Evaporative Crystallization with Recycle
This simulation shows mass balances for an evaporative crystallization process. A 15% potassium chloride/85% water feed is mixed with a recycle stream and fed to an evaporator, which evaporates water and increases the KCl concentration in the exiting solution. This solution enters a crystallizer and filter. A filter cake of KCl crystals and a portion of the saturated KCl solution are removed from the crystallizer and filter. The rest of the KCl solution is recycled and mixed with the fresh feed. Use sliders to set the fraction of crystals in the product stream, and the temperatures of the evaporator and crystallizer/filter. The solubility of KCl increases linearly with temperature.
