Refinery Gas Analyzers
Arnel offers the most extensive and widest range of Refinery/Light Hydrocarbon Gas Analyzers (RGA) in the industry. The analysis of hydrogen, helium, O2, N2, CO, CO2, H2S and light hydrocarbons from methane through octane in gas and/or liquid samples is addressed. The series of models available are designed to consider all variables and conditions, plus most types of samples frequently encountered in the analysis of Refinery gas.
Standard features on all of Arnel?s Refinery Gas Analyzers include:
- Availability of Pneumatic Pressure Control (PPC) for more precise and automated gas flow
- Factory upgradeable for future expansion or system configuration changes
- Automated, on-line, single or multi-stream sampling capabilities for complete total system integration
- Models that have both gas and liquid sampling capability also have a sample loop purge feature that prevents contamination when changing from liquid to gas samples or gas to liquid samples
- Models that have liquid sampling capability also have filters and back pressure regulation for proper sample introduction into the valve, plus a vaporization zone to properly inject the samples into the columns
- Models with multiple channels (more than one detector) include software (Model 3062) which contains a merge program to combine multi channel data into one report
- Models with He-H2 channels added can be optimized, if required, for lower H2 detection levels
