Polyacrylamide-based Polymers for Enhanced Oil Recovery
Today, partially hydrolysed polyacrylamide (HPAM) polymers are the most commonly used type of polymer. The conversion of some of the amide groups on the polyacrylamide to carboxylate groups provides greater viscosity, even when low concentrations of polymer are added to the injected water 4 .
We offers 863 hpam polymer products. About 2% of these are Water Treatment Chemicals, 6% are Electronics Chemicals, and 7% are Paper Chemicals. A wide variety of hpam polymer options are available to you, such as usage.

The effect of polyacrylamide on corrosion behavior of N80 steel in the HPAM/H 2 S/CO 2 environment was studied by using weight‐loss and electrochemical tests to simulate the environment of production wells in polymer flooding. The morphology and composition of corrosion scales were studied by scanning electron microscopy, energy dispersive X‐ray spectrometer, and X‐ray photoelectron

Partially hydrolyzed polyacrylamide (HPAM) as the main component of slickwater fracturing fluid is a shear-sensitive polymer, which suffers from mechanical degradation at turbulent flow rates. Five different concentrations of HPAM as well as mixtures of polyacrylamide/xanthan gum were prepared to investigate the possibility of improving shear stability of HPAM.

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.

PHPA (also partially hydrolyzed polyacrylamide or HPAM) is designed for easy mixing in drilling mud systems and to improve its dispersion to eliminate “fish eyes”, This occurs in field work when mixing either large quantities rapidly or mixing high polymer concentrations without good mixing equipment.In drilling fluids, PHPA is an anionic polyacrylamide and it can act as a viscosifier
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- What is polyaluminium chloride production?
- PolyAluminium Chloride production is one of the most exigent process for glass-lined equipement due to its high corrosive and abrasive effect. That's why, the experience and the qualification of De Dietrich Process Systems allow to meet qualitatively those process requirements.
