Equation 24.3 is useful for estimating the losses of compounds by gas stripping. Indeed Gy, where G is the molar gas flow rate, gives the molar loss rate of a given compound in the environment, solvent included.

Ct = total concentration, kmol/m = /Oi/molecular weight solvent, Gm = molar gas flow-rate per unit cross-sectional area, kmol/m s, Lm = molar liquid flow-rate per unit cross-sectional area, kmol/m s. 

Assuming only D evaporates (see the CD-ROM for the situation when this is not the case) the total molar gas flow rate is the inert gas molar flow rate plus the molar flow rate of the evaporating species, in this case species D, is... 

The corresponding variations of partial pressures were expressed taking into account the specific surface area of the catalyst (A=40 mVg), 0 maximal surface concentration (N°, taken as 10 m ), mass of the catalyst sample (m), molar gas flow rate (D) and the total pressure... 

The influence of temperature nonuniformity between different channels was also studied [9]. In this case the channel diameter and the amount of catalyst per channel were assumed to be equal in all channels, but the temperature was not the same in different channels. The temperature influences both the reaction rate and the molar gas flow rate (and therefore the pressure drop). The temperature nonuniformity has a much larger influence on the reactor conversion than the channel diameter. The influence of temperature deviations on the conversion is a function of the activation energy of the reaction ( ), which is expressed via the parameter y = Ea/RT assuming that the reaction rate coefficient is proportional to exp[-y(f/Tf)]. Figure 9.1b shows the influence of the parameter Y on the reactor conversion. The influence of the temperature increases with an increase in the parameter y, which means for reactions with a high activation energy and/or a low reaction temperature. 

The majority of experimental results on bubble columns was obtained from conditions at which the applied concentrations of the transfer components are kept low. Hence the molar gas flow rate can be assumed as sufficiently constant. From table 1 it can be discerned that in this study the mole flow rate of the gas phase varies considerably. Therefore all fluiddynamic properties reveal marked local dependencies. From the measured local gas hold up the concentration profiles and the bubble size distributions axial profiles of the in-...

For a crossflow gas permeator and a binary system, adopt the Naylor-Backer approach and the starting equation (7.2.10). Define and x 2 as the molar gas flow rate and mole fraction of species A at any location in the feed side of the permeator let the values of and x 2 at the permeator exit be and x j. Develop a relation somewhat similar to the result (7.2.12) relating Wa to IV as a function of xa2, a2 rid o ab< where the more permeable species is A in the binary mixture of species A and B.
