ChromSolutions: Refinery Gas Analyser - Quick Reference Guide
The Refinery Gases Analyser, (RGA), is a standard turnkey solution to refinery gas analysis. The analyser is suited for all types of refinery gases, including stack, flame and reformer gases. The analyser has evolved from a standard RGA to a rapid RGA.
The GC Analyser has 3 channels with a multi-valve design using both capillary and packed/Micropacked columns. The system is divided into 3 channels:
- Light Hydrocarbons, (LHA)
- Permanent Gases, (PGA)
- Hydrogen, (H2A)
This multi-channel/multi injection approach to complicated samples is a common theme with dedicated analyser design. The 3 sample loops shown in the diagram below are all linked together, so the same sample flows through each of the loops. When the loops are switched into the injection position, the same sample is placed on each channel. The RGA has a number of forms, for example a full analysis or a rapid analysis also an RGA can be built on a number of different GC chassis.
ChromSolutions: 3 channels of the GC Analyser.
The Rapid RGA can be equipped with optional Liquid Injection Valve on the light hydrocarbon channel. For liquefied gases such as LPG or high pressure samples the optional Micro-Gasifier can be used in front of the Rapid RGA sample injection valves. The Micro-Gasifier evaporates liquefied gases and reduces high pressure gases into low pressure gases preventing any sample discrimination.
