What is the steam economy in case of a single effect evaporator system ?
Correct answer: C. < 1
- A. 1
- B. > 1
- C. < 1
- D. 0.1
Explanation
In a single-effect evaporator, the steam economy is generally less than 1 because one kilogram of steam evaporates less than one kilogram of solvent after accounting for heat losses and sensible heating. Multiple-effect systems improve economy by reusing vapour heat.
