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

Pick out the wrong statement pertaining to 'Horton sphere' used for the storage of liquid ammonia.

Diameter of Horton sphere is normally 6 to 25 metres and it is supported by 6 to 12 nos. tubular or rolled section column

Horton sphere is used for the storage of gases and volatile liquid at a moderate pressure of 1 to 10 kg/cm²

Horton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm²

Thickness of spherical shell is half that of the cylinderical vessel under same operating pressure condition. Besides, the ratio of surface area to volume is less for sphere than any other shape ; hen
