The heavier components have to be removed from a gas stream by absorption$.$ The column operates at $2760$ kPa $.$ The entering liquid is high molecular mass oil. Estimate the compositions and flow rates of the exit streams by using the method given above. It can be assumed that the A and $S$ values can be based on the entering values of $L$ and $V($given in the table below$),$ and that the $K$ values can be determined at the average top and bottom temperatures of the absorber$.$ There are six stages in the column and hence $N=6.$
