a solution of organic colloids is to be concentrated from 15 to 50 percent solids in a vertical-tube evaporator. The solution has a negligible elevation in boiling point, and the specific heat of the feed is 0.93. Saturated steam is available at 0.8 atm abs, and the pressure in the condenser is 100 mmHg abs. The feed enters at 15 degree celsius. The overall coefficient is 1,700 W/m2.  The evaporator must evaporate 25, 000 kg of water per hour. How many square meters of surface are required, and what is the steam consumption in kilograms per hour?

Reactive Processes

Reactive processes are the processes in which any reaction occurs. The reactions can be any combination reaction, decomposition reaction, combustion reaction, oxidation reaction, reduction reaction, neutralization reaction, displacement reaction, or double displacement reaction.
