The design of rectification columns is based on the method thetheoretical tray and actual setupof real trays carried out with help various kinetic characteristics, such as efficiency. relation between local integral efficiency a complex function geometric, physicochemical hydrodynamic factors. A theoretical for calculating has not yet been proposed, because setting influence number Empirical co...

Using sie®e-tray air stripping as a means of remo®ing contaminants from surfactant solutions was studied to determine if tray air stripping can be applied successfully to treating surfactant-containing wastewaters and, if so, to de®elop a quantitati®e approach for designing tray air-stripping systems for treating surfactant-containing wastewaters. High-concentration surfactant solutions were pr...

A better understanding of the hydrodynamics related to flooding conditions in distillation columns is required in order to provide optimised designs for new plants and plant retrofits. Current flooding prediction correlations are predominantly based on air/water systems and tend to diverge at high vapour capacities. In this work an experimental setup was designed and constructed to test the hyd...
