EGEE 101 - 2The carbon content of a typical crude oil will range between:
A) 30% to 40%
B) 50% to 80%
C) 10% to 30%
D) 80% to 90% - answer D - Crude ranges from 84% carbon to 89% carbon. The
remaining is Hydrogen 10-15% and small amounts of sulfur, nitrogen, and oxygen
What is OPEC's view on why oil prices are so high?
A) Exporting taxes placed on the oil by OPEC
B) Their manipulation of the oil supply to stabilize the price market.
C) Taxes placed on the oil by the nations consuming the oil.
D) OPEC's price fixing in order to bring in more money. - answerC) Taxes placed on the
oil by the nations consuming the oil.
Correct! TAXES placed on the oil (or gasoline) by the United States is why we see
higher gaso! line prices at the pump. Just be glad we are not paying what countries like
the United Kingdom is paying!
If Iraq IS UNABLE TO SUPPLY OIL, thus cutting the supply of Iraqi oil to the US, what
percentage of the total oil imports will be lost? - answer6%
Approximately 6% of the US oil is imported from Iraq. This is equivalent to
approximately 600,000 barrels of oil per day! This is probably too high now with the
problems Iraq is having exporting oil.
How many gallons of crude i! s there in a barrel?
A) Depends on the size of the barrel
B) 42 US Gallons
C) 50 Imperial gallons - answerB) 42 US Gallons
Correct. When first found, oil had to be transported to market in wagons over rough
roads. There was spillage and losses from evaporation in the Summer so out of about
50 gallons only 42 reached the market. Now we no longer use barrels but it is still the
measure of volume used.
What is required by law to be installed to help minimize the effect of a spill or leak from
the tank?
A) Containment Wall
B) Safety Pressure Valve
C) Irrigation System
D) Fire Extinguishers - answerA) Containment Wall
, In a typical distillation column: the light ends come off from the top. At the top of the
column, what is the temperature relative to the rest of the column?
A) Highest
B) The temperature is even throughout the column
C) Medium
D) Coolest - answerD) Coolest
Correct. A heater is placed at the bottom of the column. The compounds with the lowest
boiling points evaporate and travel up (vapor has a lower density than a liquid, thus
rise). As the vapor rises, it cools (heat is supplied at the bottom). Eventually it is cooled
sufficiently to convert back to a liquid. At this point the compounds are taken out of the
column. Thus at the top of the column, the lightest components are taken off.
True or False: A paraffinic hydrocarbon (straight chain) typically has more hydrogen
atoms than does a branched hydrocarbon with the same number of carbon atoms. -
answerFalse. There are CH3 structures but they are balanced with the CH structures
and so the average of the non-chain ends is CH2. Same as a straight chain.
Which Group was the first to discover underground deposits of oil and gas?
A) Romans
B) Chinese
C) U.S.
D) British - answerB) Chinese
Correct. They were using natural gas well before Christ was born

A) Aromatic Ring
B) Alkane (paraffin)
C) Biomarker
D) Alkene - answerB) Alkane (paraffin)
Correct, the molecule displayed is an alkane CnH2n+2.
98% of all transportation fuel is produced from petroleum. What percentage of
petroleum is used to produce transportation fuels?
A) 30%
B) 98%
C) 10%
D) 50% - answerD) 50%
Correct! Of all the petroleum refined in the US half goes towards producing
transportation fuels. Other products include lube oils, heating oils, feedstocks for
plastics industry, etc.
The highest quality crude oil has which color?
A) Greenish-Black
B) Honey
