Question 2 MSF desalination plant is used to produce fresh water under the following conditions: Recovery ratio, RR 0.09 GOR 7.795 Temperature of brine leaving the brine heater a 88.9 °C (192.0 °F) Process saturated steam temperature 103.6 °C (218.5 °F) Cp for brine 3.9 kJ/kgK (0.931 Btu/lb °F) Overall heat transfer coefficient 10220 kJ/hr m² K (500 Btu/hr ft? OF Latent heat of process steam 2246.9 kJ/kg (966.0 Btu/lb) Latent heat of the distillate 2358.6 kJ/kg (1014.0 Btu/lb) Area of brine heater 5.59 m² (60.153 ft) Find: a) the distillate temperature, if t4 =t3 - RR w/Cp. b) the temperature of brine enters the brine heater. c) the intake seawater temperature. d) the amount of the process steam in kg/hr (lb/hr). e) the amount of the distillate in kg/hr (lb/hr). f) the amounts of feed water and blowdown if the concentration of the blowdown = 1.5 th feed concentration.
