Question:
You need to temporarily increase the feed rate to an existing column without flooding. Since the column is now operating at about \(90 \%\) of flooding, you must vary some operating parameter. The column has \(0.4572 \mathrm{~m}\) tray spacing, is operating at \(1.0 \mathrm{~atm}\), and has a flow parameter of
\[ \mathrm{F}_{\mathrm{lv}}=\frac{\mathrm{L}}{\mathrm{G}}\left(\frac{ho_{\mathrm{v}}}{ho_{\mathrm{L}}}\right)^{0.5}=0.05 \]
The column is rated for a total pressure of \(10 \mathrm{~atm} . \mathrm{L} / \mathrm{D}=\) constant. The relative volatility for this system decreases slowly as pressure increases. The condenser and reboiler can easily handle operation at a higher pressure. Downcomers are large enough for larger flow rates. Will increasing the column pressure increase the feed rate that can be processed? It is likely that
Determine the value of the exponent for this situation. Use the ideal gas law.
