Thabelo cc (lid cc (ltd), is a juice manufacturing plant situated in the eastern cape. a backward feed triple effect ev triple effect evaporator is fed at 5 000 kg/h with an orange juice concentrate that contains 5 e solids. the temperature of the feed is 27°c. the specification of the final juice trate is 27 mass% solids. steam is available at 265 kpa and the vapour pressure in the second effect is 13.4 kpa. additional information: a. the bpr can be estimated by: bpr("c) = 1.65 x+5.35 x b. the heat transfer surfaces are the same in all three effects c. the heat capacity of the solution is 4.3 kj/kg k and is constant over temperature and concentration ranges d. the heat of the solution is negligible e. the overall heat transfer coefficients are estimated as u= 3.089, u2= 1.954 and u3= 1.127 kw/m2k f. perform only one iteration a. as the feed enters as a cold stream the first effect requires more heat. normally we need to adjust the temperature at1, at2, at3 proportionately. in this case, adjust art by increasing the temperature by 3 k at2 by decreasing the temperature by 1.4 k and at3 by decreasing the temperature by 2.95 k. 31. draw a schematic diagram to depict the evaporation process labelling all process streams and showing all information required for the system. 3.2. determine the amount steam required for the process. 3.3. determine the overall steam economy. 3.4. determine the area of each effect.
