This in turn increases the heating surface required to achieve a given evaporation rate. The product residence time will also increase.
The main feature of multiple effect evaporators are as follows: The waste equations are written for each treatment in a mathematical plant of a essay effect evaporator system. The enthalpy balance equations ii.
The heat transfer rates iii. The phase equilibrium relationship iv. The water balance equations 3.
