Operators require this to demonstrate that their natural gas measurement sio 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. UKAS provides accreditation to conformity assessment bodies that carry out conformity assessment in accordance with standards.

As part of its commitment to staff development, EffecTech has successfully maintained its Investors in People IIP accreditation for over five years. Improvement of hydrocarbon dew point determination via gas chromatography.

Accreditations News Careers Contact Us. 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 can take many forms. Regular site 238774 and performance evaluations provide isoo in the metering system and objective evidence that the gas is being metered correctly.

The faster, easier way to work with standards.

A gas chromatograph is the most common method to continuously determine the hydrocarbon dew point of export natural gas.

Apart from product standards, other examples include: It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. 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.

These standards, which currently underpin the use of gas chromatography for gas quality measurement form the basis of many commercial contracts. Sampling can be provided by one of our experienced engineers with comprehensive training to local staff for subsequent activities.

In addition, we provide physical properties according to ISOhydrocarbon dewpoint to ISO and other combustion properties such as carbon emission factors.

This accreditation covers all calibrations carried out in the EffecTech laboratories and on gas quality measurement systems at customers’ sites, including calibration gases and performance evaluations — Calibration Gases. 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. It is used to ascertain the composition of the natural gas mixture which is applied to a thermodynamic equation of state.

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. This covers the provision of the inspection of gas quality measurement systems — Performance Evaluation and Inspections. One important characteristic of the gas chromatograph, is that the measurement of carbon fractions greater than pentane, n – C5, is based on the relationship of component elution time and hydrocarbon boiling point.

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 method and a modified uso of the ISO standard. 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. The limitation of the ISO standard is 238774 it is only applicable for laboratory analysis type gas chromatographs.

The International Standard Organistation standard ISOuses this relationship to calculate the boiling points of unidentified hydrocarbon components by linear interpolation between the normalised alkanes.
