Design Calculation (Sizing) Of A Crystallizer
Problem Statement And Given Data: Given the following data and information, it is required to design a forced circulation crystallizer of the type shown in Figure 1 operating under vacuum. Figure 1 Forced circulation (FC) evaporation crystallizer. Feed (an aqueous solution) rate, Qi = 15 m 3 /h, feed concentration, Ci = 200 kg/m 3 solution; feed temperature = 55 o C; average density of the solution = 1100 kg/m 3 and average specific heat = 0.90 kcal/kg. o C; operating pressure = 100 mm Hg (660 mm Hg vacuum); boiling point elevation of the saturated solution = 13 o C; saturation concentration at the crystallization temperature = 250 kg/m 3 ; magma density allowed, M T = 350 kg crystal/m 3 solution; crystal growth rate determined experimentally under the conditions of the crystallizer, G = 4.67 x 10 -8 m/s; crystal density = 1700 kg/m 3 ; desired dominant crystal size L D = 0.8 mm; heat of vaporization of water at the temperature of the crystallizer = 570 kcal/kg...

To provide you with pure drinking water, Multiple comes with RO-UV purification technology. The water first passes through the RO membrane that removes all the harmful chemicals. The UV purification stage removes all the microbiological organisms. To add minerals to the drinking water, Multiple comes with a Mineral cartridge. The purification process of the water purifier is mentioned below.
