Problem 4 A brine circulation MSF system has the following operating data Feed salinity = 57000 ppm Brine blowdown salinity = 70000 ppm Heating steam temperature = 116C Production capacity = 1 kg/s Brine blowdown temperature = 40C Feed temperature = 30C Top brine temperature = 106C Terminal temperature difference in the condenser = 3C Number of stages = 24 (with 3 stages in the heat rejection section). Compare the system performance if the thermodynamic losses are equal to 1.5 C
