The Value of Groups

“There are basically two types of people. People who accomplish things, and people who claim to have accomplished things. The first group is less crowded.” -- Mark Twain (American Humorist, Writer and Lecturer. 1835-1910)

LinkedIn membership offers many advantages. One of them lies in the many LinkedIn groups available.

The Value of LinkedIn Groups ...
1) Occasionally you learn something useful
2) You identify potential experts in specific technologies
3) You find someone who might want to join your LinkedIn network

For example, here is part of a recent discussion from the LinkedIn Petroleum Downstream group

What unit would be good alternative for Delayed Coking Unit in a refinery scheme? Feedstock is vacuum residue or slurry from FCC.

One answer ...

From Simion Grigor • Hi, Teymur!
In the absence of Coking Unit the best route for VR is to go into Propane De-Asphalting Unit .
If you don't have any Deasphalting Unit we can discus about how to get a second hand one, or to refurbish an existing unit into PDA, or to engineer a new one .
The Propane Deasphalted oil , getting out from the PDA Unit is the so called ‘Bright Stock’, actually an excellent quality lubricant and most valuable base oil stock that makes most of the lubricants recipes.
The PDA Unit produces good quality road bitumen, that can be used as it gets out from PDA Unit , or blended with cutting stock.
The road bitumen produced in this way is hard ,though elastic , resilient, highly resistant to Ultra-Violet aging action , highly resistant to seasonal temperature variation , etc . due to its high % in asphaltenes & maltenes and most important due to its stabile chemical formula , providing this is NOT AIR BLOWN ASPHALT , therefore does not contain oxigenated chemical components which are most susceptible for road bitumen aging.
As concerning the FCC Slurry, the best is to separate as much as you can the spent catalyst by filtering and to use the resulted heavy oil as component for FO, or alternatively to pass the Slurry to Vacuum Unit in order to recover some cracked heavy fuel oil , whilst the VR goes for rodd bitumen .
Please feel free to discus with me the above issues.

Best regards,
