Partially hydrolyzed polyacrylamide: enhanced oil recovery applications, oil-field produced water pollution, and possible solutions

Polyacrylamide and partially hydrolyzed polyacrylamide Polyacrylamide (PAM) is a synthetic polymer of long-chain acrylamide subunits, high molecular weight (1000 to 20 ¡Á 10 6 g/mol), and a wide range degree of hydrolysis (Abidin et al., 2012 ; Joshi & Abed, 2017 ).

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) 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 [ edit]

Herein, a new hydrolyzed-polyacrylamide (HPAM) gel is developed to control high-permeable producing water zones using chromium (III) sulfate as an affordable metallic crosslinker. Resulting gel was associated with syneresis (water expulsion from gel body) at 82¡ãC which mitigated with bentonite and phenolic resin.

Hydrolyzed polyacrylamide biotransformation during the formation of anode biofilm in microbial fuel cell biosystem: Bioelectricity, metabolites

1. Introduction At present, the oilfield is facing the status quo of urgent disposal of hydrolyzed polyacrylamide (HPAM)-containing wastewater. Biodegradation technologies played an irreplaceable important role in the treatment of typical pollutant HPAM from oilfield (Zhao et al., 2020).).
