Process Equipment and Plant Design
At the following point for a given packing and set of fluids, the pressure drop per metre of packed height, with variation in fluid rates and operating pressure
Remains same
Decreases
May increase or decrease depending upon the solubility of the gas in the liquid
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
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
Baffles are supported independently of the tubes by tie rods and positioned by spacers
Bracket supports are used for horizontal shell, while saddle support is used for vertical shell
