An aqueous slurry at 30°C containing 20.0 wt% solids is fed to an evaporator in which enough water is
vaporized at 1 atm to produce a product slurry containing 35.0 wt% solids. Heat is supplied to the
evaporator by feeding saturated steam at 2.6 bar absolute into a coil immersed in the liquid. The steam
condenses in the coil, and the slurry boils at the normal boiling point of pure water. The heat capacity
of the solids may be taken to be half that of liquid water.

A Calculate the required steam feed rate (kg/h) for a slurry feed rate

Feed saline (salt) water containing 5 wt% dissolved solids and the balance water enters an evaporator plant. The purpose of the evaporator plant is to concentrate the saline solution and to reduce its volume before discharge to a nearby waste storage dam. The feed saline water entering the evaporator unit is concentrated by a factor of 5 (wt% basis). The throughput of the evaporator is limited to 150 kg/h. When the feed saline water flowrate exceeds 150 kg/h, the excess...

An evaporator with an area of ​​83.6 m2 and U = 2638 kcal / h m2 C is used to obtain distilled water to be fed into a boiler. Water from the pipe network containing 400 ppm of solids dissolved at 15 C is introduced into the evaporator. The evaporator operates under a pressure of 1 atm. For heating, saturated steam is available at 1.7 atm absolute. Calculate the amount of distilled water produced per hour when the outlet liquid...

Sugar solution needs to be concentrated to 55 wt.% in order to produce sugar crystal. Double effect evaporator with reverse feed configuration was used for this purpose. 5000 kg/h of 15 wt% sugar feed solution enters the second evaporator at 30°C. The absolute pressure in the second evaporator is 12.35 kPa. Saturated steam at 313 kPa enters the first evaporator and the vapor from this evaporator is used to heat the second evaporator. The overall coefficients are U1 = 2500...
