Amine Regenerator vertical thermosyphon reboiler not flowing properly
Amine Regenerator vertical thermosyphon reboiler not flowing properly
(OP)
We have a thermosyphon reboiler on our amine regenerator that has not been flowing properly since turn around. The bottom sump of the regenerator has a auxiliary baffle and a preferential baffle. In fig 19-37 of the GPSA manual, it is baffle orientation b. We think it might be pluggage, but we can't conclusively verify that. I was wondering if anyone had any experience with this problem, any ideas how to conclusively verify pluggage, or any other potential causes?
Thanks
Thanks

fyi, which edition of gpsa manual is applicable? the 12th edition has fig 19-37 as the design parameters for top feed nozzles. using fig 19-42 does have the various configurations for bottom sumps.

A bit more on the symptoms might be nice as a "flow problem" is pretty non-specific. Opening up the system is likely to be disappointing, I have several times had this come up with nothing useful found inside. On the otherhand shooting some steam (or N2, steam is nice for an aqueous system) just long enough into the reboiler to intitate the thermosyphon, opening equalization between the bottoms compartments, closing the inlet butterfly valve (if you have one) and boiling down the reboiler then opening it, or other kicks to the system have mysteriously started the thermosyphon with the root cause remaining unexplained.

Thanks for all the advice. I will keep ya'll posted and if any body else has any more useful advice I am all ears.

When you say tower capacity is down, is this due to higher bottoms temperature limiting the reboiler, or is there something else?
