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 41):
The system of  claim 35 , wherein the conditioning circuit further comprises a main heat exchanger configured to vaporize the argon depleted methane rich liquid stream via indirect heat exchange with the feed stream.
