Orbital Gas - Specialist Gas Engineering Company

Gas quality and properties analysis

Orbital have been involved with analysis of natural gas by chromatography for over 15 years and now are the dominant force in the UK transmission industry with virtually 100% of all network entry and transfer controlled by equipment supplied by Orbital. The two main applications areas we are involved with are:

Fiscal ApplIcations
Where Calorific Value, Wobbe, CO2, N2 & other physical properties are reported for instantaneous energy determination.

Gas QualIty Application
Where Calorific Value, Wobbe, CO2, N2, Sulphurs & Hydrocarbon/Water Dew-points are required to satisfy both the shipper and the regulatory bodies ensuring that the gas entering the network complies with all the relevant safety & management regulations for safe operation of the National Transmission System.

Siemens "All - in - One" Gas Chromatograph

In conjunction with Siemens, our long term partner, Orbital developed and released a packaged "All - In - One" gas chromatograph specifically for Natural gas applications.
This innovative instrument provided a compact, fast and less complicated method for gas quality analysis, so, where previously a multi analyser solution (8 off instruments) was required to report the necessary information to comply with GSMR a single analyser could now be installed.

The All - ln - One is a modular instrument enabling a choice of components to be analysed:
C1 to C6+, C6 to C12, CO2, N2, 02, H2, H20, H2S, COS, Odorants
(EM, DMS, TSM, ME:S, DES)

Calculated Data (Safegas Software)
Calorific Value, Wobbe, Hydrocarbon Dew-polnt, Total Sulphur, Compressibility, RD, SG, SI, ICF, I-C

NEW ! - Siemens MicroSAM Gas Chromatograph
Released to the market In 2003, this revolutionary gas chromatograph provides supreme repeatability with an superior cycle time of <3 minuets for an on - line process gas chromatograph using micro TCD (Thermal Conductivity detectors). The instrument is Exd and does not require a controller
