Custom Heat Exchanger For Sulfuric Acid
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. specializes in chemical plant hardware and heat transfer equipment designed for demanding industrial applications. Their expertise focuses on the Anode Protection Sulfuric Acid Cooler, engineered specifically for handling concentrated acids in chemical processing.
Advanced Shell-and-Tube Design
This shell-and-tube heat exchanger is purpose-built for cooling hot sulfuric acid in concentrations ranging from 93% to 99%, typically used in the drying and absorption stages of contact plants. Standard steel components quickly corrode when exposed to hot acid, making anodic protection technology essential for long-term durability and performance.
Anodic Protection Technology
The system maintains steel components at a precise electrical potential within the "passive zone" to prevent corrosion. This is achieved through three key components:
  • Cathode Assembly: Long rods through the core or pins in the nozzles
  • Reference Electrode: Monitors environmental conditions
  • Potentiostat: Controls DC current to maintain optimal potential
Operational Process
Protective Film Formation: A small DC current initiates the formation of an invisible oxide film that dramatically reduces corrosion rates by orders of magnitude.
Continuous Monitoring: The system constantly monitors the potential between steel and electrode, making immediate adjustments to maintain the optimal passive zone and prevent both active corrosion and transpassive conditions.
Robust Construction: Features like rod baffles provide structural stability while enhancing heat transfer efficiency through turbulent flow patterns.
Key Advantages
Superior Corrosion Resistance
Anodic protection enables stainless steel to withstand sulfuric acid environments where it would normally fail rapidly.
Stable Protective Film
The oxide film remains intact under varying conditions, preventing gradual deterioration of components.
Enhanced Heat Transfer
Turbulent flow optimization maximizes thermal efficiency and minimizes energy losses.
Reliable Operation
Consistent performance with remote monitoring capabilities and reduced unexpected downtime.
High Temperature Capability
Safe operation at 160°C and above, enabling effective waste heat recovery and reuse.
Delivered Performance
Jiangsu Carpe Diem Ocean Equipment delivers coolers engineered for reliability in demanding acid plant environments. These systems are built to withstand aggressive chemical processing conditions while maintaining operational efficiency and structural integrity over extended service life.
