C3 hydrogenation reactor run lengths
C3 hydrogenation reactor run lengths
(OP)
in our company we have a problem in the C3 hydrogenation reactor run lengths.
the operation of the reactor is poor, run lengths of 20 days being experienced instead of the design period of 120 days.
Thanks for your participation.

they told us that the problem may be from the catalyst (G-55 B).
yes, it is for selective hydrogenation of methyl acetylene and propadiene in the propylene stream.
we had contacted the catalyst vendor to investigate this problem. the vendor suspected poisons which would gradually reduce the activity of the catalyst. with permanent poisons, it is not possible to regenerate the catalyst in order to fully restore catalyst activity. the vendor had therefore proposed a sacrificial bed layer to be installed on top of the catalyst bed. this has not been implemented.
if any one know any reference book related to this subject please give me it's name or link.
thank you all

Alternatives suggested on the net article indicate that extractive distillation with DMF ( dimethly formamide or some other high dipole moment / polar organic solvent) to remove MA and PD are also possible, but in a running plant, the modifications required may be impractical.

I will search about it
