CEN SFGas GQS –Impact of renewables on Wobbe index (WI) proposal • Blending of hydrogen or lower WI biomethane into a natural gas stream results generally in a decrease of the WI. • The proposed lower WI entry range reflects this. • The classification can also be applied for these blends. • Remark: injection of these gases, 2018-09-15 · Wobbe index is an indicator of the interchangeability of fuel gases whereas Calorific value is the total amount of heat energy that a unit mass of fuel can produce when we burn it completely. Therefore, this is the key difference between wobbe index and calorific value.

Priserne ligger for brændværdi-/wobbemålerne i området 140.000 – 410.000 DKK, hvor de højeste priser også omfatter et fuldt udrustet, opvarmet kabi- Wobbe Index / Calorific Value / CARI The COSA 9610™ is the one of the latest instruments from COSA Xentaur for measuring Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement Index). Model No. COSA 9610. Wobbe Index Calorimeter / BTU. Residual Oxygen. Energy. Petrochemical. Users must manually calculate caloric values, specific gravity, Wobbe Index, and other values using the actual temperature and pressure of the sample in question. The Natural Gas Analyzer GC can be configured with a TCD detector only, for detection limits in the 200-300 ppm range.

Field of Applications and Limitations Both configurations are only suitable for analysis of natural gas or natural gas like mixtures. The presence of interfering components like higher hydrocarbons starting from C 3 8 Pure methane has a Wobbe number of 1363; natural gas as piped to homes in the United States typically has a Wobbe number between 1310 and 1390. Equipment is rated to operate over a specified Wobbe Index range and, in some cases, provides an adjustment that corresponds to the Wobbe Index. The Wobbe Index indicates the interchange ability of a fuel gas and is the best indicator of similarity between natural gas and a specific propane-air mixture.

The Wobbe Index is sometimes called the Interchangeability Factor.¹ Symbol, WN or WI.² . The Wobbe number is named for the Italian engineer Goffredo Wobbe, who in 1926 published a paper³ defining a measure of fuel gas “quality”, with the idea that fuels of the same quality would be interchangeable.
