Question
A single effect evaporator is being used to concentrate 8000 kg/h of tomato juice from 5% total solids to 30% total solids. The juice enters the evaporator at 25°C. The evaporator is operated with steam (85% quality) at 143.27 kPa. The vacuum inside the evaporator allows the juice to boil at 75°C. The specific heat of the liquid feeds is 4.1 kJ/(kg°C) and the concentrated product is 3.1 kJ(kg°C)
Calculate
a. The steam requirements = ... kg/h
b. Steam economy for the process. Assume the condensate is discharged at 75°C
