Tower Internals
- Flashing feed gallery is a feed device to accommodate mixed liquid/vapor or flashing feeds. The 2 phase liquid is fed to the column through a nozzle tangentially against the tower wall. The residence time allowing the vapor phase to disengage from the liquid and the clear liquid then flows directly to a distributor.
- Liquid only feed pipe is used when liquid is fed from outside the column for distributors. The incoming flow must contain less than 1% vapor by volume. A perforated pipe composed by a main header and secondary flanged branches is typically used for liquid inlets.
- Cartridge trays are typically used in flanged columns where the tower diameter is so low and no manhole is used. Generally, for columns with diameters less than 900 mm any of tray products can be manufactured in cartridge-style construction. This scheme can only provide up to 5 trays per cartridge […]
