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

A. More
B. Same
C. Less
D. Twice

A. 1000
B. 3000
C. 5000
D. 10000

A. Triangular pitch
B. Square pitch
C. Diagonal square pitch
D. Heat transfer rate is independent of tube arrangement

A. It reduces heat transfer area
B. More thinner tubes can be used
C. Pressure drop is reduced
D. It makes condenser compact

A. Reducing scale deposition
B. Increasing pressure drop
C. Fixing the tubes
D. Creating turbulence

A. Sorel-Lewis method
B. McCabe-Thiele’s method
C. Ponchon-Savarit method
D. None of these

A. An increase in liquid viscosity
B. An increase in relative volatility for rectification columns
C. Decrease in gas solubility for absorbers
D. All A., B. and C.

A. 4-8
B. 17-34
C. 52-68
D. 88-105

A. A vapor phase reactor
