Integral Models of Turbulent Micromixing in Processes with Complex Chemical Reactions

Turbulent mixing during an irreversible isothermal competitive–consecutive reaction is considered. The sensitivity of the calculated results to the choice of micromixing model is analyzed. The upper- and lower-bound estimates of the average concentration of the desired product and selectivity are obtained for integral models of micromixing. The initial concentrations of the reactants affect the process characteristics. Simple analytical expressions are derived for the conditions for complete conversion of the initial reactants. Calculations for portionwise adding of the reactants are also performed.
