4) A solution of sugar in water is to be concentrated from 4% by weight to 20% by weight. The solution is fed continuously to a column through which air is bubbled. Air enters at the bottom of column and exits at the top of the column. Entering air has a dry bulb temperature of 45 °C and 10% RH. Exiting air is saturated at 100 % RH. The humidification of air is considered adiabatic process. a) Make a sketch of the process and put all the information given b) What are the humidities of entering and exiting air? c) Make a sugar balance and water balance to calculate how many kilograms of dry air must be bubbled through column per kilogram of entering sugar solution. d) Mark the process on the psychrometric chart.
