temperature for the condensor. 100 gmol/min of a gas stream containing 30 mol% ethane (C,H,) and 70 mol% methane (CH,) is fed to a distillation column, where it is sepa- rated into an overhead product containing 90 mol% methane and a bot- toms product containing 98 mol% ethane. A customer wants to purchase a product that contains 97% methane. To produce this, the overhead from the column described above is sent to a second column. The overhead from the second column is the desired product, and the bottoms product, which has a flow rate of 100 gmol/min, is recycled back to the first col- umn. Calculate the flow rate of the final product and the composition of the recycled stream. Calculate the fractional recoveries of methane and ethane in their corresponding product streams,
