Partially hydrolyzed polyacrylamides with superior
A versatile process for the manufacture of PHPA has been developed. The applicability of this process for the production of PHPA in the field has been demonstrated. Based on performance in radial disk floods, Marathon PHPA's exhibit ideal mobility behavior. The superior performance of the Marathon
Polymer flooding is the most successful chemical method to enhance oil recovery. This technique has achieved large-scale field application in China. Polymer flooding is also being tested in several heavy oil fields. For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery.

The Behavior of Partially Hydrolyzed Polyacrylamide
Experimental Polymer Solutions Polymer Solutions Samples of three different partially hydrolyzed polyacrylamides were examined; all were furnished by polyacrylamides were examined; all were furnished by the same commercial supplier. The three types were all substantially linear and differed mainly in molecular weight.
Summary. At elevated temperatures in aqueous solution, partially hydrolyzed polyacrylamides (HPAMs) experience hydrolysis of amide side groups. However, in the absence of dissolved oxygen and divalent cations, the polymer backbone can remain stable so that HPAM solutions were projected to maintain at least half their original viscosity for more than 8 years at 100°C and for approximately 2

1. Introduction - Hindawi Publishing Corporation
Currently, the common used oil displacement agent is partially hydrolyzed polyacrylamide (HPAM), the viscosity of which, however, descends drastically with the increase of temperature and salinity [1].Hence, along with the continuous development of oilfield and with the increasing severity of reservoir conditions, polyacrylamide should be improved in molecular weight or by increasing polymer
4.4.2.1 Partially Hydrolyzed Polyacrylamide. Partially hydrolyzed polyacrylamides are the most common synthetic polymers utilized in polymer flooding. They are synthetic dynamic linear acrylamide monomers chains. They are made with a 30% hydrolysis extent, but it can be either increased or decreased.

- 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.
- Why is polyacrylamide used in water treatment and sludge dewatering?
- Polyacrylamide and its copolymers are extensively employed in water treatment and sludge dewatering. The efficiency of flocculation is influenced by factors such as the type of flocculant used, its molecular weight, and its concentration in the water suspension.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
- What is nonionic polyacrylamide used for?
- Nonionic polyacrylamides are available from very low to very high molecular weights and are used in industrial wastewater treatment, mineral process, papermaking, and other industries. High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5.
