Natural gas is often associated with nitrogen and heavy compounds. The Heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. Therefore, heavy components separation can be a necessity and produce useful products. Virtually, all natural gases are containing nitrogen ​​that would lower the heating value of natural ...

The Gas to Gasoline (GTG) process includes conversion of natural, flare, and associated gas into synthetic fuels that can be compositionally upgraded and adjusted into different useful hydrocarbon fuels including gasoline, liquid petroleum gas (LPG), and fuel gas. Commonly, the GTG process involves three stages: 1) Synthesis gas (syngas) production unit 2) Methanol production unit 3) Methanol t...

Advances in technologies for extracting oil and gas from shale formations have dramatically increased U.S. production of natural gas. As production expands domestically and abroad, natural gas prices will be lower than without shale gas. Lower prices have two main effects: increasing overall energy consumption, and encouraging substitution away from sources such as coal, nuclear, renewables, an...

The paper presents an approach to development of the system that supports decision-making for tasks aimed to reduce power consumption of oil-and-gas production enterprise and to enhance the environmental safety of oil and natural gas production. The architecture and operating principles of such a system, as well as the classes of tasks to be solved, are discussed. Adjustment of the system to th...

 Production data analysis techniques have been widely used for estimating reservoir properties such as gas in place and average pressure. Knowledge of this information is crucial for proper reservoir management. The present study discusses the roadmap, challenges and uncertainties for analyzing production data in an Iranian gas-condensate offshore field. This work is an integrated study in...

We consider the relationship between natural gas prices and production in the U.S. resins, agricultural chemicals, cement, and aluminium industries. Overall, our analysis using various tests and regressions does not allow for generalizations about the association between natural gas prices and production across these four energy-intensive industries. Rather, the relationships between natural ga...

hydrogen is seen as one of the important energy carriers of the future with potential to reduce local as well as global warming. the main by-product of the combustion of hydrogen in air is water vapor and trace quantities of oxides of nitrogen. an experiment was conducted to study the impact of hydrogen/natural gas blends on performance, thermodynamic efficiency and exhaust gas emissions in a r...

We use historical and new atmospheric trace gas observations to refine the estimated source of methane (CH(4)) emitted into California's South Coast Air Basin (the larger Los Angeles metropolitan region). Referenced to the California Air Resources Board (CARB) CO emissions inventory, total CH(4) emissions are 0.44 ± 0.15 Tg each year. To investigate the possible contribution of fossil fuel emis...
