A SHELL-AND-TUBE HEAT AND MASS TRANSFER DEVICE

摘要

A sheli-and-tube heat and mass transfer device is disclosed which achieves higher heat and mass transfer, requires less heat/mass transfer area, and is light and compact. The device 100 comprises a vertical cylindrical shell 102 and at least one set of helical coils 104 concentrically placed inside the shell 102; wherein the set of helical coils are supported on coil supports 116 which are joined to the shell 102. The heat/mass transfer fluids pass counter-currently such that a vertical falling film is formed.
