Petroleum, or crude oil, is a naturally occurring flammable liquid that consists of complex chains and bonds of hydrocarbons with varying molecular weights. It also contains other organic compounds that are found in geologic formations beneath the earth's surface.
Petroleum is a complex mixture of many different organic chemicals. Consequently, there is no single "chemical formula" for petroleum.

The majority of processes involved in petroleum refining are chemical changes.
Hydrocarbons, usually produced with natural gas, which are liquid at normal pressure and temperature.
Petroleum. For details about the chemistry you might wish to consult the benzene page on wikipedia.
The design of gasoline and fuels are an interdisciplinary subject matter. Gasoline is a hydrocarbon, and thus an organic by definition. Chemical and Petroleum Engineering involve organic chemistry knowledge and applications.
Organic chem. It involves carbon (and hydrogen) elements
The majority of processes involved in petroleum refining are chemical changes.
Petroleum industry is totally based on chemical equations, procedures, theories.

Silicone is not a product of petro-chemistry.

Feedstock is the stuff you start with... probably crude oil for petroleum chemistry, though you might begin with a particular fraction of the oil instead of crude.
In chemistry, ppm means 'parts per million'

The feedstock for polymers chemistry may be petroleum, methane gas, coal, plants.
Mendeleev worked also in spectroscopy, ethanol-water system, capillarity, petroleum chemistry.
How do you educate doctors without chemistry? How do you educate researchers in plastics industries, or petroleum, or metallurgy, or ... etc. Added: As someone who has taken three years of undergraduate chemistry ( though much is forgotten! ) I can tell you that chemistry is education; the subject teaches you how to think, not what to think.
The entire science of chemistry (which requires years of study to learn) is brought to bear upon the problem of creating petroleum based products, so there is no simple technique that can be described for you. There are thousands of petroleum based products and thousands of different techniques used to create them.
