Vertical thermosiphon reboiler1. Select vertical shell orientation on Shell panel.2. Select thermosiphon reboiler for reboiler type on Reboiler panel. If you specify required static head on Reboiler panel, Xist iterates to achieve the specified static head. Xist adjusts the cold fluid flow rate and cold outlet fraction vapor to achieve desired static head. This instance is an eception to the rule that Xist always respects specified process conditions. If you do not specify required static head on Reboiler panel, Xist calculates required static head to achieve specified process conditions. !ote that specified inlet pressure for cold fluid is assumed to be at the echan"er inlet unless you specify the pressure at column bottom option on the Reboiler panel. #lways enter echan"er duty on $rocess %onditions panel when you specify static head. If it is not specified, Xist runs in un&nown duty mode when the head is specified, which can si"nificantly increase run time.'. Specify inlet and outlet thermosiphon pipin".(.
