QI (40/100). A feed containing 5 wt% dissolved organic solids in water is fed to a doubleclector with backward food. The feed 30C enters the second effect and is concentrated to 25% solids. The boiling point rise can be considered negligible as well as the heat of solution. The saturated some for being is fed to the first effect at 165C. The temperature in the second effect is 40C. The best transfer coefficients are U.-2800 W/ mK, and U-4200 W/mK. If each effect has the same surface area, calculate the area Note: To solve the problem, concentrated solution can be estimated 1000 kg/h The heat capacity of the liquid solutions is -4.87 kjkg"C. 501004 04 000100 000100 0100 93 00010 0001 58 Q.DOLC 10 0.001 3 0001
