FILM TUBULAR HEAT AND MASS EXCHANGER Russian patent published in 2023 - IPC B01D3/28 

FIELD: heat and mass transfer.

SUBSTANCE: film heat-and-mass transfer apparatus contains a vertical housing, upper and lower chambers, upper and lower tube sheets, heat exchange pipes, as well as fittings for inlet and outlet of the heating medium connected to the body, fittings for input of raw materials and output of the liquid phase connected to the chambers at opposite ends of the apparatus, a gas phase outlet fitting connected to the upper chamber of the apparatus. Horizontal baffles are installed in the annular space. Also, the device contains the upper and lower separation volumes of the pipe space, while the upper one is equipped with a mist eliminator, and the lower one, ensuring the separation of the two-phase liquid into an aqueous layer and a hydrocarbon layer, is equipped with a nozzle that provides an increase in the path of the two-phase liquid from the place of draining from the heat exchange pipes to the outlet fittings for removal of the water layer and the hydrocarbon layer, and level gauges for the water layer and for the hydrocarbon layer. The pipes in the pipe space are a multi-pass section. An additional vertical partition is installed in the annular space.

EFFECT: increased efficiency of heat transfer in the apparatus.
