Falcon Ultra-Fast GC Refinery Gas Analysis Application
GC analysis of Refinery Gas streams, i.e. fixed gases and C 1-C6+ hydrocarbons for laboratory, at-line, transportable, or on-line, in less than six minutes.
Figure 1: Falcon GC Functional Diagram
The Sample Processing Module with a standard split/splitless injection port, incorporating a heated gas sample valve, delivers the sample to a Programmed Temperature Column Module (PTCM) followed by a column switching valve. The column switching valve allows the fixed gases and C 1 to be switched (“heartcut”) to PTCM2 for further separation and detection by an independent detector. The inlet includes septum purge to prevent bleed components from entering the system.
The two PTCMs are independently controlled by the method.
PTCM 1 contains a MXT-AluminaBond/Na2SO4 resistively heated stainless steel capillary column and is operated in a temperature programmed mode. This column provides initial separation for the fixed gases and C1-C6+. The fixed gases and C1 are heartcut and loaded onto PTCM 2 for analysis and detection on Detector 2 (TCD). Analysis of C2-C6+ remains on this flow path to detector 1 (FID). (See Figure 2)

PTCM 2 contains a MXT-Shincarbon ST resistively heated stainless steel capillary column and is operated in a temperature programmed mode. This column provides further separation of H2, O2, N2, C1, and CO. (See Figure 3)

The analyzer includes the Chromperfect® chromatography data system, fully integrated, with InfoMetrix® LineUp™, running on a Windows PC for calculating and reporting component concentrations.
Refinery Gas streams are a complex mixture of gases produced in the refinery processes. The determination of the composition can be a difficult, but vital process. Product quality and refinery process efficiency depend on the ability to perform this analysis.
Parallel analysis utilizing FID and TCD.
Ideal for determining gas stream composition, with one instrument, in the laboratory, at-line, online, or in the field.
Enables greater product throughput for increased revenues and profits.
Smaller footprint means more bench top or analyzer shelter space. In the lab or the plant, space is always at a premium.
Speed and precision for quicker turnaround.
Reduction in utility and maintenance cost (i.e. power and consumables).
