Heat Transfer
In a gas-liquid shell and tube heat exchanger, the

Gases to be heated/cooled is normally routed through the shell side, because the corrosion caused by the cooling water or steam condensate remain localised to the tubes

Gases under high pressure are routed through the tube side, because high pressure gases are corrosive in nature

Presence of a non-condensible gas decreases the condensing film co-efficient
