摘要
The invention comprises a downflow shell and tube condenser, especially useful for cryogenic rectification, which includes a shell having an upper tube sheet and a lower tube sheet, the shell extending above the upper tube sheet to create a first reservoir. A plurality of heat transfer tubes extend between the upper tube sheet and the lower tube sheet and also pass through the lower tube sheet. Cold liquid entering the heat transfer tubes flows down through the tubes and causes a condensation of vapor that is in contact therewith within the shell. The cold liquid is at least partially vaporized and exits from the lowermost ends of the heat transfer tubes.
