Sieve plate design perforated area

Since the behavior of packed columns [2,3,4, 5] and bubble cap columns [6] has been previously reported, this research at the National Bureau of Standards was primarily concerned with the characteristics of perforated or sieve plate columns. Such parameters as plate spacing, plate geometry, maximum allowable vapor velocity, weir height and downcomer area were investigated, and the results of these investigations were applied to the design of a pilot plant column.
