ASPHALT PRODUCTION FROM OIL SAND BITUMEN

摘要

Methods are provided for making asphalt from crude oils derived from mined oil sands that have been subjected to a solvent froth treatment as part, of the process for making a crude oil that is suitable for pipeline transport. A froth treatment is used that preserves a greater percentage of the asphalteiie content of the crude oil derived from the mined oil sands.
