The 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% - 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. - C) 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? - 6%
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 - B) 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 - A) 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 - D) 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. - False. 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 - B) Chinese
Correct. They were using natural gas well before Christ was born
Green atoms are carbon and blue atoms are hydrogen in this image.
A) Aromatic Ring
