The influence of incomplete contact between gas and liquid phases in the packed column caused by incomplete sprinkling of the bed was described in the paper. The incomplete sprinkling was approached in two ways: part of gas was not in contact with the liquid along the entire column (gas shunting); part of gas was not in contact with the liquid only on certain height of the packing, above which there was a perfect mixing of gas. The influence of incomplete contact between the phases was determined on the basis of isothermal and isobaric binary absorption of dilute solutions in the packed column filled with Raschig rings. Results obtained indicate a substantial increase of absorption ratio in the column with gas shunting. The column was divided into layers.
