A gas stream containing $40\mathrm{.}0$ mole$\%$ hydrogen, $35\mathrm{.}0\%$ carbon monoxide, $20\mathrm{.}0\%$ carbon dioxide, and $5\mathrm{.}0\%$ methane at $15\backslash$deg C and at a constant absolute pressure of $35\mathrm{.}0$ atm. Gas enters the cooler at $120$ m$3/$min and upon leaving the cooler is fed to an absorber$,$ where it is contacted with refrigerated liquid methanol. The pure methanol is fed to the absorber at a molar flow rate $1\mathrm{.}2$ times that of the inlet gas and absorbs essentially all of the CO$2,98\%$ of the methane, and none of the other components of the feed gas. The gas leaving the absorber$,$ which is saturated with methanol at $15\backslash$deg C$,$ with a partial pressure of CH$3$OH at $1000$ pa is fed to a reactor for further processing.

calcualte the volumetric flow rate of the gas leaving the absorber
