In the present disclosures, a mixed gas containing monosilane is discharged from a semiconductor production device (1). A pump unit (2) sucks the mixed gas discharged from the semiconductor production device (1), and sends the mixed gas to a later-stage silane gas processing unit (20). Argon gas is used as a purging gas in the pump unit (2). The silane gas processing unit (20) process the mixed gas that contains at least monosilane and argon and that is discharged from the semiconductor production device (1) through the pump unit (2), and isolates, recovers, and recycles the monosilane. A noble gas processing unit (30) isolates, recovers, and recycles the argon from the mixed gas. The argon recovered by the noble gas processing unit (30) is used as the purging gas of the pump unit (2).
