An argon enriched air stream contains 49 mass percent na and 30 mass percent ar. this stream enters a distillation column where the distillate consists of argon and nitrogen and the bottoms contains leftover oxygen. nitrogen and argon. the distillate stream contains 99% of the argon fed into the distillation column and flows at a rate of 3062 1bm/hr. the bottoms stream has a mass fraction of 0.693 of nitrogen solve for the flow rate of argon in the distillate stream, the flow rate of the bottoms stream, the mass flow rate of the inlet stream and the composition of oxygen in the bottoms stream. [assume air is a single component, neglect temperature and pressure for your dof analysis, and assume a steady-stale, non-reactive system.]
