A small question: when sending carbon black exhaust to a combustion furnace, is it economically viable to separate the nitrogen from it?
Thread Content
Assuming that after dehumidification, the exhaust gas composition is CO: 17%, CO2: 1%, H2: 20%, N2: 61%, and H2O: 1%, would separating out the nitrogen and sending the remaining gas to combustion increase economic benefits? Please guide the discussion.
It’s all going to be burned anyway; what’s the use of recovering N2?； If the quantity is large, it would be more useful to recover the CO and H2 from it.
Reply to 2# zhy809078: Nitrogen indeed is useless, but removing it doesn’t it mean creating a higher oxygen level in the boiler, which could help with complete combustion or something like that...
