Gas Analyses and the calculation of gas properties

When the composition of the gas is crucial. Particularly when the calorific value or Wobbe index needs to be identified. In addition, it is important that the gas is free of detrimental trace components. The possible presence of certain trace components depends strongly on the origin of the gas. Whether or not certain trace components may or may not be present and in what concentration also depends on the application for which the gas is used.

Energy sector, each level in the gas column; from gas producer to gas user. Measurements relating to gas volume and gas quality. Main components, gas properties, higher hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, sulphur compounds (H2S among others), siloxanes, THT odourant.

Kiwa Technology carries out both qualitative and quantitative analyses of components of gaseous fuels (natural gas, LPG, biogas) or any other matrix gas, e.g. air. Given the analysis, it is possible to calculate the properties of these gases, such as calorific value, Wobbe number, density and compressibility. The table shown on the back of this leaflet lists the standard analyses carried out by Kiwa Technology. Please contact us if you need other analyses that are not listed such as water dew point, etcetera.

Kiwa Expert B.V., trading as Kiwa Technology, is accredited by the Dutch Accreditation Council (RvA) in accordance with ISO/IEC 17025 for the activities as specified in our scope, which can be found on the RvA website under registration number L469.

Sampling

Kiwa Technology provides an aluminum cylinder (of 5 liter water volume) and, if necessary, sampling equipment. The sampling equipment is selected based on the pressure (2 – 200 bar) and gas composition (clean or contaminated gas).

You can take the samples yourself.

The number of analyses determines whether Kiwa Technology provides the sampling equipment and one or more sampling cylinder.

Sustainable Gas

Biogas, the product of digestion of biosmass, will increasingly be used as a substitute for natural gas. Biogas which has been upgraded to natural gas quality is also called green gas. The sustainability of green gas is better than electricity produced from biogas resulting from digestion.
