Question
TCE is only sparingly soluble in water, and the Henry's law
constant for TCE in liquid water is 9.97 atm/(kg mol/m³). The
molecular weight for TCE is 131.4 g/g mol. Assume that the air
stream serves as an infinite sink for TCE transfer, so that the
partial pressure of TCE in the gas bubble is essentially zero.
Furthermore, assume that the interphase mass transfer process is
liquid film controlling. The mass diffusivity of TCE in water at
293 K is DAB = 8.9 x 10-10 m²/s.
a. Develop a well-mixed, unsteady state material balance
model for dissolved TCE in the liquid phase of the trench.
b. Determine the required time to reduce the dissolved TCE
concentration from 50 to 0.005 g TCE/m³.
