Absorption is a chemical process by which a gas mixture $($often a gas containing a contaminant, such as acid vapour$)$ contacts a liquid solvent inside a column, and a portion of the gas contaminant is absorbed into the liquid.

In the absorption process below, a column is used to "sweeten" air by removing a toxic contaminant, $H_2{S}_{(g)},$ from the incoming air stream by dissolving it into pure water solvent. The product, called exit gas, must contain no more than $0\mathrm{.}0050\frac{w}{w}\%H_{2}S.$

Air feed:

$40\frac{m^3}{h}$ total flowrate

$20C$ and $1$atm

$0\mathrm{.}048\frac{w}{w}\%H_{2}S$

Water feed:

$110\frac{L}{h}$ total flowrate

$12C$ and $1$atm

Pure $($contains no dissolved $H_{2}S)$

The Question:

Create a complete stream table for this process based on the diagram below. List any assumptions you make to complete it below the stream table.
