Question
Solve the following exercise: There is a solution of organic colloids, which is concentrated in water from 12% to 47% in a simple effect evaporator. The water vapor is at a pressure of 150 kPa and the pressure in the evaporator is 13.60 kPa. The feed rate to the evaporator is 12300 kg/h. The overall heat transfer coefficient is taken to be 1600 W/m2 °C. The solution has negligible boiling point elevation. Calculate the heating surface required if the feed temperature is 27.3 °C, plus the steam consumption. The feed heat capacity is 3.2 kJ/kg*K. 12300kg/h Tf 12%solids Ts Pman=150kPa F s T1 P1=13.60 kPa S L 47% solids
