Abstract:
Sulfur and Nitrogen are the most abundant hetero-constituents in fuels and process streams. To optimize refining operations, it is of primary concern to determine precisely where in the boiling range span of the processing streams these undesired species are present. Simulated Distillation type gas chromatography with flame ionization detectors (FID) and chemiluminescence detectors (NCD/SCD) for Sulphur and Nitrogen offers quantitative and qualitative information for each species versus the boiling point of the sample. This information may then be used to improve processes and/or quality specifications. The system simultaneously produces boiling point distribution data simultaneously for the 3 channels over a maximum boiling point range from C10 - C90 and even crude oil samples with non-eluting fractions will be handled by the system.
