Hi,

I am student of Chemical engineering and am in my last semester of bachelors. I am studying a course of refinery design. My problem is that I am unable to grasp the concepts of the ASTM, TBP curves, their inter conversion, prediction of cut properties from them conceptually. The procedure is fine but I would like to understand conceptually what is going on- what is the logic behind using vol. basis or wt. basis to find properties. Our instructor suggested Jones - Handbook of petroleum processing but it has many mistakes and is really not very clear.

Could some one please suggest some reading material.

Thanks

Rohit Mittal

Hello Rohit,

You can try with "Crude oil petroleum products" from IFP, or "Petroleum refinery engineering" by W. Nelson. There is an interesting set of information in API databook as well.
I also remember some interesting materials being available on Axens' website (http://www.axens.net) but I'm not sure if they are still somewhere there.

Good luck with your search,

Hi,

u can go through the book Petroleum Refining Processes by Bhaskar rao.. I think it is a good book for the learners..

for further query u can contact me at any time. I am working in Foster Wheeler India Private Ltd.,kolkata as process engineer and presently busy in CDU design of a grass root refinery in Vietnam.

Dear Zauberberg and Shubhasis,

Thank you so much for your replies. Zauberberg, I didnt have access to the books you told about. I'll keep trying nevertheless. Shubhasis, I went through the book you told. The book only had examples the concept of TBP is also not explained very well. But still, it is much better than what the book I already have.
Actually, I am studying in the last semester of chemical engineering at IIT Guwahati, India. This placement season was reaaallly tough and I got a job in a PSU oil company. I thought I'll not learn a lot there (with the PSU image and all) so I decided to try for a masters in Petroleum Engineering. So I just thought I should keep my fundamentals clear.

Hi,

Yes, IITG does offer PhD programs. However, it depends upon which program and research area you want to work in. Try looking at the website and see if there's any professor whose research interest matches with yours.

Good luck,

Dear Rohit,
I understand from your posts that either you are running very fast or you are taking all these things superficially. I am working with an OIL PSU in India so as far as the learning potentail is concerned it totally depends on every individual. Any industry across the globe will never do spoon feeding to its new joinees. So please first be clear in your query. What you want actually. Looking forward to help you more.

Dear Padmakar,

Don't take this otherwise, since I am not casting aspersions on any individual or group of individuals but only expressing the impression most middle class and educated Indians carry about their PSUs.

I couldn't agree more with Rohit. All PSUs in India follow a policy of reserving openings for certain sections of the Indian society. Many of these candidates from such sections of the society wouldn't be even granted an interview in top notch private companies which thrive for
excellence in their line of business and are very conscious of the quality of man-power they hire. There is a good reason for this. Many of these candidates who have qualified as engineers are neither good students nor have they made any efforts to bring an improvement in themselves. They thrive entirely due to their political and class connections which generally govern the PSUs. No wonder, that many of the talented staff in PSUs have turned to greener pastures which have proved rewarding both financially and from the view-point of job satisfaction. In a nutshell, PSUs in India are sustained by government subsidies & 30% staff who actually run the show while the rest of them are just parasites to the organization.

I reiterate that this is not a statement against any individual or group of individuals but the general condition of PSUs in India which have become a hotbed of malafide political activity and who are being sustained by government largesse rather then on their own merit.

Ankur.

Dear ankur

I realize that you might have been over overwhelmingly compelled from inside to show the expressions; you felt justified.

I submit that situation is similar all over the normal world 'in general'

As either political links or influential links and group's affiliations and otherwise.

as such too strong words selected might have been softer.I suggest.

Best regards

Dear Padmakar, others,

I am really sorry if my words offended or insulted you. In retrospect, I realize it was immature on my part to have made such judgements without adequate knowledge. However, I believe that I have some concerns about working in a PSU, which may or may not be correct after all. That is all I wanted to say. And yes, my expectation does not include getting spoon fed. My expectation is just that I get to work in an environment that adds to my motivation to work and not the opposite.

Please allow me to address my concerns, which again, may be legitimate or not:
1) I think that despite being quite a motivated individual, I might start getting complacent if expectations from my work is very less. Thus, I fear developing a laid back attitude at the start of my career.
2) If I wish to switch over to a private company, where work pressure is considerably higher, will I have problem convincing that I can easily adjust?
3) I have also heard that promotions, performance appraisals, etc gets bogged down due to red tape in PSUs. And nepotism also comes into play.

I am sure Ankur also did not mean to hurt anyone, maybe he also has conceptions about PSUs. I hope we easily clear them up with a healthy discussion. Anyways, I have managed to clear many of my original doubts about TBP and ASTM curves. All the help I have got on this page is very encouraging. Its always great to keep in mind that there are experienced people like all of you out there who are willing to help fresh graduates like me.

Thanking you,
Rohit

Dear Shubhasis,


Can you give me the infomation regarding the cracking characteristics of Reduced crude oil?

My aim is to reduce the cracking of reduced crude oil in vacuum heater so that i can minimize vacuum unit overhead gas. At the same time i can lift the VGO cut point to minimize VGO loss in VR.

Are there any correlations formulas and graph or any other information regarding this?
