Does air separation produce waste gas?

2008-11-24View Original

Thread Content

As the title suggests, does an air separation unit produce waste gas? It seems not to, but some sources say it does; I’m not sure. Is air considered waste gas as well? Depressed.

There is a small amount of non-condensable gas in the main condensation evaporator of the air separation unit that needs to be vented. Do you mean the exhaust gas to be this small amount of non-condensable gas?

I think it depends on what you want to recover from the waste gases. In the main cooler, inert gases such as krypton and xenon are emitted from time to time; but if you can recover krypton and xenon, then they are no longer considered waste gases. You’ll understand this by looking at the air separation process

Gases that affect the safety of air separation units can all be considered waste gases. Such as hydrocarbons, sulfides. When the levels of these gases in the main coolant exceed the limits, there is a risk of explosion.

There is a small amount of non-condensable gas in the main condensation evaporator of the air separation unit; in addition, the contaminated nitrogen gas used in the regeneration adsorbers, as well as that used in the water cooling tower, is also released – all of this can be considered waste gas!

It’s not useful; the gas emitted by the steam ejector has a temperature at least higher than room temperature – it’s a greenhouse gas.

Oxygen is required; everything else is waste gas; Nitrogen is required; everything else is waste gas ; If oxygen, nitrogen, argon, and krypton are required, the rest are waste gases. Even if it’s useless, I won’t take it; it depends on what you ask for! ! !

It depends on what you need; anything you don’t need can be considered waste!

It depends on how one understands exhaust gas. Air separation units do not produce any new gases (with the exception of the oil vapor generated in the compressor tank), but after separating oxygen and nitrogen, other trace gases present in the air remain and need to be discharged; these gases can also be considered exhaust gas.

Different understandings of the definition of waste are fine; it’s okay to continue discussing despite differing standards.

Theoretically, anything that’s useless to you is considered waste gas, but I think what you mean is the fumes from the unit’s oil station
