What is Partially Hydrolyzed Polyacrylamide (PHPA
Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability.

Rheological Properties of Partially Hydrolyzed
This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aqueous HPAM-based SiO2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times. The results show that the inclusion
We hereby employ molecular dynamics (MD) simulations (∼6 μs in total) to investigate the chain dynamics, aggregation, and interfacial properties of the partially hydrolyzed polyacrylamide (HPAM) polymer. HPAM is widely used in chemical enhanced oil recovery (cEOR) applications. The conformational changes and aggregation properties are examined in different conditions simulating cEOR activities.
PHPA (Partially Hydrolyzed Polyacrylamide) Manufacturer
Partially Hydrolyzed Polyacrylamide (HPAM) in act with water after polymer flooding in oil filed reasons in environmental troubles, such as enhancement in the oil-water detachment trouble, natural degradation to make toxic acrylamide and jeopardize local ecosystem. Bio-degradation of HPAM may be a cost-efficient mode for solving these problems.
For EOR, partially hydrolyzed polyacrylamide (HPAM) solution with 0.5 wt.% NaOH showed a better sweep efficiency than polymer flood . In wastewater treatment, a low cationic polyacrylamide (4 mg/L PAM) to high rate algal pond (HRAP) treating wastewater in New Zealand achieved at least 50% improvement of total suspended solid (TSS) removal [ 39 ].

polyacrylamide has gained significant interest due to its application in enhanced oil recovery (EOR). In this process, static mixers are used to mix partially hydrolyzed polyacrylamide (HPAM) with injected water to recover the oil from reservoir. Since this polymer solution is extremely viscous, static mixers are used to perform this operation.
Polymer Injectivity: Investigation of Mechanical
Hence, determining polymer in-situ rheological behavior is of great significance for defining its utility. In this study, an investigation of rheological properties and mechanical degradation of different partially hydrolyzed polyacrylamide (HPAM) polymers was performed using Bentheimer sandstone outcrop cores.
Currently, most profile control agents would be degraded in strong alkaline condition. They could not be applied in ASP (alkaline, surfactant and partially hydrolyzed polyacrylamide) flooding. To solve this problem, a new kind of alkali-resistant gel for deep profile has been studied.
- Who manages water supply and wastewater treatment in Russia?
- Water supply and wastewater treatment in Russia is managed by "Vodokanals". The progressive decentralisation process of water set out to bring the decision-making process closer to local conditions.
- How can private sector technology improve water supply in Russia?
- Water supply across Russia is in desperate need of modernisation. The St Petersburg project is one example that shows, once lengthy contract negotiation has been passed, private sector technology and solutions can make a difference. A saving of €65,000 is notable for any utility.
- How is water treated before use?
- Water supplied to domestic properties such as for tap water or other uses, may be further treated before use, often using an in-line treatment process. Such treatments can include water softening or ion exchange. [citation needed]
- What is treatment for drinking water production?
- Treatment for drinking water production involves the removal of contaminants and/or inactivation of any potentially harmful microbes from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect.
