Measurement and Modeling of Pentane-Diluted Bitumen Phase Behaviour
The phase behavior of mixtures of bitumens and n-alkanes is a key factor in the design and optimization of solvent-assisted heavy oil recovery processes and solvent deasphalting processes. However, data and comprehensive models are lacking for these mixtures. Crude oil phase behavior is typically …

Quantification of Trapped Diluted Bitumen Droplets in Gravel: an Experimental Study
Adverse environmental effects caused by diluted bitumen (dilbit) spills have led to serious public concern. Compared to marine systems, the cleanup of oil-contaminated sediment in rivers is more difficult. Hyporheic flow, where surface water flows through the streambed, is one of the contributing …

Quantifying the U.S. Coast Guard Ecological Risk Assessment on Diluted Bitumen
… Consensus Ecological Risk Assessment (CERA) on diluted bitumen (DB) and compare the toxicity of DB to conventional crude (CC) oils. At the height of the domestic energy renaissance, 103,000 barrels of DB were transported via railcar each day to five refineries throughout the Delaware Bay …

Bioaccumulation and Toxicokinetics of Polycyclic Aromatic Compounds and Metals in Giant Floater Mussels (Pyganodon grandis) Exposed to a Simulated Diluted Bitumen Spill
Canadian bitumen is mainly transported in a diluted form via pipeline and train, all posing a risk as they can lead to the release of diluted bitumen (dilbit) in the environment. In the summer of 2018, a collaborative large-scale field experiment was conducted at the International Institute for …

The Phase Behavior of Heavy Oil and Propane Mixtures
The phase behavior of propane diluted bitumen was mapped from temperatures between 20 and 180°C and pressures up to 10 MPa. Both vapor-liquid (VL) and liquid-liquid (LL) regions were observed. High pressure micrographs demonstrated that the heavy phase (a pitch phase) transitioned from a glass to a …

Precipitation, Aggregation, and Settling of Asphaltenes from n-Alkane Diluted Bitumens
… and settling of asphaltenes from solvent diluted bitumen. Models and data that include the effect of solvent type, concentration, shear, and contact time on asphaltene precipitation and settling are required to design and optimize these processes but are lacking or are specific for …

Understanding government and railroad strategy for crude oil transportation in North America
… themselves, such as a potential spill of diluted bitumen, but there is also concern about the consequences of greenhouse gas emissions caused by the energy-intensiveness of bitumen production and refining. Proponents argue that a denial of pipeline permits by governments in Canada and the …
