Polyacrylamide degradation and its implications in

High MW anionic PAM is also the most commonly applied polymer in enhanced oil recovery applications; the use of surfactant-polymer flooding can increase oil recovery by 5¨C30% 14 and in...

environmental impurities. Analysis of PAM in oil sands tailings or oil sands process water is challenging for two main reasons: (1) the compounds vary widely in terms of chemical properties; and (2) they are highly adsorptive within a complex matrix of OSPW and tailings. PAM Degradation PAM is applied to tailings at all operating oil sand mines.

Partially hydrolyzed polyacrylamide: enhanced oil recovery

So, reservoir permeability, rock composition, and oil viscosity are important in the selection of the applied polymer in the field (Abidin et al., 2012). Problems associated with PAM and HPAM As a byproduct from oilfields using the polymer flooding method, produced water is contaminated with HPAM even after conventional treatment (Al-Sabahi et ...

aerobic degradation of anionic polyacrylamide in oil sands

Aerobic degradation of anionic polyacrylamide in oil sands

An investigation was carried out to study the degradation of anionic polyacrylamide (A-PAM) under different temperature and microorganism conditions as well as to assess its effects on water chemistry and toxicity in oil sands tailings. The maximum removal efficiency of A-PAM was 41.0 % in tailings water with augmented microorganisms at 20 ¡ãC.

Turbidimetric Determination of Anionic Polyacrylamide in Low

Previous studies determined that the methods based on hyamine had detection limits of 0.5 to 1 mg L ?1 for dissolved PAM in either deionized (DI) water or oil-field brines (Crummett and Hummel, 1963; Allison et al., 1987; Taylor and Nasr-El-Din, 1994). These results suggest that the hyamine test may be useful for quantifying PAM in ...
