Polyacrylamide also finds extensive applications in the oil and gas industry, particularly in enhanced oil recovery (EOR) techniques. It is used as a thickening agent in the injection of water or gas into reservoirs, facilitating the extraction of oil from subterranean formations. By increasing the viscosity of the injection fluid, polyacrylamide enhances the displacement of oil and reduces the water-oil interfacial tension. This leads to improved recovery rates and a more efficient extraction process.
The 40 in its name signifies its concentration, with sodium cumene sulfonate being available in various concentrations depending on the intended application. The 40% concentration often denotes a balance between performance and cost-effectiveness, making it a popular choice among manufacturers and formulators.
The pH level of feed water is crucial for the efficient operation of an RO system. A pH that is too low (acidic) or too high (alkaline) can lead to membrane damage and decreased performance. pH adjusters, such as sodium hydroxide (caustic soda) or sulfuric acid, are used to stabilize the pH of the water entering the system. Maintaining the optimal pH range can enhance the solubility of minerals and improve the overall separation efficiency of the RO process.
