Batch experiments were conducted to determine the effects of variables such as pH, aeration velocity, gas/liquid (G/L) ratio, ambient temperature and aeration (strip) time on NaCN recovery.
As the philosopher Mircea Eliade wrote half a century ago, "The modern West is the first culture that has managed to strip time and space of all sacredness and to produce a fully practical, efficient, and profane world".
An old Eurovision trick, this: the mid-song strip, timed to coincide with musical fatigue.
Mr. Viertel's book strips "Time and Again" down to its barest plot, adorned with some confused reflections on the birth of feminism.
Optimal GS-SSF conditions of initial gas stripping time, gas stripping temperature, fermentation time, and particle thickness were 10 h, 35°C, 28 h, and 0.15 cm, respectively.
Fermentation conditions that might affect GS-SSF performance (including initial gas stripping time, gas stripping temperature, fermentation time, and particle thickness) were also investigated in the present study.
According to the above analysis, the optimal initial gas stripping time was determined as 10 h after inoculation during SSF.
The initial gas stripping time during SSF should be the balance of the capital cost of the stripping operation and the ethanol yield or the ethanol stripping efficiency.
The optimal initial gas stripping time, gas stripping temperature, fermentation time, and particle thickness of GS-SSF were 10 h, 35°C, 28 h, and 0.15 cm, respectively, and the corresponding ethanol stripping efficiency was 77.5%.
In the present study, the evaluation of initial gas stripping time during GS-SSF for conversion of SSS into bioethanol was carried out in shake flasks.
Figure 4a shows the decrease in butanol concentrations in the model solution with different types of media over 5 h vacuum stripping time, showing that the designed vacuum stripping system can effectively remove the butanol.
