Premium Kettle Type Reboilers for Efficient Vapor Generation

Maximize Process Efficiency & Reliability with Industrial Kettle Type Reboilers

What is a Kettle Type Reboiler?

A Kettle Type Reboiler is a specialized shell-and-tube heat exchanger used for reboiling applications in chemical, petrochemical, and oil & gas industries. It works by vaporizing a portion of the bottom liquid from a distillation column to provide the necessary heat for the separation process.

At Yuhong Group, our kettle-type reboilers are engineered for:

• High heat transfer efficiency
• Ease of maintenance
• Reliable performance under continuous operation

The design typically includes a kettle drum (shell side) where liquid collects and a tube bundle for vapor generation. The excess liquid leaves as bottoms product, while generated vapor returns to the distillation column.

General Construction & Design Standards

• Design Codes: ASME Section VIII, TEMA Standards, API 660 (as applicable)
• Heat Transfer Area: Typically ranges from 10 m² to 1500 m² (customizable)
• Flow Arrangement:
  • Tube Side: Heating medium (e.g., steam, hot oil)
  • Shell Side: Process fluid to be vaporized
• Bundle Type: Removable U-tube or straight tube with floating head for easy maintenance

Technical Specifications

• Operating Pressure: Up to 40 bar (depending on material and design)
• Operating Temperature: Up to 400°C (with suitable materials)
• Vapor Load Handling: Designed for large vaporization rates
• Vapor Space: Sufficient for disengagement to avoid liquid carryover
• Typical Heat Duty: 0.5 MW to 25 MW (custom-designed)
