Extraction Of Oxygen & Nitrogen From Liquid Air | Reactions | Chemistry | FuseSchool

[@hopydaddy]

Very clear and informative. Gives more concrete and detailed information than some of the other lengthy videos with vague explanations.

[@ufcfanatic8178]

Such a short crisp and highly informative video. Keep up the good work 😊

[@fuseschool]

Thanks a lot 😊

[@sirfanatic]

thank you so much, i asked my chemistry teacher how would i be able to extract o2 from the air we breathe. she looked at me like i was crazy.

[@hypeboy306]

sirfanatic 😂😂😂

[@GRBtutorials]

Well, you kinda need to be... pure oxygen makes many things that usually aren't flammable flammable, and flammable things are even more flammable. And liquid oxygen is even more dangerous, because it's concentrated in addition to being at a very low temperature! Not saying it's a bad thing to be crazy, of course, we're all a bit crazy. Though there's another way of getting oxygen from air, that needs less energy and is less dangerous because you don't have to handle liquid oxygen: pressure swing adsorption. Basically, you pass air through molecular sieves, which adsorb (yes, adsorb with "d", the molecules get stuck in the surface of their pores) the nitrogen leaving an oxygen-enriched atmosphere.

Argon gas is also used in welding! That's why I know about it!

[@mahir7500]

Who asked?

[@OS-Insights]

really good video, just one question if you can help understand. what happened to the 0.04% of hydrogen?

[@junaidahmed608]

its comes out of the system through non condensable gases vent with other non condensable gases

[@Gloin79]

I know this is 2 years old but for others with the same question: the water is removed after dust filtration. During inital cooling of the air, the water condenses into liquid and is drained away. This is very important since the water would freeze into a solid and cause damage to equipment.

[@GRBtutorials]

That's not hydrogen, but CO2, and it solidifies at -79 ºC and is removed: 1:03. And if it was hydrogen, it would just escape as a gas because the boiling point of hydrogen is -253 ºC, way lower than the -200 ºC air is cooled to.

[@deankay4434]

75% of my welding shield gas is nitrogen. 25% CO2 mixed together with the nitrogen, it’s flow amount is controlled to push the oxygen away from the electric arc that welds two pieces of mild steel together. Argon is used with a TIG welder and used with stainless steel in the food industry to keep things clean. Bacteria will not grow on copper and salt. Salt has been harvested from sea water for thousands of years. Allow for water to evaporate, a red algae flourishes. Used to preserved food like salt cod, jerky and other meat proteins. The only an essential element in the human body to help the brain conduct electrical between nerves and in the brain, but adds flavor to food. Try a small amount on store bought ice cream someday. The favorite of mine is pink Himalayan salt is my favorite. Ironically, our blood and sea are both about 3% salt.

I have a question please , does silica glass resist cryogenic temperatures?

[@Krokillious]

The video makes it look like the fractional distillation is a batch process? While in reality it is a continues process? Keep up the good work! Love the videos from The Fuse School!

Right, at what pressure?

[@Leo8dGreat]

I thought this video will teach to make or extract nitrogen to be used for organic farming :)

[@benjaminlarson6168]

Why don't the gases produce an azeotrope?

[@iamarxalan]

Why not use electrolysis of water? To produce oxygen? That freezer at 179 degrees require huge energy and safety issue.

[@brightside6134]

Thnx mAn

[@fuseschool]

No problem

[@sabrinang7330]

but i wanna ask that if it processes in the reality ? because the difference is only 3 degree celcius , such little is it really work????????????????????

[@colinyoung3685]

Why could the collection not occur when the gasses condense during cooling?

[@luisfcayo]

I was watching this because I was watching Dr. Stone and they were trying to figure out how to prevent a filament from burning when they were recreating the light bulb, so I thought how do you obtain inert gasses.

[@silverreaps6803]

Didn't expect a dr stone watcher here

[@somalilionupdy8834]

How about when air is filtered the (dust free air ) passes through sodium hydroxide solution so that carbon (IV) oxide is absorbed and then CO2 free air is cooled -25°C to obtain air free of water vapour then u go on with the fractional distillation

[@junaidahmed608]

description might be wrong dear first of all air is not cooled upto -200C, and -183C oxygen gas convert into liquid, -186 C argon gas to liquid argon while nitrogen gas becomes liquid at -196 C

[@x.x206]

Nitrogen boils off first because it has the lowest boiling point but why is it collected at the top and not any other part?

[@alamgirgazi1540]

can I separate co2 by this process .any one informed pls

[@jacobnoyons4276]

youre forgetting a mayor fact. argon IS inert and if you are working with anything that will easyly oxidize (aluminium near melting or fine aluminium powder for example) nitrogen will not protect the metal argon will, argon is a noble gas. argon has a lot of uses.

[@jacobnoyons4276]

and liquid oxygen is a biological solvent altough not easy to handle (extreme fire hazard)

[@laipo1175]

can anyone tell me why the CO2 is not collected ? while it is removed

[@junaidahmed608]

simple when co2 reaches the MHX co2 becomes solid and block whole passage dueto which whole process disturbed, compressor might go into surge, turbine seized etc

[@dpkbharadwaj12]

cooling at -200 degree is costly

[@trezza181]

Weird they mentioned oxygen for cutting and welding but not Argon as shielding gas for welding

[@MolotovWithLux]

#NitrogenRejectionUnit

[@brandon_goes_backpacking]

Why is carbon removed from steel, isint steel a carbon iron alloy?

[@x.x206]

Because it makes it brittle It isnt fully removed as well

[@monserret.7570]

Can anyone summaries this

[@medsahli1994]

is there any other ways to get N2 and Ar ?

Hallo!

[@fuseschool]

Hi!

[@aritro10]

Can someone tell what is the state of CO2 when removed?

[@yukcheongtang3152]

Aritro Ghosh solid

[@brightside6134]

Aritro Ghosh solid

[@junaidahmed608]

in this process CO2 is removed in pre purification unit so it is in gas form

[@sheetalgrover8810]

Its in ice form

[@GRBtutorials]

Solid. In fact, it's called "dry ice" because CO2 can't exist as a liquid at normal ambient pressure.
