Phosphonated IminodisuccinatesA Calcite Scale Inhibitor with Excellent Biodegradability [PDF]

open access: yesACS Omega, 2022
Scale inhibitors are an extremely important chemical in upstream oil and gas field operations and water treatment industries. These inhibitors prevent nucleation and/or crystal growth of scales such as calcite and barite. This keeps the pipes and other equipment and surfaces free from deposits, allowing the maximum flow of aqueous fluids. However, many

Efficiency of one scale inhibitor on calcium carbonate precipitation from hot water sanitary: effect of temperature and concentration [PDF]

open access: yesHeliyon, 2021
The scaling of hot water transport pipes has become one of the major problems encountered in Agadir's region, which exploits water of underground origin with very high hardness (40°F). Several methods can be used to prevent this phenomenon.

Linear-dendritic block copolymers as a green scale inhibitor for calcium carbonate in cooling water systems [PDF]

open access: yesDesigned Monomers and Polymers, 2017
Water-soluble monomer APEG-PG-(OH)n were produced and the Structure of APEG-PG-(OH)5 were identified by 1H-NMR. APEG-PG-(OH)n were copolymerized with maleic anhydride (MA) to synthesize no phosphate and nitrogen free calcium carbonate inhibitor MA/APEG ...

The study of a highly efficient and environment-friendly scale inhibitor for calcium carbonate scale in oil fields

open access: yesPetroleum, 2021
A highly efficient and environment-friendly scale inhibitor (MA-VA-VS) was synthesized via free radical solution polymerization method, where maleic anhydride (MA), vinyl acetate (VA) and vinyl sulfonate (VS) acted as monomers, while ammonium persulfate ...

A dynamic method for experimental assessment of scale inhibitor efficiency in oil recovery process by water flooding

open access: yesPetroleum, 2019
Scale formation due to the mixing of injection water with formation water causes formation damage and reduction in petroleum production. By using scale inhibitors, scale formation/scaling could be prevented.

Performance of a novel green scale inhibitor [PDF]

open access: yesE3S Web of Conferences, 2021
Many aspects of oilfield scale inhibition with green scale inhibi-tors (SIs) have remained untouched. For instance, the discharge of large amounts of produced water containing various types of hazardous chemi-cals, such as SIs into the environment has ...

Synthesis of Modified Polyaspartic Acid Scale Inhibitor and Its Scale Inhibition Performance [PDF]

open access: yesCailiao Baohu, 2023
In order to expand the application range of green scale inhibitor polyaspartic acid (PASP), a new green modified polyaspartic acid scale inhibitor (MPASP) was prepared using polysuccinimide (PSI) as the raw material and methionine (Met) as the ...

Synthesis and Scale Inhibition Performance of Serine - Modified Polyepoxysuccinic Acid Scale Inhibitor [PDF]

open access: yesCailiao Baohu, 2022
Polyepoxysuccinic acid (PESA) is a green and environmental scale inhibitor. Its application is limited due to its single functional group. In order to enhance its performance, an experiment was carried out by using serine (Ser) as the modifier to modify ...
