Continuity Equations for Tank Reactors

Since the gas phase is in BMF, the continuity equation corresponding to 24.4-1, and based on the entire vessel of volume V = Ach = (irlPlfyh, is 

Since the liquid phase is in BMF, the continuity equation for A in the bulk liquid phase is similar to equation 24.4-15, except that the integration in the second term on the left is unnecessary because both pA and cA in the expression for NA are constant (.Pa = Pa,out and cA = cAj0 J. Thus, we have 

The overall material balance around the tank is again given by equation 24.4-9
