Greater cost for the condenser coolant

Greater cost for the reboiler heat supply

Lower fixed charges for the column

All of these

Clearance between shell & baffles and between tube & baffles should be minimum to avoid by-passing of the fluid, but it should be enough to permit the removal of tube bundle

Tie rods are fixed at one end in the tube sheet by making blind holes and the minimum number of tie rods is 4 with at least 10 mm diameter

Bracket supports are used for horizontal shell, while saddle support is used for vertical shell

Baffles are supported independently of the tubes by tie rods and positioned by spacers

The most suitable for thick vertical vessel

Same as bracket support

Provided usually for vessels of much smaller height than skirt supported vessels
