REFINERY OVERVIEW


I thought to share this experience as i am working on project for a major refinery. contributed to various units.

I don,t want to replicate what is there in wikipedia and other sources what i will try to explain here is to give an overview of refinery and major issues that generally we face during dynamic model preparation.

Some Common observation:
Point 1:
                    Fractionator, Fractionator overhead section Fractionator bottom section.
Fractionator overhead section objective is to recover Naphtha and oils and Fractionator bottoms will go to another fractionator and process repeats twice means first is CDU or ADU second is VDU and third is DCU objective of all the three is to recover end products.

Overhead section will have treatment units like Amine absorber, one Stabilizer, net gas scrubber,Compressors to increase the pressure as to increase condensing temperature for recovery of end products like LPG,Naphtha and Oils.

Point 2:

Its all about proper data entry, configuring equipment's properly, and Thermo Thermo Thermo..

Thermo - What are all the things you have to see in general during fluid package selection.

Vapor fraction otherwise splits won't happen.
Densities it will create unnecessary problems during flow across ex changers, pumps with integrated models.
Psudo components selection and properties.
Separation - interaction parameters availability if not look for options.
