“…The degradation of phosphonates were previously studied by Nowack and Stone (2000) and Dyer et al (2004). Nowack and Stone (2000) studied the degradation of DTPMP and NTMP in the presence of Mn and molecular oxygen and found that the degradation rate of DTPMP is substanticially slower than that of NTMP at room temperature.…”

“…PVS was the most thermally stable among the tested inhibitors, and its thermal stability was not affected by solution pH (Dyer and Graham 2003). Their study also suggested that the inhibitor testing with respect to barite scale is more sensitive than that with respect to calcite, with regard to the reduction of inhibition efficiency as a result of inhibitor thermal degradation (Dyer et al 2004).…”

“…Their work indicated that manganese can greatly catalyze the thermal autoxidation of phosphonates (Nowack and Stone 2000). In recent studies on inhibitor thermal stability (Dyer and Graham 2003;Dyer et al 2004;Kotlar et al 2006;Wat et al 2008;Wang and Wylde 2009;Wilson and Harris 2010;Fan et al 2012), scale inhibitors were preheated and then tested for calcite or barite inhibition by way of dynamic-loop or static-bottle tests. Dyer and Graham studied the thermal stability of three generic barium sulfate scale inhibitors-polyvinyl sulfonate (PVS), phosphinopolycarboxylic acid (PPCA), and diethylenetriamine penta(methylene phosphonic acid) (DTPMP)-under both static and dynamic conditions.…”

A Novel and Comprehensive Study of Polymeric and Traditional Phosphonate Inhibitors for High-Temperature Scale Control

A novel barite-inhibition assay based on the nucleation and inhibition model has been proposed and used to evaluate the thermal stability of phosphonates and polymeric scale inhibitors with regard to their potential application in high-temperature wells. Systematic experiments have been conducted to investigate the time (minutes to days) and temperature (up to 200 C) dependence of inhibitor thermal degradation, the impact of stainless steel and iron on the degradation of inhibitors at high temperatures, and the difference between aging tests with inhibitors in solution and with those inhibitors adsorbed on core materials. The results not only enable a more accurate understanding of the thermal degradation of scale inhibitors but also facilitate the selection and placement of scale inhibitors for high-temperature oil and gas production.

“…Phosphonate groups were inserted into 2-aminobenzimidazole to develop such inhibitor with an improved corrosion inhibition as well as a high scaling inhibition efficiency. In fact, phosphonate is known as an anti-scaling group [30][31][32]. This threshold inhibitor is added to aquatic media even with high calcium ion concentration and disrupts the formation of precipitates by means of adsorption onto crystal growth sites [33].…”

Synthesis, characterization and electrochemical performance of a new imidazoline derivative as an environmentally friendly corrosion and scale inhibitor

et al. 2015

A new imidazoline derivative, {[(benzimidazol-2-ylmethyl)imino] bis(methylene)} bis(phosphonicacid), named as BMIBMBPA, was synthesized as an environmentally friendly corrosion and scale inhibitor. The performance of BMIBMBPA for carbon steel in cooling tower water was evaluated using weight loss, electrochemical measurements and a scale test and compared to that of sodium tungstate. The optimum concentration of BMIBMBPA was measured to be 40 mg/L and a much higher value, even at lower inhibition efficiencies, was determined for sodium tungstate. The electrochemical measurements demonstrated that BMIBMBPA acts as a mixed-type corrosion inhibitor. Surface analyses revealed adsorption of BMIBMBPA and scale inhibition through disruption in growth of precipitates.
