While Poly Aluminium Chloride (PAC) is most recognized for its critical role in water and wastewater treatment, its unique chemical properties lend themselves to a surprisingly diverse range of industrial applications. Beyond its primary function as a coagulant, PAC serves as a valuable chemical auxiliary and performance enhancer in sectors such as papermaking, oil and gas, and even in the manufacturing of consumer products. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality PAC that meets the specific needs of these varied industrial processes.

PAC in the Papermaking Industry

The paper and pulp industry relies heavily on chemical additives to control various stages of production and improve the quality of the final product. PAC finds several important applications here:

  • Sizing Agent: PAC is used as a crucial internal sizing agent in papermaking. It helps to impart water resistance and improve the printability of paper by controlling the penetration of water-based inks.
  • Retention and Drainage Aid: In the papermaking slurry, PAC aids in retaining fine particles, fillers, and pigments within the paper sheet, preventing their loss into the white water. It also improves drainage, allowing water to be removed more efficiently from the pulp.
  • Wastewater Clarification: As mentioned previously, PAC is highly effective in treating the wastewater generated from papermaking processes, removing suspended solids and improving water quality for discharge or recycling.

Applications in the Oil and Gas Industry

The oil and gas sector utilizes PAC in several critical processes:

  • Drilling Fluids: PAC can be used as an additive in drilling muds to control rheology and filtration properties. It helps to stabilize the borehole and improve drilling efficiency.
  • Oil-Water Separation: In upstream and downstream operations, PAC acts as an effective demulsifier, helping to separate crude oil from produced water or to break emulsions in refinery wastewater. This improves the quality of recovered oil and treated water.
  • Produced Water Treatment: PAC is used to clarify produced water, removing suspended solids and oil before disposal or reinjection.

Other Diverse Industrial Uses of PAC

The versatility of PAC extends to several other sectors:

  • Textile Industry: Beyond wastewater treatment, PAC can be used in certain textile dyeing and finishing processes to improve dye fixation and fabric properties.
  • Leather Tanning: In leather processing, PAC can act as a basic component in tanning agents, contributing to the stabilization of collagen fibers.
  • Construction: PAC can be used as an additive in concrete formulations to accelerate setting times and improve strength properties.
  • Personal Care Products: Certain grades of PAC, particularly aluminum chlorohydrate, are used as active ingredients in antiperspirants and deodorants due to their astringent properties.
  • Catalysis: PAC can serve as a catalyst or catalyst support in various chemical synthesis reactions.

Choosing the Right PAC for Your Application

The efficacy of PAC in these diverse applications depends on selecting the appropriate grade and form. Factors such as basicity, purity, particle size (for powder), and concentration (for liquid) are critical. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of PAC products tailored for specific industrial needs, ensuring optimal performance and value.

Conclusion

Polyaluminium Chloride is far more than just a water treatment chemical. Its complex chemistry and resultant properties make it a highly versatile compound with significant applications across a spectrum of industries. By understanding and leveraging these diverse uses, industries can harness the full potential of PAC to enhance their processes, improve product quality, and achieve greater operational efficiency.
