How should the submersion tube height be set when calculating vertical thermosyphon reboilers using HTRI?
Thread Content
Using HTRI v7.2 to calculate a vertical thermosyphon reboiler: the shell side has a heat flow, with steam undergoing condensation; the tube side has a cold flow, with liquid light hydrocarbons boiling upon heating. When the heat transfer capacity decreases, the heat transfer area is reduced by raising the level of the condensate water in the shell side – thereby submerging a certain length of the heat exchange tubes. However, no option to set the height at which the tubes are submerged was found in the software. I’m wondering if anyone knows how to do this?
That is generally used to handle the load of the tower top condenser, controlling the load of the entire tower. For this, you generally use the valve on the steam feed pipe to control it
