# Pick out the wrong statement pertaining to ‘Horton sphere’ used for the storage of liquid ammonia ?

Direct Answer & Quick Reference

The correct option is **D. Horton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm2**.

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

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

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

D. Horton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm2 **(Correct Answer)**
