the experimental study and modeling of gravity drainage during water alternative gas injection, wag process, in carbonate rock for one of the iranian off-shore reservoir at lab-scale were carried out. the mechanism of gravity drainage during the wag process, and its contribution to the oil recovery in the fractured carbonate reservoirs were also studied. in the wag process alternatively gas is ...

Understanding the kinetics of gas hydrate formation is essential to model and predict the hydrate formation (or dissociation) process. In the present paper, we investigated the formation of pure propane gas hydrate as a former gas. In this regard, several experiments were conducted to measure the rate of hydrate formation under various pressures (410 to 510 kPa) and temperatures (274 K to 277 K...

co2/ch4 gas separation is a very important applicatable process in upgrading the natural gas and landfil gas recovery. in this work, to investigate the membrane separation process performance, the gas permeation results andco2/ch4 separation characteristics of different prepared membranes (via blending different molecular weights of polyethylene glycol (peg) as a modifier with acrylonitrile-but...

recently, due to the very good market in ethane as a feedstock for petrochemical complexes, thereare some plans to make a deep ethane recovery from the gases produced in iran southern fields. inthis work, the feasibility of different technologies for deep ethane recovery from a specified feed gasproduced in one of the iran southern fields is reviewed. three different processes are selected ands...

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 ...

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...
