Natural Gas Analyser (NGA)

Introduction
The Natural Gas Analyser (NGA) is configured for the complete analysis of natural gas in a single run, with column switching. To shorten the analysis time, a backflush valve can be installed in the instrument. This procedure yields rapid elution of the combined C6+ fraction.

To suit the requirement, the Natural Gas Analyser can be offered in various different configurations:

Simple Run Analysis, Analysis with initial backflush, Trace analysis of residual gases, Helium/O measurement, 2 Extended NG liquid analysis as per GPA 2286

Features & Benefits:

  • High level of automation.
  • Its dedicated software controls all events within a gas chromatography system, including calibration and reporting of calculated physical properties and individual components of natural gas streams.
  • Determines hydrogen sulfide, oxygen, nitrogen, carbon dioxide and hydrocarbons from C1 through C6+ with Sulfa inert system (optional).
  • Optional Liquid sampling valve or Auto liquid sampler with DHA software for C1 to C15 detail Hydrocarbon analysis.
  • Rapid analysis of C1 to 6 +, N , O2, CO2 in a single run.
  • Extendable to C10 analysis.
  • Optional analysis of H2S in trace levels using FPD.
  • Available in various different configurations.
  • Reports highlight : Specific gravity, calorific value, vapor pressure, Wobbe number and molecular weight results etc. as per ASTM D3588 or ISO 6976.
  • Low dead volume microvalves.
  • Multidimensional system.
