“Dehydration of oil shale”
Oil shale is composed of between 17 and 25% water and before the oil can be extracted, this moisture needs to be removed. To extract the water from the oil shale, the shale passes through a drying plant, like an enormous pizza oven, in which hot air is blown over it at 200 degrees Celsius. In this lesson, an experiment is conducted to reproduce this process and determine just how much water a rock can hold.
This lesson has been designed to align with the science Australian Curriculum year 8.
