gas phase reactor
(OP)
in the gas phase hydrogenation reactor, is it possible to recycling the outlet of the reactor to reduce the inlet concentration of MAP (methyl acetylene & propadiene)?!

RE: gas phase reactor
To concentrate these components, it would depend on the location of this reactor in the separation section, which you havent said ( is this reactor still on the bottoms exit from the de ethaniser ?)
RE: gas phase reactor
I searched about the reason of poor run lengths of the C3 hydrogenation reactor, and I find that for Operating safety demands that the significant exotherms experienced in MAPD hydrogenation be tightly controlled. This is commonly achieved by recycling lead bed product in liquid phase two-bed systems in order to limit the MAPD content in fresh feed.
My inquiry, is it work with gas phase system?
thank you
RE: gas phase reactor
Although the temp rise in gas phase would be much higher than that for liquid phase for a given conversion(for obvious reasons), my simple reasoning tells me the same should be possible for gas phase, assuming you have sufficient means for intercooling and with intercooling at shorter bed depths. Would guess overall net bed depth woould be more than in liquid phase in order to enable running at lower temps to allow for bigger control response margin for temperature runaway.
