Question
![B) The gas stream shown in Table below is fed to an isothermal absorber operating at 90°F and
75 psia. 90% of the n-butane is to be removed by contact with a lean oil stream (sp. gr.= 0.825,
μ=1.2 cp, Mwt=120). Estimate the required number of actual plate and lean oil flow rate if an
inlet rate of 1.1 times the minimum is used.
