Minimum Liquid Rate for Absorption Column Solution

Follow our step by step solution on how to calculate Minimum Liquid Rate for Absorption Column?

FIRST Step Consider the formula

L smin = G s \cdot \frac{Y N+1 - Y 1}{(\frac{Y N+1}{α}) - X 0}

Next Step Substitute values of Variables

∴

L smin = 9mol/s \cdot \frac{0.8 - 0.1}{(\frac{0.8}{1.5}) - 0.0099}

∴

L smin = 9 \cdot \frac{0.8 - 0.1}{(\frac{0.8}{1.5}) - 0.0099}

Next Step Evaluate

∴

L smin = 12.0359167038146mol/s

LAST Step Rounding Answer

∴

L smin = 12.0359mol/s
