Gas networks simulation or gas pipeline simulation is a process of defining the mathematical model of gas transmission and gas distribution systems, which are usually composed of highly integrated pipe networks operating over a wide range of pressures. Simulation allows to predict the behaviour of gas network systems under different conditions ...
A recent innovation is to combine the experimental method with theoretical. If the composition of the gas is analyzed by a C6+ GC, and a dewpoint is experimentally measured at any pressure, then the experimental dewpoint can be used in combination with the GC analysis to provide a more exact phase diagram.
Natural gas poses a unique problem in terms of moisture content analysis because it can contain very high levels of solid and liquid contaminants, as well as corrosives in varying concentrations. Measurements of moisture in natural gas are typically performed with one of the following techniques: [8] color indicator tubes; chilled mirrors
Gas chromatography and isotope analysis are the known methods that are used for determining the characteristics of hydrocarbon material samples. [36] The method is also named oil fingerprinting, and uses data about the chemical and isotope composition of liquid and gas flow for each contribution that is collected. Samples from each contributing ...
The separator divides the flow from the well into the streams of individual products which typically are oil, gas and water, but may include natural-gas condensate. Contamination may also be removed and fluid samples collected. This helps to allocate individual flow rate contributions, but the method has uncertainties.
A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
While the analysis admits that increasing LNG exports would generate revenue and create jobs across the natural gas supply chain, it simultaneously holds that the average American household would ...
One of the most widely used methods for headspace analysis is described by the United States Environmental Protection Agency (USEPA). Originally developed by the R.S. Kerr USEPA Laboratory in Ada, Oklahoma as a "high quality, defendable, and documented way to measure" methane, ethane, and ethene, [7] [8] RSKSOP-175 is a standard operating procedure (SOP) and an unofficial method employed by ...
