP, and DETPMP, respectively. The results of this study indicated that the inhibition strength of the three inhibitors on barite scale formation can be sequenced as DETPMP > PASP > NTMP. Moreover, the ecological toxicity (eco-tox) properties were predicted, and the environmental impact of the different inhibitors was assessed. All inhibitors showed comparable eco-tox properties and predicted to be soluble in water. Molecular simulations proved to be an effective tool in the prediction of the performance and toxicity of barite scale inhibitors.
