![]() The fiscal effects of natural gas volume and mass flow measurement and calculations.The solids block gas fittings, and the water is corrosive. Water, together with hydrocarbons, favors the generation of solids, in particular during the decompression of gas from high-pressure pipelines. ![]() Water dew point is the temperature at which water condenses out.The accumulation of liquid in the pipelines can lead to a plug flow and may destroy the compressors in the pumping station Liquid phase is produced in the gas pipeline if the product temperature falls below the hydrocarbon dew point. Hydrocarbon dew point, which is a temperature at which higher hydrocarbons condense.Hydrogen sulphide and mercaptans are partially present as natural compounds and sometimes are mixed with the gas together with other sulphur compounds as odorants. It is the major variable when defining the price. Upper calorific value, which is the latent energy content of a gas that is released during combustion.Pipeline gas metering stations are designed for simultaneous, continuous analysis of the quality and quantity of natural gas being transferred in a pipeline, as follows: ![]() Nor does it cover the different standards of particular flow measuring devices, such as AGA-3 for differential pressure measurement AGA-7 for turbine meters and vortex meters and AGA-8 which provides equations to compute compensation factors for measured rates. This article looks at pipeline natural gas metering station design but does not address the equations and empirical data used to calculate gas flow rates and volumes for custody transfer.
