Exergy of natural gas flow in Iran's natural gas fields

Natural gas flow has a valuable pressure exergy which is currently destroyed in throttling valves at exit of the gas fields. In the current study, this pressure exergy has been calculated for an actual case. Exergy analysis was based on actual condition of the Shanol gas field, which is situated in Iran, in the summer. It is assumed to be a good representative of Iran's whole gas fields. Exergy ...

Evaluation research on performance of permeability and fracture in Sulige gas field by new method

Tight gas is the most available alternative unconventional natural gas in China. Its potential is huge and the Sulige gas field is the biggest one. However, there are many urgent development problems to be solved, and evaluating well performance is of one of them. Low permeability, strong stress sensitivity and hydraulic fracturing make it difficult to predict well performance. Evaluating the ...

Restriction of gas losses in an overpressurised CO 2 reservoir using gel technology

The overpressurised CO 2 field Bečej (Serbia) was explored in 1951. At the end of 1968, an uncontrolled gas blowout of Bč-5 well lasted 209 days resulting in 35 bars pressure drop in the reservoir until 2007. Hence, the substantial loss of reserve (> 17 billion m 3 ) became a critical issue of the operator. Environmental friendly chemicals should be used only for well rehabilitation. ...

Behavior of Flame Spread Downward over Thick Wood Sheets and Heat Transfer Analysis

To investigate the flame spreading mechanism over charring materials under natural convection, wood sheets from 0.9 to 3 mm thickness have been chosen. The variation of mean flame spread velocity V with thickness is measured. Typical flame shapes over the wood surfaces are recorded using CCD. The temperature fields in the gas phase are examined by a set of fine thermocouples. On the basis of the ...

Verification of Wind-Driven Volatilization Models

Abstract Mass-transfer processes of paramount importance, such as reaeration and volatilization, occur at the air–water interface. Particularly, volatilization is intensively studied because it can be a relevant removal process for toxic contaminants from flowing and standing surface waters. The paper provides a comparison among predictive equations available from literature for standing waters ...

Comparison of greenhouse gas analyzers -measurements using photoacoustic, laser, FTIR analyzers and gas chromatography

In the last decades, several technologies have been developed to measure greenhouse gas (GHG) concentrations and fluxes. We compared six devices using different measurement technologies: two gas chromatographic systems with a barrier discharge ionization detector (GC-BID) and an electron capture detector (GC-ECD), respectively, a portable GHG analyzer based on laser absorption, a photoacoustic ...

Quick laboratory analysis of gas condensate in produced water

Abstract Often there is a need for quick field measurement of gas condensate concentration in produced water, such as when performing process optimization, water treatment verification and routine process monitoring. Rigorous laboratory analysis methods such as gravimetric oil and grease measurements or gas chromatographic methods are not sufficiently sensitive to process changes and/or do not ...

Hydrate risks and prevention solutions for a high pressure gas field offshore in South China Sea

YC13-4 gas field is located in the west of the South China Sea, where the seawater depth is around 90 m, and the average surface temperature is 26.2°C, while the minimum temperature at seabed is 18.9°C. Subsea wellheads are designed for gas production. In this paper, the risks of hydrate formation during drilling, well testing and gas production are analysed under different operation conditions. ...

The design of electrostatic precipitators by use of physical models

This paper describes how physical models can be successfully employed in the design of Electrostatic Precipitators (ESP). The development of the computational power of personal computers has made possible the development of mathematical models of complex systems, like ESP, that can be used at relatively low cost. These mathematical models simulate the non linear coupling of the different physical ...

Activated Carbon

Activated carbon, also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. The word activated in the name is sometimes replaced with active. Due to its high degree of micro-porosity, just 1 gram of activated carbon has a surface area in excess ...
