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

hehehe
You didn't specify inhaled or exhaled air 😂
Such a short crisp and highly informative video. Keep up the good work 😊
Thanks a lot 😊

i have a exam on this and my teacher just couldn’t teach me so thank you for explaining
You are most welcome!
Very nicely explained thanks
Thank you so much.It’s very helpful.I need it.💪🙏🏻👍
Glad it was helpful! 😊
Thankyou. All you did on cryogenics basis
It helped me to a lot ❤
Wonderful! Glad it helped!
I cleared my doubt , thank you.
You are welcome!
I can understand when I Watch this video
Thank you sir for the explanation
I liked it very much 👍👍
You are most welcome!
Tomorrow is my exam and because of you I’m sure I will get great grades
Happy to hear that 🙂 Best of luck!
really good video, just one question if you can help understand. what happened to the 0.04% of hydrogen?
its comes out of the system through non condensable gases vent with other non condensable gases
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.

Krokillious hmmm ryt
thank you !! it was very helpful
Glad to hear that!
Thank you so much I need this for my seminar 🙏🙏
You’re welcome 😊
Argon gas is also used in welding! That's why I know about it!
Who asked?
Great video. When I saw the part about blue argon lasers, I was reminded that I don't know exactly what a laser is even.
It helped me to complete my project thanks a lot sir
Great 👍 You are most welcome!
Very well explained!
Thank you
No problem!
Thank u very much. Such a difficult method was understood very easily.
Nice understandable video.thanks
Glad you liked it!
@@fuseschool yes it's gud
Argon is used for GMAW or MIG welding
Can u pliz explain on the separation and isolation of neon from liquid air
You make good videos ...how about some on space or interesting things on physics 😁
Check out our astrophysics playlist: th-cam.com/play/PLW0gavSzhMlRCrWixI5tKbPfDbSkVuaO-.html
I have a question please , does silica glass resist cryogenic temperatures?
Thanks so much.This was helpful
Thank you too!

Really useful video thank you
great video
god bless you brother
Very useful
Mast...
its really help me
great😍
Thanks
No problem
Thank u sooooo much💜💜
No problem!
Why don't the gases produce an azeotrope?
Awesome
Right, at what pressure?
Thanks😢
Why could the collection not occur when the gasses condense during cooling?
I thought this video will teach to make or extract nitrogen to be used for organic farming :)

Didn't expect a dr stone watcher here
Why not use electrolysis of water? To produce oxygen? That freezer at 179 degrees require huge energy and safety issue.
Ok ,how the air is gathered please anyone explain it
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????????????????????
Nitrogen boils off first because it has the lowest boiling point but why is it collected at the top and not any other part?
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.
and liquid oxygen is a biological solvent altough not easy to handle (extreme fire hazard)
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
Thnx mAn
No problem
can anyone tell me why the CO2 is not collected ? while it is removed
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
Weird they mentioned oxygen for cutting and welding but not Argon as shielding gas for welding
Why is carbon removed from steel, isint steel a carbon iron alloy?
Because it makes it brittle
It isnt fully removed as well
can I separate co2 by this process .any one informed pls
is there any other ways to get N2 and Ar ?
It has not much information about fractional distillation
Can someone tell what is the state of CO2 when removed?
Aritro Ghosh solid
Aritro Ghosh solid
in this process CO2 is removed in pre purification unit so it is in gas form
Its in ice form
Solid. In fact, it's called "dry ice" because CO2 can't exist as a liquid at normal ambient pressure.
cooling at -200 degree is costly
Can anyone summaries this
#NitrogenRejectionUnit
same question
Anyone from my school to see this comment hi it’s Elias
ok
menos mal que hay subtitulos xD
Hallo!
Hi!
Anyone else come here from the Webnovel "release that witch"?
Чида
Yo are you Donald Trump? 1:56
Ahmed Shamy ya ya correct i also thougt it
what happened to the 0.04% of hydrogen?
So I can't really do this at home
Oxygen membrane
Кто из 7-а?)
Или хотя бы из 23 школы?)
