Sea el evaporador de la figura, donde se concentran 10000 kg/h de una disolución salina diluida de 5% en peso hasta una concentración del 30% en peso. Calcular el caudal másico de agua evaporada.

balance materia evaporador 1

Solución:

Balance global total: 10000 = x + y
Balance global parcial (sal): 10000  0;05 = x  0;3 + y  0
Resolviendo el sistema se obtiene: x=1667 kg/h; y=8333 kg/h.
