Mass transfer in ternary distillation with sieve tray column

An experimental study on separation performance of a sieve tray column in t ernary distillation is made under total reflux conditions with different tr ay specifications. The effects of operation conditions, tray specifications , and feed concentration on the clear liquid height and mass transfer rate are studied. The dimensionless volumetric vapor phase diffusion flux is cor related with the free area and Reynolds number. Simulation of separation pe rformance of tray column was carried out using the proposed correlations fo r heat and mass transfer rates and clear liquid height. Predicted values of concentration agree with the experimental data of the present study and so me previous works.
