Anionic polyacrylamides (Dry)

Dry, linear, anionic polymer powder.

Dry anionic polyacrylamides are synthetic, water-soluble polymer compounds composed of long, linear chains with negatively charged anionic groups. These dry polymers are commonly used as flocculants in water treatment, mining, and papermaking industries, as well as in soil conditioning and oil recovery processes, offering versatile applications across various sectors.

Energy Sector

Dry anionic polyacrylamides are widely employed in the energy sector as viscosity modifiers in enhanced oil recovery (EOR) operations. These dry polymers can increase the viscosity of injected water, facilitating more effective oil sweeping from reservoirs and improving oil recovery rates. Additionally, they serve as friction reducers in pipeline transportation of crude oil and natural gas, cutting pumping costs and boosting flow efficiency. In geothermal energy production, dry anionic polyacrylamides assist in reducing the amount of suspended particles in geothermal fluids, thereby enhancing heat transfer efficiency and preventing equipment damage. Furthermore, in oil field cementing, they act as fluid loss additives, minimizing water loss from cement slurries to surrounding formations. This application ensures the integrity and strength of the cement sheath, provides zonal isolation, and supports the well casing, thus enhancing the durability of the well structure and preventing fluid migration and wellbore collapse.

Water Treatment

Dry anionic polyacrylamides are extensively utilized in water treatment as flocculants to remove suspended solids, turbidity, and other contaminants from water. These dry polymers work by aggregating particles into larger, more easily removable clumps, thus enhancing water clarity, alleviating the burden on filtration systems, and improving overall water quality. Moreover, dry anionic polyacrylamides are effective in treating wastewater from industries such as papermaking, mining, and food processing, as well as in municipal wastewater treatment plants. They improve the efficiency of settling tanks, bolster solid-liquid separation, and diminish sludge volume, thereby rendering wastewater treatment more effective and cost-efficient.

Pulp & Paper

Dry anionic polyacrylamides are commonly used in the pulp and paper industry as retention and drainage aids during the papermaking process. They enhance paper strength and reduce production costs by increasing the retention of fine particles and fillers in the paper sheet. Additionally, these dry polymers improve drainage rates and reduce water consumption by facilitating faster water removal from the paper sheet. Dry anionic polyacrylamides also serve as flocculants in wastewater treatment from paper mills, aiding in the removal of suspended solids and minimizing environmental impact.
