Multi-Purpose Gas Analysis
AC RGA Analyzers 2
Refinery Gas Analysis
• Control specifications and purity of finished gas products: LPG, Ethylene, Propylene and Butenes
• Control downstream processing
• Detect impurities of hydrocarbons, inert gases or acid gases
• Calculate the market value of the gas: Calorific Value
