Extracted text: A solvent is recovered from a waste gas in a purification system with recycle. The gas feed contains 0.4 moi fraction of the solvent in an inort gas. The recovery unit gas effiuent is to have a composition of 0.06 mol fraction solvent. The purification unit can remove 63% the solvent fed to L. What is the recycle ratio for the process, that is, how many moles of recycle are there per mole of waste gas fed to the process? report your answer to 1 significant decimal point. (if you compute the answer as 1.2345 then record 1.2)
