Thermal stability of sulfonated polymers - The EOR Alliance
Thermal stability of sulfonated polymers. A. Audibert (Institut Français du Petrole) | J-F. Argillier (Institut Français du Petrole). Abstract. Polyacrylamides which are used in oil applications i.e. polymer flooding and water based muds, are hydrolysed versus time and temperature.
Stability of Partially Hydrolyzed Polyacrylamides at Elevated Temperatures in the Absence of Divalent Cations we observed the highest level of thermal stability reported to date for these polymers. Our results provide considerable hope for the use of HPAM polymers in enhanced oil recovery at temperatures up to 120°C if contact
Polymers for Enhanced Oil Recovery Technology - ScienceDirect
Polymer for Enhanced Oil Recovery 2.1. Principle and mechanism Polymer is the material that plays an important role in the application of EOR technology, especially for hydrogel polymer. A typical polymer flood project involves mixing and injecting polymer over an extended period of time until about 1/3-1/2 of the reservoir pore volume has been
Stability of Partially Hydrolyzed Polyacrylamides at Elevated Temperatures in the Absence of Divalent Cations Abstract At elevated temperatures in aqueous solution, partially hydrolyzed polyacrylamides (HPAM) experience hydrolysis of amide side groups.
Polyacrylamide
Stability. In dilute aqueous solution, such as is commonly used for Enhanced Oil Recovery applications, polyacrylamide polymers are susceptible to chemical, thermal, and mechanical degradation. Chemical degradation occurs when the labile amide moiety hydrolyzes at elevated temperature or pH, resulting in the evolution of ammonia and a remaining carboxyl group.

thermal stability of the products [19–21]. However, the main portion in HAPAM is still the acrylamide segment which shows poor long-term thermal stability and salt tolerance. Meanwhile, increasing molecular weight of HPAM (maximum 35 × 106 g∙mol−1 to date) can achieve higher viscosity
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- How cationic polyacrylamide (PAMC) is prepared?
- Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.
- How effective is PAMC flocculation in turbid water clarification?
- Chemical and morphology structures of PAMC were characterized and analyzed. Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content.
