Single Effect Evaporator
A single-effect evaporator is concentrating 40,000 lbm/hr of a polymer solution from 10 to 50 wt% polymer with a water solvent. The feed is a saturated liquid at the evaporator pressure.
The condenser operates at 0.26 psia, the steam chest at 25 psia. The overall U = 400 BTU/(hr*ft2*F).
The engineer who designed the system says there is no boiling point elevation.
What heat transfer surface area is required?
