process targets

(OP)
I am a fresh graduate who has just picked up employment as a process engineer in a small refinery. Can somebody give me some adivise on the possible challenges I would likely meet and how to go about it.Is the any book I can find this information. The process enginer in this refinery is responsible for all the follow up of all the main units(amospheric distillation and the reforming units).

RE: process targets

Hi Padovano,

For beginning, regarding distillation, you can start with:
- Distillation operation by Henry Z. Kister
- A Working Guide to Process Equipment by Norman P. Lieberman

Also Google is excelent tool for finding all kinds of information about refining.

P.S. Did you find out what happend to CDU column from thread 483-186975?

Regards,

Milutin

Thanks mr Milutin.
  As concerns the CDU column of thread 483-186975, it was discovered after gamma scanning that, kerosene was been drawn from two trays lower than were it was surpose to be drawn so after the stripping of the kerosene what went up to the column was more of the "kerosene" which was surpose to be drawn from it rightful tray.The freezing point of what was been drawn from the column was about 20° higher than usual and also the flash point was relatively high. The naphtha feed was highly reformable.

RE: process targets

Hi Padovano,

How can it be possible to draw a side product from ADU tower "two trays lower than it should be" if there is not any draw-off nozzle provided?
If there is a nozzle, it means that process designer has provided additional option to draw this side product as little bit heavier cut - compared to the fraction that is withdrawn from the column two trays above. That is exactly the same configuration as in our ADU: kero fraction can be withdrawn from the 11th tray (as special grade solvent), or from 13th tray (as Jet A1). Taking side-product from lower draw-off tray is confirmed by your laboratory analyses - having both flash and freeze point higher.

Concerning the literature about refinery processes with more detailed look into equipment design and operation, I highly recommend two additional books:

- "Elements of Petroleum Processing", by Jones
- "Process Design for Reliable Operations", by Lieberman

You may also want to look at these excellent websites, with great articles covering a wide variety of subjects:
