BOILING RANGE DISTRIBUTION OF GASOLINE AND GASOLINE FRACTIONS
Applications | | FALCONInstrumentation
The boiling range distribution of gasoline and its fractions is a critical quality parameter in refinery operations. Accurate boiling range profiling ensures proper fuel performance, optimizes blending strategies, and supports regulatory compliance. Fast and reliable analysis directly impacts throughput, profitability, and product consistency in both laboratory and on-line settings.
This application note demonstrates the use of the CALIDUS™ 101-HT UltraFast Gas Chromatograph to perform ASTM D3710 boiling range distribution analysis. It highlights the system’s capability to deliver rapid, precise characterization of gasoline samples for product specification, certification, and on-line blending control.
The system employs a Sample Processing Module with a split/splitless inlet for syringe, autosampler, or automated valve injection. Samples pass into a Programmed Temperature Column Module (PTCM) containing a resistively heated MXT-1 stainless steel capillary column. Temperature programming separates hydrocarbon components based on volatility. Detection is achieved via a flame ionization detector (FID) with a detection limit of 1.0 ppm. Data acquisition and analysis are managed by Chromperfect® CDS, InfoMetrix® LineUp™, and Dragon SimDist© software under Windows for streamlined boiling range distribution reporting.
Chromatograms of gasoline and standards demonstrate complete hydrocarbon separation within approximately 200 seconds. Overlay plots confirm baseline resolution and reproducibility. The system’s rapid temperature control and sensitive FID enable precise area normalization and retention time correction, yielding highly repeatable boiling range distributions.
Advances in ultra-fast gas chromatography point to even shorter analysis times with enhanced automation and integration into refinery control loops. Emerging software features will improve predictive blending models using real-time boiling range data. Miniaturization and remote connectivity will expand on-line monitoring and decentralized testing across production sites.
The CALIDUS 101-HT UltraFast GC provides a paradigm shift in gasoline boiling range analysis, combining speed, precision, and compact design. Its compliance with ASTM D3710 and integration with advanced data systems make it an ideal solution for refineries seeking to optimize blending operations, maximize throughput, and reduce operating costs.
