At line Analyzer


 

The at-line FTIR analyzer is mainly dedicated to crude-oil identification / characterization, lube-oil and residual materials such as fuel-oil, bitumen and residue.
The system allows automatic sample grabbing, manual sub sampling and automatic analysis using FTIR and advanced Topnir modeling system.

Crude-oil sampling is manually operated using the ISOSAMPLER 1500 or auto processed by the ISOSAMPLE 5100 to drawn under pressure the sample into a floating piston cylinder. Sample collected is kept under pressure during homogenization, sub sampling and analysis at 35°C into the FTIR optical cell and TOPNIR modelling applied for Crude Oil properties prediction. This technology is specified by ISO 3170/71 as the best method giving analytical results that agree closely with on line analysis for split phase products.

Bitumen and residues are auto sampled by the ISOSAMPLE B10 and continuously diluted at constant ratio in Toluene in order to keep the resulting sample pour-point below ambient temperature even for heavier vacuum residues. Manual sub sampling is achieved at ambient temperature for safe and simplified procedure and analysis into the FTIR optical cell operated at 35°C is resulting to spectra representing molecular structure of the mixture. Further to pre-model the bitumen or residue spectra are isolated and TOPNIR modelling applied for multiple properties prediction.
