Anodically Protected Acid Heat Exchanger
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. has established a strong reputation in the chemical industry through advanced engineering and specialized heat transfer technology. Our Anode Protection Sulfuric Acid Cooler represents our commitment to excellence and has become an essential component in modern sulfuric acid processing operations.
Advanced Cooling Solution for Concentrated Sulfuric Acid
This specialized shell-and-tube heat exchanger is engineered specifically for cooling concentrated sulfuric acid in the 93% to 99% concentration range, typically used in drying and absorption sections of contact process plants. The system addresses the extreme corrosiveness of hot concentrated acid through innovative anodic protection technology.
Anodic Protection Technology
The core innovation lies in anodic protection—an electrochemical method that maintains stainless steel components in a passive, non-corroding state. This is achieved by precisely controlling the electrical potential of surfaces in contact with acid within the optimal "passive range" through a sophisticated system of cathodic components, reference electrodes, and potentiostat controllers.
Protective Oxide Formation
Application of controlled direct current initiates formation of a durable, invisible oxide film on all acid-contacting surfaces, reducing corrosion rates by orders of magnitude.
Continuous Monitoring & Control
Advanced controllers continuously monitor potential between steel and reference electrodes, making real-time adjustments to maintain optimal passive zone operation.
Robust Mechanical Design
Engineered with rod-type baffles and reinforced construction to withstand operational pressures while enhancing heat transfer efficiency.
Key Performance Advantages
  • Superior Corrosion Resistance: Enables safe use of austenitic stainless steels in highly corrosive environments, significantly enhancing operational safety
  • Extended Service Life: Maintains protective passive film integrity for years of reliable operation, far exceeding unprotected equipment longevity
  • Optimized Heat Transfer: Engineered for turbulent acid flow and maximum heat transfer surface utilization, delivering superior thermal performance and energy efficiency
  • Operational Reliability: Maintains consistent performance parameters with advanced monitoring systems, including remote diagnostics for proactive maintenance
  • Waste Heat Recovery: Capable of operating safely at temperatures up to 160°C and beyond, enabling efficient waste heat recovery and significant energy cost savings
Jiangsu Carpe Diem Ocean Equipment cooling systems represent engineered reliability and thoughtful design. Our equipment delivers maintenance-free performance in demanding large-scale acid production environments, built to provide years of dependable service and operational excellence.
