a double effect evaporator is fed by 31896 lbm/hr of 9% potassium chloride solution. At the end of evaporation a 41% KCl solution is obtained. The water evaporated in the second effect is 1.5 times the water evaporated in the first effect. Determine: a) The amount of 41% concentrated solution b) The amount of water evaporated in the first and second effects c) The amount of solution fed into the second effect, as well as its composition

Question

a double effect evaporator is fed by 31896 lbm/hr of 9% potassium chloride solution. At the end of evaporation a 41% KCl solution is obtained. The water evaporated in the second effect is 1.5 times the water evaporated in the first effect. Determine:
a) The amount of 41% concentrated solution
b) The amount of water evaporated in the first and second effects
c) The amount of solution fed into the second effect, as well as its composition

31 896 lbm/hr 9% KCI 91% H₂O M₁ M₂ Ma x KCI y H₂O M₁=1.5 M₂ Ma -> H₂O(vapor) M6 = M₂ Ma es el agua que condensa 41% KCI 59% H₂O
