Abstract:
A system and method for argon and nitrogen extraction from a feed stream comprising hydrogen, methane, nitrogen and argon, such as tail gas of an ammonia production plant is provided. The disclosed system and method provides for nitrogen-argon rectification and the methane rejection within a column system comprised of at least one distillation column. Nitrogen and argon are further separated and to produce liquid products. An argon stripping column arrangement is disclosed where residual argon is further removed from the methane-rich fuel gas and recycled back to the feed stream.

Claim (Index 34):
The system of  claim 27 , further comprising a hydrogen stripping column configured to receive the argon enriched stream and strip hydrogen from the argon enriched stream to produce a hydrogen-free argon enriched stream, wherein the hydrogen-free argon enriched stream is directed to the distillation column arrangement as the argon enriched stream.
