Petro-SIM 7.0 Miscellaneous Changes

Assay Synthesis

Incorporation of asphaltene characterisation and thermodynamic models from Multiflash
- Represents asphaltenes and resins as components
- Model is tuned against precipitation onset data for crude and then predicts phase behaviour with changing T & P
- Model predicts impact of blending, allowing study of crude compatibility
Incorporation of wax phase modelling from Multiflash
- Handles n-paraffins as separate components, recharacterising on the fly
New assay properties
- Resins – used by asphaltene characterisation and estimated if unknown
- Di-Olefins content – used by new cracked naphtha hydrotreating model
- Difficult Sulfur content to represent benzo thiophenes and other hard sulfur compounds – used in conjunction with other existing sulfur properties to represent four different classes of sulfurs
Synthesis Molecular Weight estimation methods expanded to support full range of Petro-SIM available methods
