Process Equipment and Plant Design
Smaller sized packings are generally dumped to the packed columns, and the large ones of size greater than __________ mm are stacked individually, which provides better control over bed porosity and offers lower gas pressure drop.
Providing a higher skirt clearance or a higher weir
All of these
Using split flow, radial flow or cascade flow for column diameter large than 4 ft
Decreasing the number of rows of caps through which the liquid flows or by decreasing the velocity of liquid flow past the caps or by reducing the distance along the tray through which the liquid must
