EG vapour condensing
Condensing ethylene glycol vapour drawn off the polycondensation train under vacuum.
Recommended type
Plate & Shell Heat Exchanger
Condensing under vacuum makes pressure drop on the vapour side the governing number, not the heat transfer area. A spiral gives one wide continuous channel and takes the oligomer that comes over with the glycol; plate & shell is the choice where the vacuum vessel has to be code stamped.
