ABOUT PETROLEUM PRODUCTION.

1. 1
Petroleum

2. 2
Hydrocarbons: organic compounds consisting of H and C
Petroleum: a thick, flammable, yellow-to-black mixture of
solid, liquid, and gaseous hydrocarbons that occurs naturally
beneath the Earth's surface.

3. 3
Crude oil
* Liquid mixture of naturally occurring hydrocarbons
* After refining: the chief source of transportation fuels
Natural gas
• After processing: used for power generation,fertilizers,
manufacturing, transportation (limited)
* Gaseous mixture of naturally occurring hydrocarbons
Combustion (burning) of hydrocarbons releases
carbon dioxide (CO2) into the atmosphere
Fuel + Oxygen Carbon dioxide + Water + Heat

Petroleum Recovery
As the pressure drops, flow slows and operators must use
“secondary recovery” techniques for to recover petroleum.
The most common technique: injection of water or gas.

Cetane no.- Cetane number, Cetane rating or CN is an
indicator of the combustion speed of diesel fuel and
compression needed for ignition.
Octane no.- An octane rating, or octane number,
is a standard measure of the performance of an engine
or aviation fuel.

Petroleum refining processes
Petroleum refining processes are the chemical engineering processes
and other facilities used in petroleum refineries to transform crude oil into
useful products such as liquefied petroleum gas (LPG), gasoline or petrol,
kerosene, jet fuel, diesel oil and fuel oils.
Unit operation include in petroleum refining
1. Distillation
2. Absorption
3. Extraction
4. Adsorption
5. Crystallization
6. Heat transfer
7. Fluid flow
