A single effect evaporator has a thermal load, Qe = 2355 kJ/s and the heating steam temperature is 115 °C. The seawater temperature, Tcw = 30 °C, and the feed seawater temperature, Tf, is less than the boiling temperature, Tb, by 10oC. The distillate product flow rate is to be 1 kg/s. Use the same salinity and flow rates given in Example 1 for the feed seawater and reject brine. Calculate: a) the boiling temperature, b) the heat transfer areas, and c) the flow rate of the cooling seawater.

Question
A single effect evaporator has a thermal load, Qe = 2355 kJ/s and the heating steam
temperature is 115 °C. The seawater temperature, Tcw = 30 °C, and the feed seawater
temperature, Tf, is less than the boiling temperature, Tb, by 10oC. The distillate
product flow rate is to be 1 kg/s. Use the same salinity and flow rates given in Example
1 for the feed seawater and reject brine. Calculate:
a) the boiling temperature,
b) the heat transfer areas, and
c) the flow rate of the cooling seawater.
