Liquid gradient over a tray can be minimised by

Providing a higher skirt clearance or a higher weir

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

Using split flow, radial flow or cascade flow for column diameter large than 4 ft

Pick out the wrong statement pertaining to the design of the distillation column.

If sufficient slot area is not provided, the gas may pass through the skirt clearance

Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up

None of these

The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles
