Autoclave waste gas recycle and oxygen addition system

摘要

A system 10 is provided to recycle a waste gas stream 32 of an autoclave 20 to re-use oxygen in the waste gas stream 32 to compliment an oxygen feed stream 19 to the autoclave 20, thereby recycling the waste gas stream 31 to avoid the necessity of having to continuously purge the waste stream 32 of contaminants, while also reducing the amount of oxygen necessary in the feed stream 19 to the autoclave 20. The waste gas stream 32 is also pressurized to be substantially similar in pressure to that of the feed stream 19 to the autoclave 20.
