The solvent used in liquid extraction should not have high latent heat of vaporisation, because ______________________?
Correct answer: D. Its recovery cost by distillation may be prohibitively high
- A. The pressure drop and hence the pumping cost will be very high
- B. It cannot be recovered by distillation
- C. It will decompose while recovering by distillation
- D. Its recovery cost by distillation may be prohibitively high
Explanation
A solvent with high latent heat requires substantial energy for vaporisation during distillation recovery. Therefore, its recovery cost may become prohibitively high, even though the solvent can technically be recovered.
