Evaporation of Sugar Solution in a Multiple-Effect Evaporator. A triple-effect evaporator with forwarding feed is evaporating a sugar solution with negligible boiling- point rise (less than 1.0 K, which will be neglected) and containing 5 wt% solids to 25% solids. Saturated steam at 205 kPa abs is being used. The pressure in the vapor space of the third effect is 13.65 kPa. The feed rate is 22 680 kg/h and the temperature 299.9 K. The liquid heat capacity is c. - 4.19 -2.35 x, where Cp is in kJ/kg.K and x in wt fraction (K1). The heat-transfer coefficients are U, - 3123, U = 1987, and Ug = 1136 W/m².K. Calculate the surface area of each effect if each effect has the same area and the steam rate?
