Anionic polyacrylamides

Water-soluble, linear, anionic polymer compound.

Anionic polyacrylamide is a synthetic, water-soluble polymer compound consisting of long, linear chains with negatively charged anionic groups. It is commonly used as a flocculant in water treatment, mining, and papermaking industries, as well as in soil conditioning and oil recovery processes.

Energy Sector

In the energy sector, anionic polyacrylamide is commonly used as a viscosity modifier in enhanced oil recovery (EOR) operations. It can increase the viscosity of injected water, allowing it to sweep more oil from the reservoir and improve oil recovery rates. Additionally, it is used as a friction reducer in pipeline transportation of crude oil and natural gas, reducing pumping costs and enhancing flow efficiency. Anionic polyacrylamide is also used in geothermal energy production, where it aids in reducing the amount of suspended particles in geothermal fluids, thus improving heat transfer efficiency and preventing equipment damage. In oil field cementing, anionic polyacrylamide acts as a fluid loss additive, minimizing the loss of water from cement slurries to the surrounding formations. This ensures the integrity and strength of the cement sheath, providing zonal isolation and support for the well casing. Its application in cementing operations enhances the durability of the well structure, preventing fluid migration and securing the wellbore against collapse.

Water Treatment

Anionic polyacrylamide is widely used in water treatment as a flocculant to remove suspended solids, turbidity, and other contaminants from water. It works by aggregating particles and forming larger, more easily removable clumps. This improves water clarity, reduces the load on filtration systems, and enhances overall water quality. Additionally, anionic polyacrylamide can be used to treat wastewater from industries such as papermaking, mining, and food processing, as well as municipal wastewater treatment plants. It can improve the efficiency of settling tanks, enhance solid-liquid separation, and reduce sludge volume, thus making wastewater treatment more effective and cost-efficient.

Pulp & Paper

Anionic polyacrylamide is commonly used in the pulp and paper industry as a retention and drainage aid during the papermaking process. It improves paper strength and reduces production costs by increasing the retention of fine particles and fillers in the paper sheet. Additionally, it improves drainage rates and reduces water consumption by increasing the rate of water removal from the paper sheet. Anionic polyacrylamide is also used as a flocculant in wastewater treatment from paper mills, aiding in the removal of suspended solids and reducing environmental impact.
