cator Single Effect Evaporator (SEE) is used to produce distilled water. The intake seawater temperature equal to 30 °C. The evaporator feed temperature is 5 °C lower than the temperature of vapor produced in the evaporator. Saturated Steam temperature equal to 100 °C is used. The salinity of the seawater and brine blow down are 35000 ppm and 70000 ppm; respectively. The specific heat transfer area of the evaporator equal to 120 m²/(kg/sec). Accordingly, Calculate the following: • Specific Feed = Brine blow down Temperature = • Performance Ratio = LMTD of the condeser = o Process Specific Area = °C U m²/(kg/sec)
Expert Answer
Solution: We can use the material balance equation across the evaporator as follows: F = Feed Flow = 14400 kg/h V = Vapor Flow (Water Distilled) L = Concentrated Liquid Flow xf = solid content in feed = 0.06% = 0.0006 xl = solid content in concentrat
