Claim:
1. An apparatus for the recovery of a process gas used in the production of an object from at least one production tool, comprising; (a) at least one production tool used in the production of an object comprising an input line for introducing a process gas, the process gas having a concentration of a first gas that is greater than or equal to a first concentration, wherein the at least one production tool is in electrical communication with a process controller; (b) an effluent line in flow communication with the at least one production tool, wherein the effluent line removes a spent process gas after the object is processed in the at least one production tool; (c) a recovery line operationally configured to deliver at least a portion of the spent process gas to a treatment line; (d) the treatment line comprising a purifier wherein the spent process gas is treated in the purifier to provide a recovered process gas; (e) a purification bypass line operationally configured to deliver at least a portion of the spent process gas to the input line without an intermediate purification process; and (f) an end product gas line configured for introducing the recovered process gas into the at least one production tool via the input line.
