Evaporator Design
Single and multiple effect evaporator system design with steam economy analysis
Process Conditions
Evaporator Configuration
Steam temperature: 0.0°C
1000–2000 food, 1500–2500 chemical
Higher for concentrated solutions
Temperature Profile
Steam (Effect 1): 0.0°C
Effect 1 vapor:-4.0°C
Effect 2 vapor:-8.0°C
Effect 3 vapor:-12.0°C
ΔT per effect: 3.0°C
Design Recommendations
✓Significant steam savings vs single effect (58%)
ℹVery low ΔT per effect — consider reducing number of effects
