Pump around zone is mainly used for heat removal. Since we do not rely on pumparounds to fractionate - but just to remove heat - good vapor- liquid distribution is not critical. On the other hand, Liquid flows in the pump around section are greater than in other section. That's why there may be flooding in pump around section. For these reason a bed of 4 or 5 ft of structured packing is often, then an excellent selection for the pumparound section of tower. The capacity of such a bed potentially has a 30 to 40 percent advantages over trays. Having said this, I have seen many pump around zone which uses tray instead of packing.
Good to see you with your lectures. Good work Sandeep. Your lectures are of worth even for teachers and non-academicians with Chemical engineering background.
Sir I drew the graph of McCabe thiele method and the point of intersection of the stripping, rectifying and feed lines is coming between the 5th and 6th tray. So accordingly I should place the feed inlet between 5th and 6th tray. My question is if I place the inlet somewhere else what will happen?
In packed coulmn!! Agar liquid flowrate inlet mein two side banching kardi jaaye! And on the packing 50% 50% horizontally liquid distribute kardiya jaye toh proboem solve ho jayegi channelling ki??
Sir is that true that in flash zone we are increasing the surface area which ultimately gives rise to a higher rate of evaporation....? 2nd in some books I have seen that there are usage of prv valve for feet in cot line before entering the coloumn why this is not used in modern refineries?
Aj tu ap ny sir bhry mood mai vdio bnyi.kapi khush ty haha MashAllah.. good vdioe.. make a vdio on MTT mood ..furnace mood .. and other different moodes of distillation operation. Start up procedures.. control etc
Hi..can you a video on how absorption endothermic or exothermic with its chemistry.. Can u explain why we are using intercoolers in absorber if absorption is endothermic??
Random Packing has more pressure than Structured/Regular Packing because the flow path in structured packing is defined and structured unlike random Packing
In Haldia refinery i think tray tower used in VDU-I as i read in manual there is 22 trays in column....why not packed bed inspite it is vaccum column or am i wrong?
Sir, Kindly make video series on pumps with complete details like capacity..important selection parameters and its calculations...hydraulics etc..etc..
Sir please make video on effects of reflux ratio on distillation column aur feed ke bare me kuch sir different types of feed hote hai unka value kaise less than one hota hai ya greater than one etc please
Sir pani kyu supply karte hai vapour ke saath contact me aane ke liye? Aapne bataya mass transfer krne ke liye, lekin ye samujh me nahi aaraha hai, thoda practically bataye jaise paani nahi supply karenge to kya hoga

Sir please make vedio on, how to study p&ID diagram, earlier vedio don't have sufficient information. Kindly tell by live example. And alos tell how me select hydrotest limits of Piping / flow line during hydrotest. Earlier vedio on how to study P&ID don't have sufficient information.
That I can't do that. P&ID are confidential and I can not discuss on RUclips. In P&ID videos I have explained enough such that anyone can read P&ID by himself.

Maine kab kaha?....maine to yahi kaha ki most of the column tray column hai....VDU me packed bed hai....pump around zone me kahi kahi packed bed hota hai....kahi kahi tray hota hai....
@@SandeepAcademy9 thank you sir... 😊 Sir pump around ke pass packed bed kyu use hota hai... apne jab pump around explain kiya tha to tray use kaarke explain kiya.... 🤔.

@@saniruddhaan Thank You Sir ! Where are you ?
One of the best videos out there to understand why a column has trays and packings. 🎉🎉
one of the most informative video.
please a lecture about absorption and adsorption topics mostly used in refinery.
Majaa aa gaya
Especially shut down drawbacks of packed column
End of the story : Tray tower zindabaad 😂. Very well explained sir thank you so much 🙏🏻
sir i read by treybal but i didnt got there but now i can even understand every line of that page...thnx
Excellent 👌 and very informative video.
Plz make a video on circulating, external and internal refulx.
Sir I drew the graph of McCabe thiele method and the point of intersection of the stripping, rectifying and feed lines is coming between the 5th and 6th tray. So accordingly I should place the feed inlet between 5th and 6th tray. My question is if I place the inlet somewhere else what will happen?
you have explaine very easy and understandable. thanx for that
In packed coulmn!! Agar liquid flowrate inlet mein two side banching kardi jaaye! And on the packing 50% 50% horizontally liquid distribute kardiya jaye toh proboem solve ho jayegi channelling ki??
VDU me packing used hota he
To fir VDU ka diameter hive hota he?
Sir is that true that in flash zone we are increasing the surface area which ultimately gives rise to a higher rate of evaporation....?
2nd in some books I have seen that there are usage of prv valve for feet in cot line before entering the coloumn why this is not used in modern refineries?
Tyank🎉you sir.proud of youu,
All concepts clear
Tbbe n niche jayega ji 😅😂 maja aa gya gurudev🙏🙏
Really it was amazing and funny.😂nice explanation
Your explanation is very nice ❤
Sir agar feed mera saturated liquid ho to feeding rectifying ya stripping kis m karenge

Thank You Sir very widely covered video and very well compiled also
Please make video on how reflux is added and what are the effects of total reflux minimum reflux and optimum reflux on trays and column overall

Sir ek video pump, blower and compressor pr bnao
Petlyuk distillation column ke bhare me bayaiye. Hamare plant me ye use kiya hai
Hi..can you a video on how absorption endothermic or exothermic with its chemistry..
Can u explain why we are using intercoolers in absorber if absorption is endothermic??
Sir what is vapour horn in vacuum distillation column??
Which has more pressure drop, random packing or regular packing and why? Can you please elaborate something, because I'm very confused in that...
Random Packing has more pressure than Structured/Regular Packing because the flow path in structured packing is defined and structured unlike random Packing
In Haldia refinery i think tray tower used in VDU-I as i read in manual there is 22 trays in column....why not packed bed inspite it is vaccum column or am i wrong?
In stripping section there would be tray which is below the Feed inlet.
Air separation distillation column design parameters par video banaiye
sir bhut interesting way me aap explain kr dete hain....😂😂😂
Thanks !
Which types of packing used in Atmospheric tower, vacuum tower, Absorption tower.
Tray tower be like :- haar ke jitne wale ko bazigar kehte hai 🤣🤣😂😂
Packed Tower be like: "kia karu main? apna Job chorh du?"😂

Thank you Sir 🙏.
bhaiya why we use packed tower for absorption and tray tower for distillation ?
Its not always true...I have seen many absorption tower which is tray tower.
@@SandeepAcademy9 ok bhaiya
Thanku so much sir
much needed...
Great sir
Pump around ko kyo ham mainly return krte hai
Pump around ka main kam heat ko remove karna hota . As used pump around reflux.
