HTRI, modeling of an thermosyphon reboiler

[Nik Lebedev]

Hi everyone, i'm new member of this community and i'm happy to join it. So, i have a very difficult question for me with a modeling of an thermosyphon reboiler in HTRI Xchanger Suite. I working at real project of an involvement strait run gasoline to a hydrocracking fractionation section and at first stage of the project i should to model one of the columns which has an thermosyphon reboiler TEMA type AJ12S. It has an one inlet nozzle and two outlet nozzles, there are two pipes connected to these nozzles which connected thru tee to one pipe connected to the column. The scheme and screenshots are included in attachment. So, here is a question, how i should specified in HTRI in detailed piping the two pipes from nozzles-->tee--->pipe to the column if in section "Piping--->Outlet" i have space only for one pipe. I dont know how to tell HTRI that i have two pipes connected to these nozzles which connected thru tee to one pipe connected to the column. Please help me to solve this problem.
P.S Sorry for mistakes, i'm not a native speaker.

Are you trying to set up the entire piping run from the column, through the thermosyphon reboiler, and the 2 phase line return back to the column all on HTRI ?

If HTRI cannot configure the exit piping from these 2 nozzles on the J shell, and do the entire hydraulics for you, that may not be too much of a problem. You could do the piping line hydraulics for the single phase feed to the reboiler and the 2 phase line return ( including this collection manifold on the J shell) separately on some other program, and let HTRI do the thermohydraulics on the reboiler only.

By the way, the simplified sketch here indicates this is a once through thermosyphon reboiler. Check that this is actually the case by looking at the weir arrangement in the bottoms compartment of this column.
