Determine the heating area required for the production of 4535.9 kg/h of 50% NaOH solution from a 10% NaOH feed entering at 37.8oC. Evaporation is to be carried out in a single-body standard evaporator for which an overall coefficient of 2839 W/m2.K is expected. Steam is available saturated at 446.09 kPa and the evaporator can be operated at 32.4kPa. (A = 137.07 m2)

An evaporator is used to concentrate 4536 kg/h of a 20% NaOH solution entering at 60?C to a product of 50% solids. The pressure of the saturated steam used is 170 kPa and the vapour space pressure of the evaporator is at 12 kPa. The overall coefficient U is 1560 W/m2K. Calculate the steam used, the steam economy (kg vaporized / kg steam used) and the heating surface area.
