Dissolved oxygen removal from butadiene

[kamran77]

thread798-197200
We are recovering the butadiene from vent gas and after cryogenic condensation the liquid stream (please find below the composition of this liquid stream) it has some dissolved oxygen and we want to remove it.
(Basis mass fractions)

Acrylonitrile = 0.21
Butadiene = 0.97
Styrene = 0.004
Nitrogen = 0.00047
Oxygen = 0.000330
H2O = 0.004670

Vol. flowrate = 0.78 m3/hr
Mass flowrate = 488 kg/hr

Any help will be much appreciated.

What are you looking for with this? I understand your process is rubber, ABS resin or something like that. Maybe you need an adsorption column for remove the oxygen, but be careful, don´t forget that this stream doesn´t have TBC (inhibitor) anymore and is possible the pop corn or peroxyde formation and a very dangerous condition is possible.
