Single-Effect Evaporator. A feed rate of 20410 kg/hr of 10 wt % NaOH solution at 48.9 °C is being concentrated in a single-effect evaporator to produce a 50% solution. Saturated steam at 178.3 °C is fed to the evaporator and the pressure in the vapor space is 10.34 kPa abs. The heat-transfer coefficient is assumed to be 2840 w/m?-K. Calculate the heat-transfer area, the steam consumption rate, and the steam economy.
