Expert Solution

One good example of Energy balance equation is single effect evaporator.

The schematic of a single effect evaporator is shown in figure. In oredr to develop the governing equations of the system we aasume

i> steady state

ii> no heat loss in the surrounding

iii> no entrainment of the liquid droplets(y=0)

iv> only latent heat is transferred from the steam side

with the stated assumptions, the governing balance equations are

overall material balance : F = V +L

component balance (solute): FZF = Lx

energy balance equation: ........1>

where

subcooled heat load

Latent heat load

Total heat load = subcooled heat load + Latent heat load

Another energy equation can be written as

capacity equation : ........2>

1 and 2 equations are energy balance equation.

Parameter used here are:

F = feed flow rate

ZF= inlet feed composition

tF= inlet feed temperature

V= vapour to condenser

= steam flow rate

= latent heat of steam

L = liquid flow rate

x =lquid composition

Q = total heat

tSt = steam temperature

tF = feed temperature

ts = saturation temparature
