Abstract: A method for controlling two contaminants in a gas stream, comprising a system with two adsorption vessels, and analyzers for determining the concentration of the two contaminants is provided. The method includes purifying a gas stream with a first vessel placed in an adsorption mode and placing a second vessel in a standby mode. Then opening a second purge valve on the second vessel if the concentration of either contaminant is equal to or greater than predetermined threshold levels, thereby allowing a first portion of the purified gas exiting the first vessel to flow through the second vessel and exiting through the second purge valve. Then closing the second purge valve after a predetermined period of time when the concentration of both contaminants are less than or equal to a predetermined threshold level. Then switching the vessels and repeating the process.
