Anodic Protection Acid Heat Exchanger
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. has established itself as a trusted name in the engineering and supply of advanced heat transfer technology for chemical processing. Among its portfolio of specialized solutions, the Anode Protection Sulfuric Acid Cooler stands out—a piece of equipment that has become essential for any modern sulfuric acid plant aiming for safe, efficient, and uninterrupted operation.
Product Overview
This shell-and-tube heat exchanger is designed to cool concentrated sulfuric acid (93% to 99%) as it moves through the drying and absorption stages of contact process plants. The system employs anodic protection technology to prevent corrosion in aggressive high-temperature sulfuric acid environments where standard materials would fail.
Anodic Protection Technology
The anodic protection system maintains stainless steel components at a specific electrical potential within the passive range. The system includes cathodic setups (long cathodes through the shell or pin cathodes in nozzles), reference electrodes for monitoring, and a potentiostat as the DC power control center.
  • Protective Film Formation: A small direct current triggers formation of a stable oxide film on all internal surfaces, creating an effective corrosion barrier
  • Continuous Monitoring: The system constantly measures electrochemical potential and adjusts current in real-time to maintain the metal within the safe passive zone
  • Robust Construction: Engineered to handle significant thermal stress with features like rod-type baffles that reduce tube vibration while improving heat transfer
Key Benefits
  • Complete Corrosion Prevention: Stops corrosion entirely, allowing austenitic stainless steels to operate safely in aggressive environments
  • Extended Service Life: Maintains protective passive film integrity year after year, significantly increasing equipment lifespan
  • Enhanced Efficiency: Optimized design promotes turbulent flow and maximizes heat transfer surface utilization
  • Operational Reliability: Solid protective parameters with smart monitoring and remote diagnostics minimize acid leaks and unplanned shutdowns
  • Energy Recovery: Capable of operating safely at temperatures up to 160°C and beyond, enabling high-grade waste heat recovery
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. delivers comprehensive cooling solutions combining high-integrity equipment with extensive engineering expertise. Our systems are built to withstand the demanding requirements of large-scale sulfuric acid production, offering durability, low maintenance, and consistent performance.
