During tertiary miscible gas injection direct contact between gas and oil can be prevented by water surrounding residual oil. The principal aim of our study is to assess the importance of this waterblocking phenomenon in multicomponent gas injection. We study this process using a multicomponent porescale model. Light components in the gas dissolve in the water and diffuse through the water to r...

Greenhouse gas CO2 emissions to the atmosphere are believed to be the primary reason for the global warming. One effective way to mitigate CO2 emissions is to capture CO2 from post-combustion flue gas in coal-fired power plants. Membrane technology has been widely explored for this application due to its high energy-efficiency. Current membrane materials are often based on poly(ethylene oxide) ...

Measurements of the rate of uptake of soluble gases such as nitrous oxide or acetylene has been used as the basis of a method of cardiac output estimation since 1912. Using theoretical models of single, multiple and rebreathing techniques of cardiac output measurement, we determined the effect of solubility in blood and lung tissue on the changes in the final expired concentration of the gas. D...

Carbon dioxide is one of the major greenhouse gas (GHG) contributors. It is an obligation of the industry to reduce the amount of carbon dioxide emission to the acceptable limits. Tremendous research and studies are reported in the past and still the quest to find the suitable and economical solution of this problem needed to be explored in order to develop the most plausible absorber for carbo...

piroxicam (px), an anti-inflammatory drug, exhibits poor water solubility, dissolution and flow properties. thus, the aim of the present study was to improve the solubility and dissolution rate of px by freeze drying technique using dimethylformamide (dmf), chloroform and water as co-solvent system. the prepared crystals containing px were evaluated for dmf and chloroform solvent residual by ga...

Silver containing nanocomposites receive increasing attention as antibacterial coatings. In this study we report on production of such materials using combination of gas aggregation sources of Ag nanoparticles and plasma enhanced chemical vapour deposition performed in HMDSO/O2 working gas mixtures. The main attention is devoted to the investigation of solubility of Ag nanoparticles in water in...

The Oil & Gas Journal, in 2004, states that CO2 flooding is the fastest-growing enhanced oil recovery technique in USA, and production derived from CO2 projects has more than tripled from 50,000-Barrels/day to 200,000-Barrels/day. Cyclic injection of CO2 and N2 combines environmental benefits attendant to reducing CO2 concentrations in the atmosphere and economic benefits realized through impro...
