Source of nitrogen gas for decarburization stripping
Thread Content
As is well known, nitrogen is the best gas to use for decarbonization stripping. But I wonder where everyone gets their nitrogen from, what its pressure and temperature are, and whether it is contaminated nitrogen from air cooling (of course, this nitrogen needs to be dried first)
The pressure used with liquid nitrogen washing is 0.42 MPA, and the temperature is 40°C.
What process? ………………
If there is no liquid nitrogen washing, it is low-pressure nitrogen from air separation. About 4 kilograms, I guess.
Installing an air separation unit just for nitrogen stripping – isn’t that wasteful?
Contaminated nitrogen gas contains oxygen, which will accelerate the corrosion of Tower 3!
