of the total oil imports will be lost? Correct answer-6%

600,000 barrels of oil per day! This is probably too high now with the problems Iraq is having
exporting oil.

, EGEE 101 - 2 Exam 2; Questions & Answers
100% Correct

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 Correct answer-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 the temperature relative to the rest of the column?

A) Highest

B) The temperature is even throughout the column

C) Medium

, EGEE 101 - 2 Exam 2; Questions & Answers
100% Correct
D) Coolest Correct answer-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.
