6.

   An evaporator is fed with 25 tons/hr of a solution containing 10% NaOH, 10% NaCl and 80% water. The water is evaporated and NaCl crystals removed. When they leave the evaporator the NaCl crystals carry with them 0.12 lbm solution/lbm crystals. The concentrated liquor leaving the evaporator contains 50% NaOH, 2% NaCl and 48% water. Assume that the solution adhering to the crystals has the same composition as the concentrated liquor. Find

The water evaporated in lbm/hr

The amount of concentrated liquor in lbm/hr.

500 kg/h of an aqueous solution containing 35% masses of a certain salt are fed to a system that produces crystals from this pure salt. The stream in question is mixed with a recirculation that comes from a crystallizer-filter. The mixture of both streams is charged to an evaporator and the concentrated solution is fed to a filter-crystallizer . The filter cake consists of 94 % pure crystals and the balance of the residual solution . Considering that the rate...

An aqueous caustic stream mixture containing 20% (by weight) sodium hydroxide (NaOH) is fed to an evaporator to remove 50% of the water in the feed stream. Draw and label a PFD of the process. Using a Degree of Freedom analysis show that there is insufficient information to allow you to balance the PFD. If you assume a basis of a feed stream of 100 kg/h can you now proceed? If so calculate all unknown stream flows and compositions. Express...
