distillation column, also known as a distillation tower or fractional distillation unit, is a crucial piece of equipment in a refinery. It acts like a giant still, separating the complex mixture of crude oil into its various components based on their different boiling points.
Here's a breakdown of its role:
Function: The column separates crude oil, a mixture of numerous hydrocarbons, into different "fractions" based on their volatility. Lighter components with lower boiling points vaporize and rise up the tower, while heavier components with higher boiling points remain as liquid at the bottom.
Process: Crude oil is first heated to around 700°F (400°C). This hot oil is then injected into the bottom of the column, where it partially vaporizes. As the vapors rise, they encounter a series of trays or packing material. These increase the surface area for interaction between the vapor and a descending stream of liquid called reflux.
Separation: Components with lower boiling points readily evaporate and travel upwards with the rising vapors. As they travel, they encounter cooler liquid descending from the top of the column. This cooler liquid condenses some of the vapor, enriching the vapor in lighter components. This process happens repeatedly on each tray, gradually separating the various fractions.
Products: Lighter fractions like gasoline, diesel, and jet fuel are collected from the top of the column, while heavier components like heating oil and asphalt are collected from the bottom.
The distillation column is the first major step in the refining process. It sets the stage for further processing of these fractions into the various petroleum products we use daily.

Very good sir g
Superb Knowledge about Shut Down and columns.I have More than 35 years Abroad Experience in Same Field.Thanks for your Excellent Teaching Skills.Just For Reminding I Am Watching Your Useful and Valuable Information. Thanks & Regards Sir.
Thanks for your comments. I'm really happy to see your comments, you can share your thoughts for newcomers
Thank you sir for sharing
Thanks for sharing
Sonu bhi mai tho taiyari kar raha hu roj aap ki video ka wait karta hu aap bahut accha se bata rahe hai thanks you
Very well sir🙏🏿🙏🏿
Very very Thanku sonu Bhaiya
1. Column ke Andar kya tools lekar jayenge Boxup karne
2. Sabse pehle koin sa tray Box up karte hai
Sonu bhai packed column k bare me bana o
Thank you
Furnace ki bhi bna dijiye
Thank you so much ❤
Good❤
Furnace ki bhi aesi vedeo bnaao sir or bundle remove waly heat exchanger ki bhi
Sir I'm hydro jetting foreman. But I see your every video. You are make a good video.
Sonu sir hi❤..Aap jobhi video again and again upload karo.. Chalega hum log apke video ko video dekhne se pehle like karte hai. repit video banao chalega bhai ❤😊.sir jara flange and valve gasket k bichmain kitna mm gap hona chahiye playing video banao
Okay
Gud sonu sir Meri duaay apky saat hen
Good explanation 👍
And also make a video for documents controllers
23:00 Sir Man hole and Manway are two different things many people are confused by these terms. At point 2 Open Man hole of Column and then we open manway of trays
Suno Bhai im a document controller, please also discribe the role of document controller in shutdown and explan all main documents.
Sir distillation column se demister pad, tray ko bahar nikalne k liye rope pulley and winch ka use hota hai? Ya fr manually nikalte hai
Inside se platform Tak lane ke liye manually and rope ka use hota h aur platform se ground floor per lane ke liye rope Pulley, winch ya phir crane ka use Kiya jata h as per availability
One column me kitne trh ke tray hote hai ya one type ke tray hota hai or ziyada kis trha hai tray use hota hai
Wo us column ke design per depend karta h but generally apko valve tray or sieve tray mil jata h column me
Suno bhai, torquing force kitny hoti bolt tightening k liy?
Bro torque value depend karta flange size or rating and gaskets ke basis per
Sir can you please make the video on maintenance of rotating equipment
Yes I will
Sir purging ka process wo konsi period me aaega
Pre-shutdown me ye operations ka kaam rhata h isliye include nhi Kiya thanks for your suggestion I'll include next time
Sir Make a video on reactor maintenance procedure
Sure
Sir hydro jetting and hydrotest ka pressure kitna hota hai generally ( heat exchanger, vessel)
Hydro-jetting ka pressure depend karta h ki sludge kaisa deposit h tube me aur vessel me agar normal h to 6000-10000 psi Tak rakhte h but jarurat ke hisab se Kam jayada kar sakte h...aur hydrotest ka pressure equipment ke design pressure ke upar depend karta h yani jitna design pressure hoga usse 1.5 times jayada lete h test pressure
Sir can you tell me, at how many points thickness has to be taken in a column?
Thanks for your comments, I'm not sure about this but I must say it has to be done as per inspection plan.
@@SoNuSiNgHRefinery thanks sir.
Can you make a video of Work permit receiver... petrochemical
Yes sure
don't care about the time....must be clear the topic
