Customize Acid Cooler
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. brings deep engineering capabilities in advanced heat transfer technology to the chemical industry. The Anode Protection Sulfuric Acid Cooler represents specialized expertise fundamental to achieving safe, efficient, and durable operations in modern sulfuric acid production facilities.
Equipment Function
The Anode Protection Sulfuric Acid Cooler functions as a shell-and-tube heat exchanger designed to lower the temperature of concentrated sulfuric acid (typically 93% to 99%) during drying and absorption stages in contact process plants. This equipment addresses the challenge of hot concentrated acid's extreme corrosiveness by employing anodic protection technology that maintains stainless steel surfaces in a passive, non-corroding condition.
Technology and Operation
The system utilizes anodic protection to maintain stainless steel components at a carefully controlled electrical potential within their passive range. This is achieved through a cathodic setup—either long cathodes through the shell or pin-shaped cathodes in nozzles—working with a reference electrode and potentiostat that manages DC power.
  • Protective Shield Formation: A small direct current triggers stable oxide film formation across internal surfaces, reducing corrosion rates by several orders of magnitude
  • Potential Monitoring: Continuous monitoring of electrical potential between steel and reference electrode with real-time current adjustments to maintain safe passive zone operation
  • Durable Construction: Robust design handles thermal stresses with smart features like rod-type baffles that minimize tube vibration while improving heat transfer performance
Value Proposition
  • Exceptional Corrosion Protection: Anodic protection prevents corrosive attack, enabling austenitic stainless steels to perform reliably in aggressive environments
  • Extended Equipment Life: Consistent maintenance of passive oxide film significantly increases service life compared to unprotected alternatives
  • High Heat Transfer Efficiency: Turbulent acid flow and efficient heat transfer surfaces enable precise process control and effective energy recovery
  • Operational Reliability: Stable protective parameters and smart monitoring features minimize acid leaks and unplanned downtime
  • Energy Recovery Capability: Safe operation at elevated temperatures (up to 160°C or more) enables recovery of high-grade waste heat, improving overall plant energy efficiency
Company Commitment
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. provides high-integrity cooling solutions with durable, low-maintenance equipment engineered to meet rigorous demands of large-scale sulfuric acid production, built for reliable long-term performance.
