Flooding in distillation Column | Symptoms of flooding | What will happen when we increase reflux

[@im_godspeed]

I'm working in the oil industry for the past 7 years and still I get to learn a lot from you brother. Thanks for making these informative videos

[@brandonking4918]

Great work sir!!! As always Conceptually explained. I have been following your work since my college. Currently I am working as a trainee in a chemical industry. My request to you sir is to come up with distillation column operation videos. Common problems and troubleshooting.

[@faisaljummal8101]

Very nice. 2 times me 90% samjha mai

16:14 ❓How temperature is decreasing when we see the tie line in Txy plot 🔴 Xa (Xa is MVC composition in liq) decreasing >> Temp of Tie line increased (Txy diagram se) 🔴 Top pressure not changing so Txy diagram also not changing

[@yashchoukse2874]

Please explain the hot vapour by pass method of pressure control.It would be very helpful.

[@RahulMaurya-vt9hk]

Well cleared concept❤ . I have done apprenticeship iocl panipat. So i can understanding Easley

[@srinivasanvenkatasubramani1670]

Very well explained. Thanks. About the spray nozzles, you may consider to add the following: In large columns, liquid is sprayed by nozzles through pipes arranged like a spider. Liquid forms a cone shape while flowing down. There will be many spray cones. These cones must be overlapping with each other, so that the vapors coming from below must pass through the liquid spray. If there are no overlaps, the hot vapors can have free ride and can cause coking. At the periphery of the column , overlapping of spray may not be possible. Such locations are called Dead Zones. The percentage of Dead Zones is kept minimum. This aspect is considered while designing.

Thank you sir for valuable information!

Dear sir Thanks for the video sir you are doing a fabulous job. #Thanks for your priceless work.

Very clear concept

Excellent to the power Excellent

[@sunilsahu2525]

Good explanation

[@gurudayal3438]

Hello Good evening sir. One q, When increase the reflux ratio in distillation colunm then, 1) increase mass transfer, 2) increase heat transfer , 3) increase vapour pressure. 4) 1&2 boths . .

[@SandeepAcademy9]

1&2 both...Go through this video. All concept will be cleared.

[@yashchawade4569]

Sandeep sir tys for such learning vedio on distillation...! Sir, tellme how to calculate column diameter of distillation column? Have u made any specific vedio for design of distillation collumn? So that i can refer it! Plz reply asap🙏🙏

[@aloogobhi4223]

Sir great video can u tell how a control tray is decided for a distillation column and also how does that tray gurantees proper product specification .

[@tvincentj]

thank you sir❤

[@suryaprakashsahu6754]

Very informative video. Thank you so much sir. Can we reduce flooding i.e. maintain column to normal conditions by reducing reflux, condenser and reboiler duty? Also please clear how reflux drum T increases as we increase Reflux?

[@SandeepAcademy9]

Depending upon condition if by increasing reflux fractionation getting worse.....then certainly reduce reflux to avoid flooding. However if Weeping/Dumping was taking place, in that case increasing reflux would be helpful. Overhead temp would increase if reboiler duty is fixed or if reboiler duty has been increased but top temp remain same. For overheard temperature think of LMTD. Delta T of both side.....if heat duty of condenser has been increased in that case LMTD must increase. Now condenser U/S side delta T has been increased (if top temp same) it means condenser d/S delta T sud decrease and hence overhead drum temp will increase. WRITE equation then only you will understand.

Sir design of shell and tube heat exchanger ka video banav ❤️

[@shishirendra]

Reflux ratio par video banaye

[@nkverma8915]

Sir coloum me jo down cumer ki hight hoti h o column ke sabhi trays ke liye same height hoti h ya different hoti h? Only down cumer me liquid ki height ke karan pressure change hoti h sir.

[@dk.who0]

how to identify if flooding is downcomer backup flooding? or entrainment flooding?

[@onel276]

Nice sir, Can anyone suggest me books to learn more about distilation column apart from lieberman

[@souravkumar2522]

Sir, how to calculate steam requirements in reboiler ??

Thank u sir

If column pressure suddenly start decreasing then what will happen sir?

[@najmulhassanofficial3104]

Thnks appreciated ..

[@SandeepAcademy9]

Always welcome

[@boraddivyesh3872]

Sir why reflux drum's temprature increased while we are increasing reflux??

[@adilsaifitech838]

Sir, valve series me safety valve per bhi video upload kijiye please.

[@SandeepAcademy9]

ab aur nahi bhi....next time ....
