This paper presents the results of an experimental study carried out using large scale equipment to ob-serve the effect of geometry on gas distribution properties of a high capacity corrugated sheet structured packing (Montz-pak B1-250M) and to compare it with that of its conventional counterpart (Montz-pak B1-250). Although the high capacity packing exhibits a significantly lower overall pressure drop, the gas distribution performance is similar to that of the conventional packing, and in both cases consistently good one.
