Abstract:
The development of the oil and gas complex is one of the priority areas of the Azerbaijan economy. Oil and gas are among the most competitive Azerbaijan goods and are in high and stable demand from global consumers. Therefore, increased attention is paid to product quality. One of the methods for quality control of petroleum products is gas chromatography. Today it is a widely used physical and chemical research method. The capabilities of a gas chromatography are mainly determined by the enormous separating power of the chromatographic columns and the characteristics of the detectors. If the

For determining 22 volatile organic compounds in the atmospheric air, the operating modes of the gas chromatographic complexes «chromatography-mass spectrometer — two-stage thermodesorber» and «gas chromatograph with 2 FID — static headspace analysis sampler» are optimized. The modes provide the values of the separation coefficients of the chromatographic peaks in the range of 1.5 ÷ 21. It has been experimentally established that the highest desorption efficiency of volatile organic compounds is registered when the sample is concentrated into Tenax TA sorption tubes.

Introduction. Liquefied hydrocarbon gases (LHG) are widely used in various fields. The main components of LHG are: propane, isobutane and n-butane, which are not only combustible, but also explosive gases capable of detonation combustion. The detection of LHG in the air is a very urgent task in expert studies. To determine the component composition of various flammable liquids, for the purpose of their identification, chromatographs equipped with a capillary quartz column with a phase that allows detecting saturated hydrocarbons of the homologous series from pentane to pentatetracontane inclus

During the synthesis of isopropyl alcohol by the acetone hydrogenation reaction, it is necessary to control the content of impurities in the hydrogen used, since its purity determines the quality of the product, and impurities of CO and CO2 are catalytic poisons for this reaction. At the «Omsky Kauchuk» plant, the purity of hydrogen is determined by gas chromatography using two different chromatographs — laboratory and flow. A comparison of the results of the parallel determination of hydrogen purity revealed a discrepancy of about 10 % wt., while the flow chromatograph did not detect impuriti

An alternative sampling technique for fingerprint analysis of complex mixtures of petroleum-based products is presented. Fingerprint chromatograms of the volatile organic compounds (VOCs) for class 0-5 accelerants can be readily obtained using the recently developed inside needle capillary adsorption trap (INCAT) device. The concentration of VOCs from the static headspace of these complex mixtures, onto the adsorbing carbon coating of the INCAT device, avoids some problems associated with conventional headspace gas chromatography (HS-GC). The INCAT sampling method is a solventless extraction t

This research contributes to worldwide efforts to miniaturize one of the most powerful and versatile analytical tools, gas chromatography (GC). If a rapid, sensitive and selective hand-held GC system is realized, it would have a wide range of applications in many industries and research areas. As a part of developing a hand-held GC system, this research focuses on the separation column, which is the most important component of a GC system. This thesis describes the development of a miniature separation column that has low thermal mass and an embedded heating element for rapid thermal cycling.

Therefore, the energy content of the gas at a delivery point may differ significantly from its associated system chromatograph. On lean burn engines with tight emission controls, changes in the energy content of the fuel gas can significantly alter the amount of air required to maintain emissions compliance. A reliable, low cost, and fast responding energy meter is desired for both scenarios described. Four Energy Meters are evalua

Abstract:
This report describes the tests results carried out on five natural gas gross calorific value analyzers depending on the calibration model. Three analyzers were conventional gas chromatographs. Two analyzers were new generation gas chromatographs. Twenty-three gas blend were used for this study including three calibration gas blend. Therefore, the report enables the most suitable linear calibration model to be chosen, in order to minimize gross calorific value measurement errors with respect to methods.

Abstract:
In natural gas production and processing applications, methanol is commonly injected into natural gas streams containing water to prevent the formation of hydrates in gas lines and subsequent equipment damage. However, gas chromatographs (GCs) at field sites are typically not equipped to identify or measure methanol, and unless excess methanol is expected to carry over into a gas stream, samples sent to a laboratory are not likely to be analyzed for methanol. As a result, the potential exists for errors in gas property determination, particularly in heating value and sound speed. A previous PR

Abstract:
In 1998, a multi-year project to develop a working prototype instrument module for natural gas energy measurement was initiated. The module will be used to retrofit a natural gas custody transfer flow meter for energy measurement, at a cost an order of magnitude lower than a gas chromatograph. Development and evaluation of the prototype energy meter in 2002-2003 included: (1) refinement of the algorithm used to infer properties of the natural gas stream, such as heating value; (2) evaluation of potential sensing technologies for nitrogen content, improvements in carbon dioxide measurements, an
