Custody Transfer Gas Chromatograph
Description:
Gas Chromatographs (GC) are versatile and reliable online natural gas analyzers.
Robustly designed by engineers and experienced field technicians. The GC’s are designed to operate in remote production areas with dirty samples, unreliable power, no instrument air and limited maintenance.The Envent GC provides accurate and reliable full compositional analysis of Natural Gas or Natural Gas Liquids (NGL’s) including physical property calculations. Custody transfer energy measurement applications are also supported with analysis to C6+, C7+ or C9+. An extensive library of physical property calculations is available in accordance with applicable AGA and ISO natural gas standards.
Typical Applications Natural Gas
