using natural gas as a clean, plentiful and inexpensive source of energy in recent years has progressively increased in iran. pipelines are the most common system to transport natural gas from field to different regions of iran. these pipelines always pose risks to surrounding population and environments. the aim of this study was to assess the potential health, safety, and environment risk of ...

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 ...

This study investigates the use of activated carbon for the odorant removal from natural gas to be used for synthesis gas production for fuel cells. The odorants used in this study were dimethyl sulfide, tetrahydrothiophene, methyl mercaptan, and t-butyl mercaptan. It was concluded that only physical adsorption is contributing towards removal of sulfur species at lower temperatures, whereas the...

Sir Humphry Davy witnessed the first chlorine hydrate crystallizing in 1811. Couple of century later his discovery, natural gas hydrates has begun to play an important role in energy business. From being a mere chemical curiosity, they have proven to be a nuisance for the natural gas industry. The problem of hydrate induced blockage in “wet gas” flow systems has been widely reported and became ...

We quantify natural methane hydrate reservoirs by generating synthetic seismic traces and comparing them to real seismic data: if the synthetic matches the observed data, then the reservoir properties and conditions used in synthetic modeling might be the same as the actual, in-situ reservoir conditions. This approach is model-based: it uses rock physics equations that link the porosity and min...
