Determine the unit product cost for 120,000 m3 /d MED unit using the following economic data composed of 20 effects : Plant capital = $280,000,000 Electric power cost = $0.05/m3 . Annual interest rate = 7% . Economic life = 30 years . Specific electric power consumption = 4.2 kWh/m3 . Heating steam cost = $1.5/MkJ . Latent heat of heating steam = 2200 kJ/kg . Plant factor = 0.9 Chemicals cost = $0.019/m3 . Labor cost = $0.095/m3 . Plant performance ratio = 19 B) Analyze the following parameters on the unit production cost: a. The impact on the unit product if we change the number of effects from 4 to 20 effects b. The impact of unit product if we change the salinity from 42,000 ppm to 84,000 ppm c. The impact of unit product if we change the temperature of heating steam from 60C to 120 C
