cationic polyacrylamide for water treatment of paper in luxembourg
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.
