PHASE BEHAVIOUR OF PHOSPHINOPOLYACRYLATE SCALES INHIBITOR
Journal of Dispersion Science and Technology, 1999Abstract The influence of the Ca++ and inhibitor concentrations, pH, and temperature on the phase behaviour and precipitation yield of a phosphinopolyacrylate scale inhibitor, PPAA, has been studied. The results are interpreted in terms of the chemical processes governing PPAA-Ca++ complexation, and evidence for the role of inhibitor molecular weight ...

Technical Aminopolymethylenephosphonic Acids as Scale Inhibitors
Phosphorus and Sulfur and the Related Elements, 1987Abstract Aminopolymethylenephosphonic acids are complexing agents which can easily be synthesized technically and which, referring to their strong threshold effect, are used to a large extent as scale inhibitors. As a consequence of their increasing use, especially in the oil industry, they now represent the largest group of commercially available ...

Sodium chloride (halite) has been traditionally regarded as an unconventional oilfield mineral scale, compared with more prevalent carbonate and sulfate scales. However, with the increasing productions from offshore deepwater and shale gas fields, halite

Scale inhibitor for boiler water systems
Russian Journal of Applied Chemistry, 2014Hardness deposition in boiler systems is an inevitable and progressive process. Often good treatment of feed water and control of condensate chemical composition cannot prevent entirely hardness scale. Scaling in boilers results in failure of heat exchange, temperature rise of pipe walls causing higher power costs and safety loss of this type of ...

Bioinspired “Green” Scale Inhibitors for Mitigation of Silica Scales.
2017Abstract. Marine biological systems annually process 6.7 gigatons of “Si”. Diatoms and other marine organisms stabilize high concentrations of “soluble silica” (~ 19-340 mM, depending on the diatom species) prior to biosilica formation.

Synergistic Scale Inhibitor Blends for Severe Carbonate Scaling Systems
All DaysAbstract Control of inorganic sulphate and carbonate scales with polymer and phosphonate based scale inhibitors is well established within the oilfield chemical industry. The potential for synergistic interactions with blends of these chemical types to give reduced treatment rates, lower chemical discharge volumes and potentially lower ...

Bioinspired “Green” Scale Inhibitors for Mitigation of Silica Scales
CORROSION 2016, 2016Abstract Marine biological systems annually process 6.7 gigatons of “Si”. Diatoms and other marine organisms stabilize high concentrations of “soluble silica” (~ 19-340 mM, depending on the diatom species) prior to biosilica formation. It is believed that Nature can achieve that by the intervention of, unknown as of yet, biopolymers that
