Multiple-Effect Evaporation of Sugar Solution
This simulation compares the efficacy of feedforward, multiple-effect evaporation to single-effect evaporation of a dilute sugar solution. In a multiple-effect evaporation process, the saturated vapor from one evaporator is fed into a heat exchanger in the next evaporator, which operates at a lower pressure to reduce the boiling point of the solution. You can adjust the flow rate and pressure of the feed solution. Percentages are by mass; that is, “5.00% sugar” represents 0.05 kg sugar per 1 kg of solution. All pressure drops occur adiabatically across valves, resulting in flash vaporization. The inlet stream to the first evaporator is saturated liquid, and the last evaporator in each process is held at atmospheric pressure. The single-effect evaporator has flash vaporization before the inlet.
