The feed to a fractionating column is fed at a rate of 100,000kgh1 and is separated into an overhead product and a bottom product. The analysis of the feed is as follows: The overhead product contains all the LTP most of the iC5, 1% of the nC5 in the foed but no HTP. The bottom product consists of 5% of iC5. Calculate the compositions and flow rates of the overhead and bottom streams. All percentages are reported in weight per cent. Hint: Draw a well labelled diagram and carry out a degree of freodom analynis prior to solving the problem. (25 marks)
