High-Accuracy Crude Oil Characterisation Using Simdist-DHA Merge
Accurate boiling point distribution data is essential for crude oil valuation, refinery planning and process optimisation. Conventional simulated distillation methods such as ASTM D7169 and ASTM D7500 provide fast results, but can suffer from limited resolution in the C5–C9 range and interference from carbon disulfide used as solvent.
The GAS Crude Oil Analyser – Simdist-DHA Merge combines high-temperature simulated distillation with Detailed Hydrocarbon Analysis (DHA) front-end data according to ASTM D7900. By merging high-resolution DHA data for light hydrocarbons with Simdist results for heavier fractions, the analyser delivers a single, highly accurate True Boiling Point (TBP) report. The system integrates two dedicated GC analysers with a shared autosampler and fully automated calculations in Chromeleon CDS, resulting in improved accuracy, efficient operation and reduced laboratory footprint.
Applications
- Supported method: ASTM D7900
Perform Simdist-DHA merge calculations fully compliant with ASTM D7900.
- Crude Oil Boiling Point Distribution
Generate accurate TBP curves by combining DHA front-end and high-temperature Simdist data.
- Refinery Feedstock Evaluation
Characterise crude oils for blending, pricing and refinery optimisation.
- Simulated Distillation Replacement for D86 / D1160
Use fast, reliable GC-based boiling point determination instead of labour-intensive physical distillation.
- Laboratory Reference and Method Development
Support advanced crude oil characterisation with detailed hydrocarbon resolution up to C9.
Benefits
