Numerical Solution of Gas-Liquid Reactor Balances

FIGURE 7.22 (a) Simulated concentration profiles in a gas-liquid tank reactor chlorination of p-cresol to monochloro- and dichloro-p-cresol. The concentration is given as a function of the reactor volume, (b) Concentrations in the liquid film at the reactor volume Vr = 0.04 m.  

A requirement for modeling gas-liquid reactors is that the gas and liquid diffusion coefficients and mass transfer coefficients are known. For an estimation of the diffusion coefficients in the gas and liquid phases, see Appendices 4 and 6, respectively. Estimation of mass transfer coefficients is considered in Appendices 5 and 7, and methods for calculating the gas solubilities are discussed in Appendix 8.
