Compressor pure water vapor, A Melter 1000 kg/hr Chilled sea water foed 3.45% NaCI Pure tresh chilled water, W Flash freezer Pure lce C Ice + brine B 4.8% NaCi Filter Chilled brine, D 6.9% Naci Figure 1 (Question #3) Figure 1 shows a schematic for making fresh water from sea water by freezing. The pre-chilled sea water is sprayed into a vacuum at a low pressure. The cooling required to freeze some of the feed sea water comes from evaporation of a fraction of the water entering the chamber. The concentration of the brine stream, B, is 4.8% salt. The pure salt-free water water vapor is compressed and fed to a melter at a higher pressure where the heat of condensation of the vapor is removed through the heat of fusion of the ice which contains no salt. As a result, pure cold water and concentrated brine (6.9%) leave the process as products Determine the flow rates of stream W , if the feed is 1000 kg per hour?
