Oil Sands Ltd. Plant in 1944

Karl Clark was probably the author of a 1944 report that described Robert Fitzsimmons’s separation plant in its final form. The process he found can be summarized in ten points:

  • An elevated wooden tank provided hot water to the system.
  • Oil sand was dumped into a feed hopper shaped like an upside-down pyramid with the point cut off.
  • Steam was added to heat the sand to help it to flow out the hole at the bottom of the hopper.
  • Hot water was added to the sand as it was passed to a feed screw below the hopper, which moved the heated, dampened sand to the next step of the process.
  • The wetted sand next entered a rotary screen, where it was sprayed with more water. The sand passed through holes in the screen, but rocks and debris were removed from the process.
  • The sand then entered a pug mill designed to further mix the sand and water and break down any small lumps.
  • Next, the sand and water moved on to a separation tank where sand could settle to the bottom, and oil could rise to the top. Skimming rakes pushed the oil off the top of the water, and over the side of the tank. Sand was removed from the bottom of the tank.
  • The skimmed oil ran into a wooden settling tank where further sand could settle to the bottom. A pump removed the oil from above the settled sand to a second, cylindrical steel settling tank.
  • Every so often, the process would have to be stopped, so that as much oil as possible could be pumped from the wooden settling tank, and the sand emptied from an opening in the bottom of the tank.
  • The steel settling tank was allowed to fill up with oil. Fine mineral matter settled to the bottom, where it could be drained off. Oil travelled to storage tanks from an overflow near the top of the tank.

A variety of problems were encountered in this system:

  • The rotary screen not only eliminated rocks, it excluded lumps of oil sand.
  • The wooden settling tank filled quickly with sand, requiring frequent shut-downs during which it was emptied. Considerable oil was also lost in this process.
  • The boilers that heated the water and powered the plant were supposed to run on oil separated from the sand. Since the oil was quite gritty, it frequently wrecked the pumps that fed fuel to boilers. Wood was used instead, but this didn’t work well.
  • Water used in the plant was supposed to be re-circulated and reused, but it quickly got dirty and had to be replaced.
  • About 20% of the oil in the oil sand was lost during the separation process.

On the bright side, the “feed hopper performed remarkably well,” and the “settling of the sand from the oil was done in a crude way which worked surprisingly well.”
