Natural Gas Analysis | EffecTech UK

Our ISO accredited calibration gases ensure accurate and traceable calibrations through an unbroken chain of measurements back to the SI unit amount of substance, the mole. We ensure you receive the best solution for your application, drawing on years of experience 2874 gas metrology.

Flow Validation Services EffecTech specialises in performing ISO accredited calibrations and validations of the secondary elements of any gas fl ow metering system. If you need help with the purchase or have any queries please email enquiries standards. In order to exploit the boiling point and hydrocarbon component elution time relationship to identify unknown components using a process gas chromatograph, the author developed his own 2874 and a modified method of the ISO standard.

Essential safety You may be interested in this related standard Specification for reticulated natural gas You may be interested in this related standard.

Therefore the aim of this project was to research the ‘equations of state’ used to calculate natural gas hydrocarbon dew point from constituent analysis by Gas Chromatography and to develop a methodology to improve Gas Chromatography hydrocarbon dew point determination. Typical customers are large consumers of gas such as power stations and producers including gas transmission and LNG terminal operators where the end user does not own and maintain the fl ow measuring equipment.

EffecTech offers a troubleshooting and consultancy service to investigate and identify metering errors, lost or unaccounted for gas and suspected metering or energy imbalances across plant and hydrocarbon accounting chains. The faster, easier way to work with standards. Accept and continue Learn more about the cookies we use and how to change your settings.

We also witness metering validations as an independent third party.

Gas chromatographic requirements for hydrocarbon dewpoint calculation Status: Operators require this to demonstrate that their natural gas measurement systems are operating as expected and that optimal performance is being maintained reducing signifi cant mis-measurements which may compound over time leading to large financial discrepancies.

Calibration Gases Gas chromatography and gas analysis is a comparative method and as a consequence the calibration gas is the principal driver for the accuracy of the analysed gas composition, and that of any physical property calculated from it. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

ISO — Testing View accreditation schedule This accreditation covers the analysis of natural gas from customers’ sites to determine the physical properties of the gas — Natural Gas Analysis.

Accreditations See a full list of our accreditations. The reason for this, is that the process type gas chromatograph does not have a method to identify these species between the normalised alkane components in the C6 to C8 carbon groups.

Regular site Inspections and performance evaluations provide confidence in the metering system and objective evidence that the gas is being metered correctly. The limitation of the ISO standard is that it is only applicable for laboratory analysis type gas chromatographs.
