... disk apparatus. The effects of disk rotational speed, initial citric acid concentration, and temperature on the effective diffusion coefficient of citric acid were examined. Using various citric acid concentrations (1, 2, 5, 7.5 wt the diffusion coefficient of citric acid was calculated at 25, 40, 50°C...

The laboratory results showed that, during low velocity displacement of methane by flue gas in a homogeneous linear sand- pack, molecular diffusion has a dominating effect on the recovery of marketable methane. Reasonable values of molecular diffusion coefficient for different gas/gas...

..., condensing and non-condensing conditions. The oil production rates in the data set span a 30,000 fold range. The correlation only requires the raw bitumen viscosity and a grain (or pore) size parameter and provides a correlation coefficient R2 of 0.974 (R2=1 indicates a perfect correlation). Consequently...

... rate when ethane was used. This was surprising, because the viscosity of bitumen saturated with ethane was about one-fifth of that for CO2, and the drainage rate using ethane should theoretically be 2.2 times that of CO2. They tried to explain this phenomenon by stating that the dispersion coefficient...

... formations. The physics of transport and sequestration of CO2 for different CO2 injection processes in a pore-level scale is first described. These pore-level events are then related to core-scale (grid- scale) coefficients using an advanced upscale theory. At the pore-level, a unit cell consists...

It is found that the gas-coal system behaves distinctively in the presence of kinetics and that the coal matrix heterogeneities generate multiplicative non-trivial effects on transport. Consequently, average gas concentration field...
