Thank you for the video! Helped me a lot! Keep going
Very usefull... thank you sir..👌👏🏼
Nicely and simple explaination. thanks
Very usefull thank you..
For exam i was studying this for 2 days and saw this video 10 min before exam
Now thinking why do i go to classroom 🤔🤔
Nicely explained
Good information in video, but pls try to speak much more slowly and try to be much more calm, you speak very anxious and worried and fast. Calm down. Slowly slowly. Thank you. Good information
Thank you for the feedback. Noted!
Very usefull for my interview. Thank u 🌞
All the best for your interview
Thank you so much for the video
What happened in the end with the c1-c4 in the recycling gas?
They go through the process of Hydrodesulfurization again
@@engineeredlearnings
Hi
But for how long? Don't they need to get out in the end??!
It's a fixed quantity in every cycle, so that doesn't accumulate up
Nice but how can you remove sulphur from diesel 2000ppm to make it 50ppm? Are there any cheap machines out there available? Any suggestions?
You can look out for Sulphur Stripping machines from similar industrial practices if any!
Hello sir, what book would u recommend that would cover Petroleum refining technology and Desulfurization?
And if u have the PDF will u please share it.
I don't have any book pdf. You can refer to Dryden Chemical Technology Book
@@engineeredlearnings thanks sir
Hydrodesulfurization and hydrotreatment that used in used lubricant rerefining are the same process?
Hydrotreatment is done to convert High C No to Low C No to get paraffinic nature but Hydrodesulfurization is to remove Sulphur
Can you share information about dhdt unit if possible
Are you talking about the Diesel Hydrotreating Unit in Refineries. If yes, it works just like a Naphtha Cracker with Hydrogen fed at high pressure and temperature for cracking the diesel to smaller C compounds. Conditions and Catalyst you can find in books or research papers
Explanation is too good but speed of teaching is fast
Thank you for the feedback
Petroleum solvent samel remove formula Sher plz chemical used
Please sir, would a topic such as "production of diesel from plastic waste via pyrolysis and hydroprocessing to curb plastic pollution in town A" be wrong, or is hydrotreatment just the better term?
It's not wrong, it's a different process
@@engineeredlearnings okay so can I specify that since hydro processing is an umbrella term I’d be using hydro treatment in particular?
Yess
Please is there any way to desulfurize pyrolysis oil on a small scale?
What is feed here ? Sir
Any C source which has Suplhur as well. The carbon cuts coming out of Crude Oil Distillation containing sulphur
Are dhdt and dhds the same unit?
Yes
@@engineeredlearnings thanks sir. Just joined as apprentice and alloted the DHDT unit . This video of urs helped me in understanding the basic working of the unit
Glad that it could help
If we want to remove sulphur from h2s, then why again we input h2s from reflux to amine chamber as we already removed,
Please make clear if I am wrong.
Overall you have given very good knowledge.
Please discuss as
1 . KHDS UNIT
2 HGU UNIT
Our primary purpose is to trap S in HCs with pure H2 as H2S and then trap the H2S in amine chamber using amine as it reacts with H2S and traps it. The remaining stream without H2S is refluxed into the main reactor
@@engineeredlearnings correct,gas is leaving at top of the chamber only liquid is going as reflux., Thank you
Keep the boad on full screen bro! Your voice itself is enough.....No offense here😊
Will consider this
