Natural gas composition testing and analysis from SGS – understand the composition of your natural gas to reduce risk and maximize value.

Oil storage tanks

Natural gas contains many components other than methane. Some of these components can cause damage to your infrastructure and equipment, endanger your employees, change the market valuation of your natural gas inventories and harm your operations. Understanding the composition of your natural gas will allow you to reduce the risk of corrosion and contamination issues, helping you to run your business more efficiently and maximize value.

Why choose natural gas composition testing and analysis from SGS?

We offer natural gas hydrocarbon composition analysis to support your operations across the entire supply chain, including:

  • Exploration and production operations
  • Natural gas processing
  • Pipeline transportation
  • Gas turbine power plant feedstocks
  • Natural gas trades
  • Liquefied natural gas (LNG) facilities
  • LNG tankers

Natural Gas Composition Reporting

Our nat-gas reporting includes features that will help you to make the most of your analysis.

Multi-Channel Reporting: results from multiple detector channels can be combined into a single report with both raw and normalized amounts (normalized across all channels) displayed.

Custom calculations: you can create custom formulas using GC component results and other results. The results of your custom calculations can be displayed on the printed report, monitored, trend plotted and exported to text files.

Easily update the component list: the list of components to process and report is completely customizable. You can add or delete components from the component list. Natural gas analysis/liquids calculation constants can be loaded from standard data sources or entered manually.

Customized physical properties reporting: the natural gas component list is completely customizable. Components can be added to or deleted from the component list, renamed, and calculation factors (such as heating value, molar mass ratio and summation factor) can be updated using one of the standard physical property tables

Standard physical property tables: standard component physical property tables are provided for the GPA 2145 and GPA 2145 standards, the GPSA Engineering Data Book, GPA TP-17, ASTM D3588, and ISO 6976.

Export to text file: you can create custom export templates to save NGA results to text files for import into flow and measurement systems, such as Flow-Cal and PGAS.

Monitor Results with Alarms: you can use monitored parameters to set up alarms for critical parameters, such as the total un-normalized mole% or conflicting historical data.
