Rapid Analysis of NG composition using a single module Micro GC Fusion

Rapid Analysis of Natural Gas Composition Using a Single Module Micro GC Fusion.

Rapid and precise analysis of the chemical composition and physical properties of natural gas is critical for natural gas producers, gatherers, and gas distribution companies for custody transfer. In addition, natural gas engine, boiler, and
appliance manufacturers rely on natural gas calculations to determine key development specifications, such as thermal efficiency.

Due to the variations in natural gas composition, it is necessary to monitor the physical properties of the gas, such as compressibility, relative density, and heating value (in British thermal units, or BTU). Small differences in heating value can have significant financial impacts. Building on proven microelectromechanical systems (MEMS) technology, Micro GC Fusion is capable of analyzing C1-C8 “plus” (methane through octanes “plus” hydrocarbons and fixed gases present in natural gas) using a single module. The temperature programmable column allows for runs to be conducted quickly, reducing the cycle time of analyses and increasing sample throughput. Temperature programming also allows for
rapid column cleaning, which prevents contaminants from remaining in the column and negatively impacting its lifetime.

The web-based Micro GC Fusion user interface combined with Diablo EZReporter automatically calculates chemical composition and physical properties after each sample run. The software generates a standard report using industry specific methods from one of the following standards:

  • GPA (Gas Processors Association) 2172, 2145- 09
  • ASTM (American Society of Testing and Materials) D3588
  • ISO (International Standards Organization) 6976
