Abstract
A process for transporting deaerated bitumen froth in a pipeline is described which comprises injecting water into the pipeline prior to deaerated bitumen froth injection to wet the interior walls of the pipeline. The deaerated bitumen froth is then injected into the pipeline at a critical velocity above 0.3 m/sec thereby initiating self-lubricating core-annular flow of the bitumen froth.
