Internal of a distillation column Internal of a distillation column Hosein Eghbali (Chemical) (OP) 20 Dec 16 18:33 Hi. Guys. I've attached internal of a distillation column with two passes of liquid in it. Is there anybody have idea what the specified points are? RE: Internal of a distillation column don1980 (Chemical) 21 Dec 16 00:42 Sorry, but I've misplaced my copy of your equipment file. Maybe you could have a look for me. Check those locations on the column internals drawings - that'll save a lot of guesswork. RE: Internal of a distillation column sshep (Chemical) 21 Dec 16 00:52 Hello Hosein, 1- looks like a feed or drawoff nozzle with bolt in parts 2- downcomer bolting bar outside weirs 3- downcomer bolting bar inside weirs 4- (cant see it) arrow points to tray support ring 5- unsure, need to see drawings 6- looks like bolting bars for sloped downcomers 7- unsure, maybe brackets for tray support beam The drawings can be hard to read, but withtudy you will figure it out. Bes wishes, SShep RE: Internal of a distillation column Latexman (Chemical) 21 Dec 16 12:08 It looks somewhat new. I recommend you sit (call a meeting) with your Process Engineer, Design Engineer, and the fabricator's Engineer and review ALL of the documentation package. It would be good to go through the P&ID at this time too for thorough understanding. Good luck, Latexman To a ChE, the glass is always full - 1/2 air and 1/2 water. RE: Internal of a distillation column europipe (Chemical) 21 Dec 16 12:23 Latexman, if the OP is the project engineer he wouldn't ask these questions here. Hosein, what is your meddling with this project? RE: Internal of a distillation column Latexman (Chemical) 21 Dec 16 12:35 europipe, Based on past posts, they appear to me to be process or operations or something like that, thus my advise. Better to be direct though, like your question. Good luck, Latexman To a ChE, the glass is always full - 1/2 air and 1/2 water.
