| Abstract: | Sand beds from the t 2k 1 in middle part of the second district in kelamayi oil filed was selected. Static alkali consumption tests were completed at different temperatures (30c, 50c) and solid/liquid ratios 1/2(g/ml), 1/5(g/ml (, 1/10(g/ml) for 8hours, 120 hours and 360 hours respectively. Absolute alkali consumption was calculated for each test. Results show absolute alkali consumption increases while temperature goes up and solid/ liquid ratio decreases. Absolute alkali consumption for sands in NaOH solution is much lager than that in Na 2CO 3. But the relationship between absolute alkali consumption and alkali, temperature and reaction time will be affected by solid/liquid ratios. |
