Natural Gas / BTU Petrochemical

Extrel Process Mass Spectrometers have been widely used to calculate the BTU value of feed streams in Hydrocarbon and Petrochemical applications in order to optimize the efficiency of the processes. Additionally, the ability of the analyzers to provide fast and accurate compositional analysis enables plant operators to tightly control process parameters such as steam to carbon ratios and heating values.

With rising energy prices and the escalating pressure to increase efficiency, the analysis of Natural Gas production and point of use has become a critical need. Since Natural Gas products are priced according to their BTU values, Extrel MAX300-IG Quadrupole Process Mass Spectrometers are in demand to provide fast and accurate analysis critical for product quality control and maximizing Natural Gas revenue. In addition to its fast analysis time, the MAX300 Series Mass Spectrometers implement stream-switching capabilities. One MAX300-IG Mass Spectrometer has all the capabilities needed to replace several conventional BTU analyzers in natural gas processing facilities.

Extrel’s MAX300-IG Series has several advantages over conventional BTU analyzers, calorimeters and gas chromatographs.

Advantages include:

  • Ability to perform full composition analysis in less than 10 seconds
  • Ability to analyze multiple streams
  • Compositional analysis as opposed to receiving only the final BTU value from a BTU analyzer
  • No makeup gas or carrier gas required

MAX300-IG in Natural Gas Applications:

  • Measures the stream components ranging from C1-C6 including butane and pentane isotopes
  • Measures “heavies” such as C6 isotopes, heptane, octane and aromatics such as benzene and toluene
  • Optional electron multiplier detector provides part per million (ppm) analysis of hydrogen sulfide
  • Provides accurate hydrogen measurement when analyzing a blended fuel gas stream such as refinery “off-gas”
  • Performs BTU or heating value calculations and trends this information (in addition to the individual components)
