100mol/min stream of ethane (36 mol % ) and methane is fed into two distillation columns. The first column achleves a separation with an overhead product containing 95 mole percent methane and a bottoms product containing 98 mole percent ethane. The overhead product from the first column is fed to a second distillation column. The bottoms product from the first column is a secondary product of the process. The overhead product from the second column is the desired product which contains 98 mol\% of methane. The bottoms from the second column has a flow rate of 100mol/min and 1s recycled back to the first column. What is the flow rate (mol/min) of the product stream containing 98 mol\%s methane What is the mole froction of methane in the recycle stream? The overhead product from the first column is fed to a second distillation column. The bottoms product from the first bolumn is a secondary product of the process. The overhead product from the second column is the desired product which contains 98 mol\% of metha bottoms from the second column has a flow rate of 100mol/min and is recycled back to the first column What is the flow rate (mol/min ) of the product stream containing 98 mol\% methane What is the mole fraction of methane in the recycle stream
