The fresh feed to the process is 10000lb/hr of a 40% aqueous NaOH solution. The fresh feed is combined with the recycled filtrate from the crystallizer, and fed to the evaporator where water is removed the produce a 50% NaOH solution, which in turn is fed to the crystallizer. The crystallizer produces a filter cake that is 95% NaOH crystals and 5% solution  that itself consists of 45% NaOH. The filtrate contains 45% NaOH.  Assume that the same production rate of NaOH flake occurs but the filtrate is not recycled, what would be the total feed rate of 40% NaOH have yo be then? Assume that the product solution from the evaporator still contains 50% NaOH.

Question

The fresh feed to the process is 10000lb/hr of a 40% aqueous NaOH solution. The fresh feed is combined with the recycled filtrate from the crystallizer, and fed to the evaporator where water is removed the produce a 50% NaOH solution, which in turn is fed to the crystallizer. The crystallizer produces a filter cake that is 95% NaOH crystals and 5% solution  that itself consists of 45% NaOH. The filtrate contains 45% NaOH. 

Assume that the same production rate of NaOH flake occurs but the filtrate is not recycled, what would be the total feed rate of 40% NaOH have yo be then? Assume that the product solution from the evaporator still contains 50% NaOH.
