Oxygen content in contaminated nitrogen gas
Thread Content
What impact does an oxygen content in the contaminated nitrogen gas higher than 21% have on the molecular sieve during regeneration?
How can the oxygen content be so high in polluted nitrogen? When the oxygen content in the contaminated nitrogen is 21%, isn’t it the same as using air for regeneration? Refer to how regeneration is carried out originally when there is no nitrogen contamination in the driving process.
It is merely a control parameter; once distillation is established, the oxygen content in the nitrogen stream entering the upper column will not exceed this value~~
When the air separation system is started up, air is used for molecular sieve regeneration; at what point can it be switched to contaminated nitrogen? Why is it required that the oxygen content in the contaminated nitrogen be less than 21% at the time of this switch?
This question is a bit weird:lol:lol
It shouldn’t have much of an impact; the oxygen content in the nitrogen gas produced by single-stage distillation is above 21%
Yes, the oxygen content in the regeneration waste gas from nitrogen generators in many processes is above 30%, and it is generally within the safe range~~
There are requirements regarding the content; it’s probably an electric heater. Another question: what should the levels of nitrogen and oxygen contaminants be during actual operation? (Produced in the lower column under pure nitrogen; only polluted nitrogen is produced in the upper column)
Is it a nitrogen production unit? ~~In single-tower nitrogen production, the content of impurity nitrogen and oxygen may be around 30%~~
The question itself is a bit problematic; it seems to be of a low level. The oxygen content in air is 20.95%, nitrogen accounts for 78.**, and argon makes up 0.932%. It’s clear that this refers to air regeneration. Also, do you want to discuss the dangers associated with high oxygen levels, or are you asking about any issues related to the regeneration process when oxygen levels are high? ? ? The first one has no problem with the purifier; the second one also has no problem.....
It mainly depends on the requirements of the heater; as long as the oxygen content requirement is met during operation of the heater, there will be no problems.
