Revamping the top section of the water quench tower in an olefins plant provided a 74% reduction in pressure drop. First stage compression ratio was reduced from 2.21 to 2.02. An additional modification of the lower section of such a column with tower packing reduced the heat rejected to the cooling water by 35% with no increase in pressure drop.
