Water 2 (W only) 3 Cold Solution Hot Solution (A+W) crystallization 4 Crystals (A only) (A+W)

The flowsheet below describes a crystallization process.  A hot solution of water (W) and a substance A enter the crystallizer.  Some water evaporates and exits the crystallizer through stream 2, while pure crystals of A are formed and collected in stream 4.  The remaining water and A solution exits through stream 4.  It is known that:

• 128 kg/hr of a 36.7 wt% of A solution enter the process
• 6.0% of the incoming water evaporates
• The exiting solution contains 27.2 wt% of A.

Calculate the production rate of crystals in kg/hr.  Use two decimal digits in your answer (e.g. 100.34)
