» Training case study: Vibration concern in U-tube reactor effluent cooler—beyond the initial screening

In this case study, a TEMA DEU heat exchanger design must cool high pressure reactor effluent from 180 °C to 40 °C. The corrosive reactor gas is assigned to the tube side, with cooling water on the shell side. The cooling water inlet nozzle is located at the U-bend. A circular impingement plate is specified in accordance with TEMA ρV 2 guidelines. The bundle has parallel-cut double-segmental baffles to meet the shellside pressure drop limit, and sealing devices are specified in the baffle overlap regions to mitigate flow bypassing.
