Determine the amount of steam to be consumed, the economy, and the heating area required, for the production of 10,000 Ib/hr of 50 % NaOH solution from 10 % NaOH feed entering at 100 °F. Evaporation is to be carried out in a single body, standard evaporator for which an over-all coefficient of 500 Btu/hr sq. ft. °F is expected. Saturated steam is available at 50 psig and the evaporator can be operated at 10 psi vacuum relative to a barometric pressure of 14.7 psia.
