Problem 2: A) In the feedstock preparation of a plant manufacturing natural gasoline, isopentane is removed from butane-free gasoline. Assume for purposes of simplification that the process and components are as shown in the Figure below. What fraction of the butane- free gasoline is passed through the isopentane tower? Assume the process is in the steady state and no reaction occurs. 4 isopentone side stream Ti-CsHiz 100% De- butonizer Iso- pentone tower Overall system boundary -CH 2 100% 100 kg Butone free feed -Csiz 8090 To naturales oline piante 90% n-Chez 10% i-CsHiz i-CsHZ 20% B) Find distance d for the U tube.
