    and/or lab-techs for oil sands labs.

Oil Sands Investigations
  • These bitumen from oil sands investigations have
    been prepared by teachers with the assistance of
    the Alberta Ingenuity Centre for Oil Sands
    Innovation (COSI) in the Faculty of Engineering
    at the University of Alberta.
  • The program is administered for Alberta Ingenuity
    by the Centre for Mathematics Science and
    Technology Education (CMASTE) in the Faculty of
    Education at the U of A.

The Story of Bitumen from Oil Sands
  • The photo at the right is of a display of oil
    sands, bitumen, synthetic crude, coke, sulfur and
    sand.
  • Mining leads to extraction of bitumen from oil
    sands, upgrading of bitumen to synthetic crude,
    and refining of synthetic crude into components
    like gasoline (see flowchart).

Genesis of School Lab Idea
The idea for these investigations in vials came
serendipitously when visiting the Oil Sands
Discovery Centre in Fort McMurray. The
spontaneous reheating of a vial that showed the
extraction of bitumen from oil sands workedagain
and again. This eventually led to the creation of
the investigations described hereinstudying
variables that affect bitumen extraction.

First Perturbation
Another effort that has proven fruitful is the
use of canning jars to demonstrate bitumen
extraction and solubility. The jars are more
available and provide a larger demonstration
model. However, be careful about placing
flammable solvent in glass jarsplastic is
better. Plastic is not better for bitumen
extraction from oil sandit sticks to the plastic
sides. Likewise glass beakers are better than
plastic.

Research Program Projects Variables Affecting
Bitumen Extraction
  • Research Projects
  • temperature
  • quantity of air
  • pH
  • Ca2(aq) concentration
  • quality of oil sands

8
Design, Materials and Procedure
  • Design Manipulate one variable control all
    other variables (e.g., temp., pH, and air)
  • Materials glass vials, oil sands, water, air,
    NaOH(aq), CaCl2(aq), etc.
  • Procedure Prepare vial with oil sands, water and
    air. Adjust temperature or pH. Observe and
    measure the effect.
  • (Students write Design and Materials from
    Procedure.)

9
Preparing oil sand samples
  • Placing the frozen oil sand into vials is time
    consuming.
  • Add about 3 cmto a mark on the vial.
  • Place on a balance that is tared and adjust for a
    controlled mass of oil sand.

1. For temperature manipulation
  • Prepare three identical vials with a pH of 9.
  • Add pH 9 (NaOH(aq)) solution to 7 cm mark on each
    vial.
  • Screw the top on tight and/or glue it shut.

11
2. pH manipulation
  • Prepare three vials with 3 cm of oil sands
    (adjusted to an equal mass on a balance).
  • Add pure water to one vial for a pH of 7.
  • Add pH 9 solution to the second vial.
  • Add pH 11 solution to the third vial.

12
3. Adjust the quantity of air
  • Prepare three vials with 3 cm of oil sand
    (adjusted to an equal mass on a balance).
  • Add pH 9 solution to each vial while leaving air
    equal in height to 6 cm, 3 cm and 0 cm of air.

13
4. Adjust Ca2(aq).
  • Prepare three vials with 3 cm of oil sand
    (adjusted to an equal mass on a balance).
  • Add pH 9 solution (adjusted for CalCl2(aq)) to
    each vial while leaving air equal in height to 4
    cm of air3 cm oil sand, 4 cm of solution 4 cm
    air.

0 mmol/L 1.0 mmol/L 10 mmol/L Ca2(aq)

5. Adjust the quality of oil sand
  • The quality of oil being mined is variable e.g.,
    with concentration of bitumen and Ca2.
  • Dried out rich oil sand can be used to simulate
    lean oil sand. There is no need to order lean oil
    sandjust dry out some rich oil sand.

  • This series of investigations is aimed at
    improving the extraction of bitumen from oil
    sandsespecially to reduce energy and water usage
    and environmental impact.
