A single effect evaporator is being used to concentrate a feed of 5,000 lb/h of a cane sugar solution at 90 °F and containing a sugar content of 10 °Brix (°Brix = wt.% sugar) to 30 °Brix for use in a food process. Superheated steam at 3 MPa and 600°C is available for heating. The vapor space in the evaporator is at 1 atm absolute. The OHTC is 550 BTU/h·ft2 ·°F and the heat capacity of the feed is 0.92 Btu/lb·°F. The boiling point can be estimated using BPR (°F) = 3.24x + 10.95x2 , where x = wt. fraction of sugar in solution. The heat of solution is considered negligible and can be neglected. Calculate the area required for the evaporator and the amount of steam used per hour
