Large scale air/water experiments have been carried out to observe the effects of variation in gas and liquid loads and packed height on the liquid distribution quality 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). The liquid distribution performance of both packings appeared to be consistently good and, surprisingly, the high capacity version performed better than the conventional packing, but at the expense of a more pronounced wall flow, which however appeared to be less sensitive to high gas loads.
