Nitric Oxide Ionization Spectrometry Evaluation (NOISE) finds exact components of process streams. This benchmark technique gives carbon number and Z-number saturation. This hydrocarbon typing can help:
In the NOISE analysis, samples are first separated by boiling point. This segregates look-alike molecules and helps distinguish compounds with traditional reporting catagories. In addition, gas chromatography separates sulfur-containing compounds from aromatics of the same molecular weight. Boiling point fractions are then bombarded with "soft" NO+ ions. Mass spectrometry identifies each component, and reports by boiling region and degree of saturation.
NOISE report gives percentages by boiling point and by Z-number (for CnH2n+z) where Z distinguishes between paraffins, cycloparaffins, mono-, di-, and tri-aromatics. This crucial step of Triton's technique helps refiners control aromatic content and meet changing product specifications. Streams that look alike to conventional analysis can be revealed as quite different with NOISE.
Samples suitable for NOISE Hydrocarbon Typing include:
