The enriched CO2 gathered at the leading edge of displacement, however due to the insufficient length of core, CO2 breakthrough early from production well and generated a communication path before it enriched enough to achieve fully miscible flooding.
Open image in new window Fig. 6 Effect of column length on the breakthrough curves for adsorption of nickel at different bed porosity.
In long slim tube with length of 1,528 cm, gas breakthrough later at 0.92 PV and ultimate oil recovery is 90.45 % at 1.2 PV.
In short slim tube with length of 101 cm, gas breakthrough early at 0.82 PV, then oil recovery increases slightly and ultimate oil recovery is 74.20 % at 1.2 PV.
The effect of operating conditions, including temperature, feed concentration, column length and diameter, on the performance of breakthrough curves were determined.
This is an important breakthrough, as the length of the synthesized SWNTs, and their high alignment, makes their electrical characterization and device fabrication much more accessible than ever before.
Collected information included: gender, age, diagnosis, cost of hospitalization (including pharmacy, chemistry laboratory, and hemodialysis), length of hospital stay, renal toxicity, hepatotoxicity, breakthrough fungal infections, hemodialysis (HD) requirements, reason for HD, and modification of antifungal prophylaxis.
This was a moment of breakthrough.
We saw a number of breakthrough performances.
That's a kind of breakthrough".
The rates of breakthrough infection were comparable.
