The application of disc and doughnut extraction columns has been increased in different industries due to their advantages. The column conditions affect the operating streams, and the droplet diameter is an important parameter that changes with the pulse and non-pulse conditions in these columns. The performance of the column with the water-toluene system showed that under non-pulse conditions, the dispersed phase velocity affects the droplet sizes inside the column. The decrease in droplet size occurs with the increment in the dispersed phase velocity in non-pulse conditions. But continuous phase velocity does not affect the drop sizes. In pulsed conditions, the amplitude of variations in different pulses is the most critical factor in the type of regime and droplet size.
