  2. Natural gas storage - Wikipedia

    en.wikipedia.org/wiki/Natural_gas_storage

    Gas storage facilities are gaining more importance due to changes in natural gas demands. First, traditional supplies that once met the winter peak demand are now unable to keep pace. Second, there is a growing summer peak demand on natural gas, due to electric generation via gas fired power plants .

  3. Wobbe index - Wikipedia

    en.wikipedia.org/wiki/Wobbe_index

    The Wobbe index is expressed in MJ/Nm³ (where 'Nm³' indicates'm³ in Normal conditions), or sometimes in BTU/scf.In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 39 MJ/Nm³ (1,050 BTU/scf) and the specific gravity is approximately 0.59, giving a typical Wobbe index of 51 MJ/Nm³ (1,367 BTU/scf).

  4. Natural gas prices - Wikipedia

    en.wikipedia.org/wiki/Natural_gas_prices

    North American natural gas injections (positive) represent additional demand and compete with alternative uses such as gas for heating or for power generation. Natural gas storage levels significantly affect the commodity's price. When the storage levels are low, a signal is being sent to the market indicating that there is a smaller supply ...

    Pipe marking on a natural gas pipe. In the process industry, chemical industry, manufacturing industry, and other commercial and industrial contexts, pipe marking is used to identify the contents, properties and flow direction of fluids in piping. It is typically carried out by marking piping through labels and color codes.

  8. Strategic natural gas reserve - Wikipedia

    en.wikipedia.org/wiki/Strategic_natural_gas_reserve

    Most gas storage is in depleted gas or oil fields, with the second largest storage capacity being in aquifers, and the smallest in salt caverns. Depleted gas or oil fields are the cheapest to commission, as they take advantage of existing wells, internal distribution systems, and pipeline connections. They are also widely available. [4]

  9. Gas holder - Wikipedia

    en.wikipedia.org/wiki/Gas_holder

    A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas (coal gas or formerly also water gas) is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap.
