Question
Q11 A solution containing 15.0wt%NaCl, 5.0wt% KCl, and 80wt%water is fed to an evaporator crystallizer process. The fresh feed stream mass flowrate is 1000 Kg/h, the fresh feed is added with the recycle stream, coming from the crystallizer stream, and enters an evaporator. In the evaporator, pure NaCl is collected at the bottom of the evaporator, and the top stream is pure water vapor. The evaporator outlet stream composition is 17wt% NaCl, 22wt% KCl, and 61wt% water enters to the crystallizer unit. Pure KCl is collected as bottom product from the crystallizer. The crystallizer outlet stream is entirely recycled and joins the fresh feed stream. The recycle stream contains 20wt% NaCl, the balance is water and KC1. Draw the process flow sheet Calculate the mass fraction of KCl in the recycle stream N2
