A multiple effect evaporator as compared to a single effect evaporator of the same capacity has _________________?
Correct answer: A. Higher steam economy
- A. Higher steam economy
- B. Lower steam economy
- C. Lower heat transfer area
- D. Higher solute concentration in the product
Explanation
In a multiple-effect evaporator, vapour from one effect supplies heat to the next, allowing the same steam to evaporate more solvent. Thus steam economy is higher than for a single-effect unit of comparable capacity.
