For dry gas and liquid water at 25°C, the following enthalpies are computed for the inlet- and exit-gas streams (basis, 100 kmol of gas entering):
Water vapor 4(10,490) = 41,960
Exit gas (assumed saturated with water at 25°C): Acetone (2/400)(94/100)(2500) =
Enthalpy change of liquid = 69,272 - 31,612 = 37,660 kcal/100 kmol gas. Thus, At = ti —12 = 37,660/18Lm, and the relation between Lm/Gm and the liquidphase temperature rise is
A t, °C
