Refinery Gas Analyzers
SCION Instruments refinery gas analyzers are designed to deliver superior, reliable results for various sources and analysis throughput requirements.
SCION’s refinery gas analyzers (RGA) are ‘turnkey’ systems pre-configured and tuned at the factory to conform to key industry standard methods including: ASTM D7833, ASTM D1946, UOP 539, and DIN EN 15984. SCION Refinery Gas Analyzers employ a proven and optimized multi-channel approach. They determine the concentration of individual saturated and unsaturated hydrocarbon components up to and including C5 (C6 and higher components as a composite peak) and all permanent gases, including hydrogen, helium and hydrogen sulfide in a single analysis.
SCION RGA analyzers not only incorporate proven GC hardware and software but also arrive pre-loaded with analysis methods, and include documentation specific to the application required.
Description
SCION offers two RGA systems to meet the widest range of analysis requirements:
Standard RGA:
A three-channel SCION 8500 GC with a multi-valve design using both capillary and packed columns. The first channel is explicitly optimized for hydrogen and helium separation, the second is designed for the other permanent gases and the third is for light hydrocarbon. The system is configured and fully tested in accordance with industry standard methods. The total analysis time for all components is under 32 minutes. The standard RGA analyzer is the most powerful tool to analyze the widest range of RGA type streams.
Rapid RGA:
A three channel SCION 8500 GC that utilizes a multi-valve design in which the packed columns used in the Standard RGA are replaced by micropacked columns in both the hydrogen and permanent gas channels. Since the micro-packed columns are installed in a separate heated zone, the capillary columns located in the GC oven can be temperature programmed in a more aggressive manner. For high sample analysis demand, the Rapid RGA Analyzer concept substantially reduces overall analysis time by 5 minutes (7 minutes when including H2 S) compared to the 31 minutes with the standard RGA
