What is hydrolyzed polyacrylamide (HPAM)?

Sci. 2019, 136, 47793. ABSTRACT Partially hydrolyzed polyacrylamide (HPAM) is the water-soluble polymer most often used in flooding applications in the petroleum industry. However, in aqueous solutions at high temperatur…

Can cationic polyacrylamide be used for oily wastewater treatment?

Zhao C, Zheng H, Gao B, Liu Y, Zhai J, Zhang S, Xu B (2018) Ultrasound-initiated synthesis of cationic polyacrylamide for oily wastewater treatment: Enhanced interaction between the flocculant and contaminants.

Are polyacrylamides water soluble?

Discover the latest articles, news and stories from top researchers in related subjects. Polyacrylamides (PAM) are an important class of water-soluble polymers with low synthetic cost, high viscosity, and good rheological properties.

What is polyacrylamide used for?

Polyacrylamides (PAM) are an important class of water-soluble polymers with low synthetic cost, high viscosity, and good rheological properties. PAM is widely used for oil and gas extraction and wastewater treatment industries, especially in drilling fluids, fracturing fluids, polymer drives and other oil and gas extraction fields.

What are flocculants made of?

In most cases, flocculants are polymers composed of polyacrylamide (PAM) (Taylor et al. 2002). PAM is a polymer with high molecular weight, synthetized from acrylamide (AMD) and acrylic acid/acrylate (AA) (Scott et al. 1996; Caulfield et al. 2002).

Does Pam degradation affect flocculant performance?

PAM-based flocculant degradation has been mainly studied for PAMs in aqueous solutions. The degradation of PAMs results in a reduction of the molecular weight of the polymer and can adversely affect the performance of such aqueous solutions in their commercial application as flocculants.
