A feed stream containing C, and C10 hydrocarbons is split into 3 product streams: an overhead fraction, a middle cut and a bottom fraction, whose mole fraction compositions are shown below. Seventy per cent of the C. entering the column in the feed is recovered in the overhead. On the basis of 100 lb-moles/h of feed determine the molar flow rates of the 3 product streams.

streams: an overhead fraction, a middle cut and a bottom fraction, whose
mole fraction compositions are shown below. Seventy per cent of the Cg
entering the column in the feed is recovered in the overhead. On the basis
of 100 lb-moles/h of feed determine the molar flow rates of the 3 product
streams.
