SHEARING AND MIXING PERFORMANCE OF ULTRAHIGH-MOLECULAR-WEIGHT HYDROLYZED POLYACRYLAMIDE (HPAM) SOLUTION IN A HELIXES STATIC MIXER

Shearing and Mixing Performance of Ultrahigh-Molecular-Weight Hydrolyzed Polyacrylamide (HPAM) Solution in a Helixes Static Mixer

Static mixers have been widely used to dilute high viscosity, high-molecular-weight polymer mother liquor for polymer flooding, in which the mixing performance plays a critical role.In this work, a novel mixing configuration, named as Helixes static mixer, was proposed to reduce high viscosity degradation rate of polyacrylamide solution resulting f
