Chemical Degradation of Polyacrylamide Polymers Under
The hydrolysis of polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers at elevated temperatures was noted by Muller et al., (1980, 1981a, 1981b) and Shupe (1981) due to the increase of viscosity, change in pH, and evolution of ammonia observed in PAM solutions aged at elevated temperature, as well as precipitation
Abstract There are many oil reservoirs worldwide with substantial amount of H 2 S but otherwise very favorable conditions for polymer flooding such as low temperature, high permeability, and moderate to high oil viscosity. However, there is a legitimate concern about the chemical stability of polymers when there is dissolved oxygen in the injection water or injection facility and its high
Chemical Stability of Polyacrylamide Under - OnePetro
The approach of this project was to study the chemical stability of polyacrylamide solutions under "simulated" field conditions. The variables of this study, which are often encountered by a polymer solution in the field, are the following: oxygen, temperature, oxygen scavenger, metal/metal ion, hydrogen sulfide, pH, salinity/hardness, chemical

Polyacrylamide polymer for oil contamination purity
Chemical Stability of Polyacrylamide Polymers OnePetro. Summary A comprehensive study of the chemical stability of polyacrylamide (PAA) polymers was conducted. The primary emphasis of the study was to determine the stability of Dow Pusher TM 500 PAA in Sundance brine a 115 deg. 17 (46 deg. C). Experiment. Cited by: 103
In addition, because large quantities of chemical are required to flood developed fields, many polymer manufacturers have directed their efforts toward this substantial potential market. Several chemical companies have acquired extensive technology in the manufacture of water-soluble polymers, but most of them lack expertise in the polymers
Screening of Polymers for EOR in High - OnePetro
Abstract Polymer flooding is one of the most attractive chemical EOR techniques for sandstone reservoirs however due to complex geological heterogeneity and harsh reservoir conditions its full potential has not been explored in carbonate reservoirs.

- Can polyacrylamide coagulation improve sludge dewatering performance?
- Enhancing sludge dewatering can effectively reduce the operational costs of wastewater treatment plants. In the present study, a synergistic process combining polyacrylamide (PAM) coagulation with Fe 2+ /CaO 2 Fenton-like oxidation was proposed to improve the performance of sludge dewatering.
- Can Pam / Fe2+ / Cao 2 treatment improve sludge dewatering performance?
- Pre-addition of PAM before Fe2+ /CaO 2 treatment can achieve better sludge dewatering performance. The dewatering mechanism of PAM/Fe 2+ /CaO 2 treatment was elucidated. Enhancing sludge dewatering can effectively reduce the operational costs of wastewater treatment plants.
- How flocculation improve sludge dewatering performance in water supply plants?
- Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.
- Does Pam dosing order affect sludge dewatering?
- To evaluate the influence of PAM dosing order on sludge dewatering, a series of experiments with adding PAM before adjusting pH were carried out. Following the conditioning procedure, the pH value of the sludge was gauged.
