【 摘 要 】

References(22)Cited-By(2)An experimental study on separation performance of a sieve tray column in ternary distillation is made under total reflux conditions with different tray 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 correlated with the free area and Reynolds number. Simulation of separation performance of tray column was carried out using the proposed correlations for heat and mass transfer rates and clear liquid height. Predicted values of concentration agree with the experimental data of the present study and some previous works.
