This is a Chemical enginnering question for subject HEAT AND MASS TRANSFER 32
Regardless of feeding strategy, the first effect in a multiple-effect evaporator system is always the effect where
A. the feed is introduced first
B. the steam is introduced first
C. the finals product emerges from
D. The pressure is lowest.
Homework Answers
32) The first effect of a multiple effect evaporator is the effect to which the raw steam is fed, vapors obtained from the first effect act as the heating medium for another effect.

Separation Process Problem 1 [30 marks] A double-effect forward-feed evaporator is used to concentrate a 5 wt% aqueous NaCl solution to a final concentration of 25 wt% The feed enters the first effect at a temperature of 40°C. Saturated steam at a pressure of 2 bar (absolute) is fed to the first effect at a rate of 1500 kg/h, and the vapour from this effect is used to supply heat to the second effect. The overall heat transfer coefficient in...
