ABSTRACT:
A vent condenser that includes an inner tube, an outer shell mounted on and surrounding the inner tube, a middle shell having an annular body and a closed upper end mounted with the body thereof radially spaced between the inner tube and the outer shell, and a helical heat exchange tube mounted in the space between the inner tube and the middle shell in engagement with the body of the middle shell and with the inner tube. A helical channel is formed between the middle shell, the inner tube, and spaced convolutions of the helical tube. Cooling fluid is directed through the helical tube. Discharge from the deaerator vent passes up the inner tube to return along the helical channel to be cooled in indirect heat exchange relation with the cooling fluid in the helical tube to condense water therefrom and to separate the water from noncondensable gases. The noncondensable gases are directed through the space between the middle shell and the outer shell to reheat the noncondensable gases to a sufficient temperature that no substantial plume is formed when the noncondensable gases are discharged through the discharge fitting.
