A complex residuum from the vacuum distillation of the residuum from atmospheric distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly greater than C34 and boiling above approximately 495°C (923°F).
Due to the complex nature of bitumens, single numerical values for boiling point are not meaningful. Bitumens are residual products from vacuum distillation. In general they have boiling points (EN15199-2/IP507) over 320°C (hard bitumen usually > 500°C), reflecting the distillation temperature (CONCAWE, 1992a).
