A waste stream from your company is composed of 60% He and 40% Argon. This waste stream is used as inerts in a batch reactor and is currently vented to the atmosphere. A new engineer proposes separating the helium from this waste stream to sell or use elsewhere in the plant. The ideas is to use glass, which is impermeable to Ar to purify the helium Consider a rectangular piece of glass (SiO2) separating the Argon/He waste stream from pure He. The waste stream is at 100 bar on one side of the glass, and the pure helium is on the other side at 1 bar. The entire system operates isothermally at 320K. The glass is 1 m wide by 2 m high by 1 cm (0.01 m) thick, How much pure helium, in units of pg, is purified in 24 hours? Note Use a value of 4 g/mol for the molecular weight of He. . 1 ug = 100g 40 mol% Ar 60 mol% He 100 bar 320K 100 mol% He 1 bar 320 K 1 cm im O AOS
