The formula for calculating Wobbe indix is quite simple. Its the gross heating value (in MJ/Sm3) divided by the square root of the specific density of the gas at standard conditions (15 deg C and 1 atm abs).

What Is The Wobbe Index And Why Is It Im-portant To Natural Gas Systems? Natural gas interchangeability is a key subject in the industry today, and a work group in the American Gas Association has been addressing it. This is a customer-focused effort. The industry is making sure that the quality of the natural gas that ar- The Wobbe Index is actually the correct representation of the heating value of natural gas arriving, from the gas line, at the orifice where a burner is located. specific density of the sample probe.

The Wobbe Index is used to compare the combustion energy output of different composition fuel gases and is frequently defined in the specifications of gas  The fuel having the lower Wobbe Index may be the tail gas of a Fischer-Tropsch synthesis, and materials such as methane, ethane, LPG, or natural gas may be  NATURAL GAS CALORIFIC VALUE/WOBBE INDEX MONITOR pipeline gas fiscal metering and natural gas quality measurement at LnG terminals. Features &  Important aspects of the quality of a gas, in addition to the heating value and the Wobbe Index, are: the composition of the combustibles which influences the  18 jan 2021 Keywords [en].

The corresponding range for the Wobbe index is usually between 40 MJ/m 3 and 60 MJ/m 3. ISO 15971:2008 neither endorses nor disputes the claims of any commercial manufacturer for the performance of an instrument.

Pure H 2 has a Wobbe index of about 1220 Btu/SCF, whereas natural gas ranges from 1235 to 1396 Btu/SCF. Low Wobbe indexes in fuel gases affect combustion efficiency on devices that have been designed to burn natural gas. Definição e usos.

SS-EN ISO 6976 Naturgas Beräkning av värmevärde, densitet, relativ densitet och Wobbe index baserat på gassammansättningen. The question addressed here is to what extent the Wobbe index, a pivotal standard for gas distribution in the Netherlands, can facilitate the transition towards a more sustainable energy system (that is, a hydrogen economy). The current Dutch energy market heavily relies on gas since a large gas field was found in Groningen. Naturgas – Måling af egenskaber – Brændværdi og Wobbetal Natural gas – Measurement of properties – Calorific value and Wobbe index .

The amount of methane in natural gas can greatly affect its Wobbe Index. Most natural gas contains about 90 percent to 95 percent methane by volume after processing.
