Polyacrylamide degradation and its implications in - Nature

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties

Nov 1, 2015 · Water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers are among the most commonly used chemicals in oilfield applications.

Oct 13, 2022 · Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.

Impacts of partially hydrolyzed polyacrylamide (HPAM) on

Constructed wetlands have been successfully used in the treatment of produced water brought to the surface in large quantities during oil extraction activities. However, with the increasing use of partially hydrolyzed polyacrylamide (HPAM) in enhancing oil recovery, the impacts of HPAM on the biological processes of wetlands is still unknown.

Introduction to polymer flooding and related agents, EOR

Hydrolyzed Polyacrylamide (HPAM) Polyacrylamides (PAM) are synthetic polymers available in both powder and liquid (emulsion) form (Needham & Doe, 1987; Chang, 1978; Donaldson et al., 1989). These polymers are manufactured in a variety of ways to yield a wide range of physical and chemical properties that make them candidates for many different
