Upgrading
Once bitumen is produced, it is sent for further upgrading, a process that breaks down the heavy carbon molecules in bitumen, converting it into a product similar to conventional crude oil.
The longer the hydrocarbon chains are, and the more carbon heavy the oil is, the more GHG emissions are created during the full product lifecycle. Upgrading breaks down the heavy carbon chains, creating a product known as “synthetic” crude oil that is refinery ready.
Upgrading is accomplished by using either heat to “crack” the big molecules into smaller fragments or by adding hydrogen into the long chains to split them apart.
