An evaporator concentrates the F kg / h feed containing 20 wt% NaOH at 311 K to the product containing 50 wt% NaOH. The temperature of the saturated water vapor used for heating is 399.3 K. Absolute pressure in the separator part of the evaporator is 13.3 kPa. The overall heat transfer coefficient is 1420 W / m2.K and the area is 86.4 m2. Calculate the feed rate F to the evaporator.

Distillation

Distillation is a process/technique to separate more volatile components from less volatile components using the principle of relative volatility. In chemical engineering, distillation is one of the most common and important topics that is involved in almost every industry and process.
