Truly thank you for making this video, it was super clear and easy to understand. I have been looking at this topic for a few days now and its been complicated understanding the tracers. You just made this super easy to understand within just 7 minutes. Thank you. Please make more videos of this sort.

[@dheynetelles5956]

The best explanation I've seen so far. Great!

[@southpaw8168]

best video on internet explaining plug flow process and completely mixed flow process. thank you so much.

[@Gojo_Satorou274]

Lovely explanation. Would appreciate more videos of this sort.

Thanks a lot. Unfortunately the preparation of this type of video is very time-consuming... we produce only a few.

[@Gojo_Satorou274]

I get it Ma'am. Each video made in this format would be a great resource for ChE students.

[@jesussamano8573]

Thank you for this explanation, it helped me a lot for these times of online classes. .

that was an amazing 7 mins video to watch! thank you

Reconnecting with old memories decades ago, trying to fight forgetfulness in my brain. I was a postgraduate student of chemical engineering or Technische Chemie in Germany back then. Thanks for uploading this..i really like it. Grüß aus Hannover.

Super helpful! Thank you.

[@MystericalBeast]

Thank you! concise explanation

Thank you 1

[@tanveershah4974]

can someone help me in designing a pliot plant scale reactor for dehydrogenation of ethanol. would appreciate thnx

We do not provide this type of service.

So what is the conclusion? That Mixing not required ?

[@beautyful6373]

a bit puzzled about "the moleculars in a small section of area are hardly mixed with the molecules just behind them or just in front of them ", is this section of area represents the tracer volume injected inside?why its not mixed? thank you!

[@beautyful6373]

ahh, so the tracer is not mixed in the plug flow reactor, but react with the fluid inside the plug flow reactor when it passed along the tube right :) please correct me if I misunderstand sth, thank you

this section of area represents the tracer volume injected : YES, in the case of impulse injection why its not mixed? This is the very principle of a plug-flow reactor: no axial mixing.

The tracer should not react, it is here only to "follow" the flow. But in normal production (= not during a RTD experiment), the molecules react (but only in the section of the tubular reactor; again no axial mixing). We hope it is now clearer for you...

[@jerlinmary3708]

Is tubular reactor is example for closed system..?

Not at all, it is a continuous reactor.

[@lifeinsequence]

It involves only radial mixing, Right?

Yes

Only if my professor taught like this.

[@zenoil9703]

5 minutes to understands.....the video is 7 minutes long

In French it is 5:55 with the credits ;)
