Question

Chemical Engineering Calc.

1. A material containing 75% water and 25% solid is fed to a granulator at a rate of 4000 kg/hr. The feed is premixed in the granulator with recycled product from a dryer which follows the granulator (to reduce the water concentration of the overall material in the granulator to 50% water. 50% solid). The product that leaves the dryer contains 16.7% water. In the dryer, air is passed over the solid being dried. The air entering the dryer contains 3% water by weight (mass) .and the air leaving the dryer contains 6% water by weight (mass).

a) What is the recycle ratio to the granulator?

b) What is the rate of air flow to the dryer?

*note: please do not forget to draw the flow chart diagram. please do not copy from any other sites such do not take any answers from other sites. Please provide easy to understand solution (detailed with given, required, and solutions) in orderly manner.
