Meet your Sustainability goals with our Acid Recovery processes!

The Chemical industry produces thousands of tons of diluted inorganic waste acids containing inorganic and organic impurities. 

These acid waste streams are often neutralized prior to transfer to wastewater treatment facilities. However, rising operating costs in difficult economic times create the need to recover the acid for further use. Stricter environmental regulations globally also mandate recovery of acid rather than waste treatment.

Acid recovery capabilities

We offer Acid Concentration plants with process technology and a complete range of Engineering services provided by Pfaudler Systems Group, active in the field of acid treatment and all related services for decades. 

Our highly experienced team of Process Developers, Project Managers and Experts from all related disciplines evaluate the most appropriate process technology for the given application. 

The offered plant is based on the latest state of technical knowledge and all plant units are optimized with respect to investment costs and operability of the plant. The scope of supply is proven to be suitable in regards to safety and operability.

As Acid is highly corrosive ranging from low to high concentrations, Pfaudler offers corrosion-resistant materials such as glass-lined steel (Glasteel®), fluoropolymer-lined steel and reactive metals (Zirconium and Tantalum) technologies that help in the safe containment and processing for acid recovery. 

Our capabilities expand across the globe, designing and engineering plants for the following Acid recovery processes:

• Nitric Acid
• Spent Acids
• Sulfuric Acid
• Formic Acid
• Waste Water
• Acetic Acid
• HydroChloric Acid

Acid Concentration System Features

• Extensive experience in corrosion resistant equipment & system design. 
• Heat recovery systems integrated into design for substantial operational cost savings. 
• Multiple system designs including forced circulation, thermosiphon and multieffect for energy conservation. 
• Laboratory test facility allows for proof of concept/performance, optimization of design and data collection for commercial scale system design. 
• Emission control systems provided as an option to control organics, NOx and emissions when plant pollution control systems do not exist or are not designed for the additional load. 
• Utility systems designed and provided for plants were existing utilities are insufficient to service the Acid Concentration System 
• Control systems are included to provide for safe, reliable operation.
