High pressure fluid in a shell and tube heat exchanger should preferably be routed through the

Shell side, if the flow is counter-current and tube side if the flow is co-current

Shell side for large overall heat transfer co-efficient

Tubes to avoid the expansion of high pressure shell construction

Shell side for smaller total pressure drop

Process Equipment and Plant Design
Pressure drop (Δp) and the superficial gas mass velocity (G) in case of packed absorption tower operating in the preloading range are related as

Δp = G

Δp = 1/G0.6

Δp = G2

Δp = G0.5

Δp = G

Δp = 1/G0.6

Δp = G2

Δp = G0.5
