I. Title Crude Oil Distillation Week 3 iLab
II. Introduction
Crude oil is the combination of gasoline, kerosene, lubricating oils, and other non-
volatile liquids. In the following lab, we will be conducting a distillation experiment of
crude oil. We should be able to observe how the chemical properties of the components
of crude oil influences temperature at which it distills out of the crude oil. With
distillation, we are able to remove impurities like distilled water and sepearate liquids as
well. It allows us to separate substances based on boiling point, in which our case, we
will be boiling crude oil in order to separate its components. When the boiling poin is
reached, the liquid will vaporize into the distillation apparatus. It will then cool down,
condense, and eventually drip out of the apparatus and into the container.
The process of distillation is completed through heating the lquid substance and turning
it into vapor. When it is vaporized, we use the condensor to convert the vapor into a
liquid state afterwards. The components in crude oil are separated from based on
different boiling points for the respected component. Elements that have lower boiling
points would distill first while other elements with higher boiling points would distill
last. When fractional distillation is used, volatile/non-volatile elements may be left
behind during distillation. Fractional distillation is done through a certain machine that
allows various columns and outlets in order to separate certain elements from being
heated.
Crude oil is made of the following: 27% gasoline, 41% lubricating oils, and 32% kerosene.
It starts distilling the gasoline at first, followed by the kerosene, and lubricating oils last
because of their boiling points (gasoline has the lowest boiling point of the three). After
distilling the crude oil, we end up having a light brown material that is 5 mL. During the
mid section of the experiment, the distillate will turn light gray near 25 mL, and with the
given, we managed to conclude that the gasoline and kerosene weighed to be 1.038
g/mL and 1.00 g/mL.
III. Procedure
Step 1
Set up distillation apparatus.
• From the Equipment menu, select Distillation equipment.
• Obtain 100 mL round bottom flask.
• Right click on the flask, select Heating Mantle from the Distillation equipment.
• Right click on the flask, and select Distillation Head from Distillation equipment.
• Right click on the flask, and select Condenser from Distillation equipment.
