A three-theoretical-stage batch stripper (one stage is the boiler) is charged to the feed tank (see Figure 13.8) with 100 kmol of 10 mol% n-hexane in n-octane mix. The boilup rate is 30 kmol/h.
If a constant boilup ratio (V/L) of 0.5 is used, determine the instantaneous bottoms composition and the composition of the accumulated bottoms product at the end of 2 h of operation.
