Question

The volume of a steady-state crystallizer is 85,000 L, and the solids fraction in the unit and the exiting stream is 0.340; that is, there are 0.340 kg of crystals per kg of slurry (the mixture of solid crystals and solution). The density of the solution is 1.15 g/mL and that of the crystals is 2.10 g/mL. The production rate of crystals from the crystallizer is 19.5 kg crystals/min.
Required:
Estimate the volumetric flow rate of slurry from the crystallizer and the drawdown time of the crystallizer (the time it would take to empty the crystallizer if the feed were discontinued).
