Overview

THE PURPOSE OF AN OIL REFINERY IS TO TRANSFORM RELATIVELY LOW VALUE CRUDE OIL INTO HIGH VALUE PRODUCTS AS EFFICIENTLY, PROFITABLY AND ENVIRONMENTALLY SOUND A WAY AS POSSIBLE

History of Use

• 1000 A.D. Arab scientists discovered distillation and were able to make kerosene. This was lost after the 12th century!

• Rediscovered by a Canadian geologist called Abraham Gesner in 1852

Abraham Gesner (1797-1864)

History of Use

• 1858: first oil drilled in Canada

• 1859: Edwin Drake!

• Who is he? – He was the first person in the U.S. to drill for

oil

• Where? – Titusville, Pennsylvania

What Is Crude Oil?

• Crude Oil is a liquid mixture of thousands of organic chemicals found underground. It is the result of organic matter decaying over thousands of years; hence the name fossil fuel

• Crude oil is found all over the world and varies tremendously in its density, aromatics, sulfur, and metals content

Source of Oil

• What do we need?

- Source rock

- Reservoir rock

- Cap Rock

- Traps

Oil Refining

• Method by which crude oil converted to petroleum products– (I think that a barrel (42 gal—

produces 44 gal of petroleum products)

• Distillation (fractionation)– At high temperature the lightest

fractions rise to the top of a tower, heavier fractions condense at bottom

Oil Refining

• What we get out of oil now with modern refineries:– 50% gas– 30% fuel oil– 7.5% jet fuel

How long will it last?

• Quick Calculation. According to the previous graph we use about 72 million barrels per day. Oil reserves are 1201.332 billion barrels.

• This equates to approximately 45 years of oil!

How long will it last?

What Role Do Chemical Engineers Play?

• Operations Engineer• Maintenance Engineer• Control Systems

Engineer• Design Engineer• Health/Safety/

Environmental Engineer• Planning / Scheduling

Engineer• Reliability Engineer• Plant Manager

Other Ways Chemical Engineers Support The Refining Industry

• Research & Development Engineers

• Technical Sales Engineers

• Engineering & Construction Engineers

• Governmental Regulators (EPA)

• University Professors
