PETROLEUM REFINING Crude Oil Molecules come in many different molecular sizes and shapes.
There are four processes used in oil refineries to transform crude oil
into a variety of useful goods.

1) Fractionation of crude oil molecules by size. (e.g. CDU)
2) Breaking larger molecules into smaller ones. (e.g. FCCU)
3) Combining smaller molecules into larger ones. (e.g. Alkylation)
4) Chaniging the shapes of molecules. (e.g. Catalytic Reforming)
NATURAL GAS PROCESSING Below are the key steps from Gas Extraxtion to Transportation.
Controlling the Gas at the Wellhead. By "Christmas tree." [Extraction]
Heating the Gas when it leaves the X-Mas tree, by Heater. [Extraction]
Removing Most of the Liquids. By a 3-phase separator. [Extraction]
Removing Remaining Water. By Glycol Dehydrator. [Extraction]
Gas Processing Plant. CO2 , Hg , Sulfur and H2O Removal.
Transportation to Storage. Pipeline, LNG/LPG
1st GENERATION OIL & GAS PETROCHEMICALS Naphtha as the main feedstock from Refinery enters the “Naphtha Cracker Furnace”
to get cracked while heated up to ~900 DegC. Cracked HC enters “Quench Oil Tower”
and “Quench Water Column” and then gases will be compressed and liquefied in
different temp. down to -150 DegC. Liquefied Gases go Fractionation Terrain where final
products will be extracted in “De-Methanizer”, “De-Ethanizer” “De-Butanizer”
