Question
Transcribed Image Text:Example 5.4. Redo the Example 5.2. once again, but consider the case that there is no recycle of
the filtrate to be mixed with the fresh feed. Determine
(a) the amount of K2Cro, produced per hour and
(b) the rate that we need to evaporate water.
Without the recycle of the filtrate, we can re-draw the flow chart as shown on the next page.
We then try performing the balances around the whole process, as done previously.
