INFLUENCES OF NON-IDEAL FLOW OF LIQUID ON EQUIVALENT NTP IN PACKED COLUMN |
| |
| Abstract: | Based on the study of the microscopic flow mechanism of liquid in packed column, a zone-stooge model is proposed, by which the efficiency of the column is simulated in the non-ideal flow state. The influences of liquid maldistribution and the lateral mixing of gas on the equivalent NTP are shown by the curves calculated. Finally, a method for calculating the efficiency of practical packed column is given. |
