residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. in this study experimental tests in a glass micromodel w...

The method of antisolvent application used during the fabrication solution-processed lead halide perovskite layers influences their microstructure, stoichiometry and consequently, photovoltaic performance.

In recent years, the feasibility of utilizing gas hydrates in industrial systems draws much attention as a subject of engineering studies. Despite the suggested applications for gas hydrate in transportation and storage of natural gas, desalination of water, etc., there have been few applied industrial experiences with gas hydrates. There are several patents and papers on promotion of gas hydra...

Gas hydrate formation in production and transmission pipelines and consequent plugging of these lines have been a major flow-assurance concern of the oil and gas industry for the last 75 years. Gas hydrate formation rate is one of the most important topics related to the kinetics of the process of gas hydrate crystallization. The main purpose of this study is investigating phenomenon of gas hyd...

pyrolysis of low density polyethylene (ldpe) by equilibrium fluid catalytic cracking (fcc) was studied in a stirred reactor under different process parameters. in this work, the effect of process parameters such as degradation temperature (420-510°c), catalyst/polymer ratio (0-60%), carrier gas type (h2, n2, ethylene, propylene, ar and he), residence time and agitator speed (0-300 rpm) on the c...

hydrates are crystalline compounds similar to ice, with guest molecules like methane and ethane trapped inside cavities or cages formed by the hydrogen bounded framework of water molecules. these solid compounds give rise to problems in the natural gas oil industry because they can plug pipelines and process equipments. low dosage hydrate inhibitors are a recently developed hydrate control tech...

results the modeling results showed that for the gas recovery starting in 2000 and 2015, the power generation would be 2,354 and 830 mw, respectively. in fact, the 15-year difference in gas extraction made a 200% difference. based on the results, from 2000 to 2100, 558 m3/hour of methane would be extracted, which would be equivalent to 2,354 mw energy. subsequently, the emission of 93,721,837 t...
