Inhibition and dispersion of polyepoxysuccinate as a scale inhibitor

Journal of Environmental Sciences, 2011
The inhibition and dispersion of polyepoxysuccinate (PESA, self-manufactured) to inorganic scale was evaluated by scale static beaker test to CaC03 and Ca3(P04)2, stability test to zinc salt, and dispersion test to ferric oxide. The experimental results demonstrated that PESA functioned excellent scale inhibition to CaC03 and Ca3(P04)2, good stability ...

Searching for a universal scale inhibitor: A multi-scale approach towards inhibitor efficiency

Geothermics, 2021
Abstract Scale inhibition is of crucial importance in harvesting geothermal energy, an attractive, renewable and sustainable energy source. The majority of the geothermal reservoir waters around the world contain a variety of anions and cations, which are prone to precipitation when subjected to vast transformations of both temperature and pressure ...

Testing cancer inhibitors at scale

Nature Biomedical Engineering, 2018
A scalable and fast method for profiling single-molecule protein–protein interactions predicts the sensitivity of cells to inhibitors of the epidermal growth factor receptor, which is typically overexpressed in cancer.

A Way Beyond Scale Inhibitors – Extending Scale Inhibitor Squeeze Life through Bridging

International Symposium on Oilfield Scale, 2003
Abstract The Heidrun Field is located in the Haltenbanken area offshore Mid-Norway. The reservoir temperature is 85 – 88 °C and the reservoir pressure is close to hydrostatic pressure, around 250 bar. Seawater injection is utilized to increase recovery and for pressure support.

Metal Sulfide Scale Inhibitors

CORROSION 2020, 2020
Abstract Metal sulfide mineral scaling, fouling and deposition are frequently encountered problems in geothermal systems. Their formation, crystallization and deposition occur principally because of their extremely low solubility, based on the low solubility product (Ksp).

New Developments on the Analysis of Scale Inhibitors

SPE International Conference on Oilfield Scale, 2010
Abstract Scale inhibitors (SI) are used to control oilfield scale formation and the ability to analyse these species is very important such that SI concentrations as low as 0.5ppm active need to be measured accurately. If phosphorus is present in the SI molecule, then ICP based methods may be used for analysis.

An Evaluation of Scale Inhibitors

Journal of Petroleum Technology, 1972
A rating of inhibitors in the order of their effectiveness is a relative matter and depends upon test conditions. The most important conditions are the degree of supersaturation and the temperature; the higher the supersaturation and the higher the temperature the less effective a scale inhibitor becomes.

Inhibition of Barite Scale in the Presence Of Hydrate Inhibitors

SPE International Symposium on Oilfield Scale, 2004
Abstract Large volumes of hydrate inhibitors (e.g., methanol, ethanol, monoethylene glycol, and triethylene glycol as cosolvent) are added to control hydrate formation. Such practice has an adverse effect on scale formation since the mineral salts are generally less soluble in the cosolvent.

Can Green Scale Inhibitors Replace Phosphonate Scale Inhibitors?: Carbonate Coreflooding Experiments

Petroleum Science and Technology, 2009
Abstract The oil industry is currently facing severe restrictions concerning the discharge of oilfield chemicals into the environment. The purpose of this study is to test the possibility of replacing an organic phosphonate scale inhibitor (DETPMP) by a more environmentally friendly “green” species: carboxymethyl inulin (CMI). Although, promising these
