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

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

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

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 liquid at sub-zero temperature at very high pressure upto 200 kg/cm²

Process Equipment and Plant Design
In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement

Results in higher shell side pressure drop

Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient

Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid

Can accomodate less number of tubes for a given shell diameter
