摘要：
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.
摘要（中）：
提供了一种用于控制气流中的两种污染物的方法，该方法包括具有两个吸附容器的系统和用于确定两种污染物浓度的分析仪。 该方法包括用置于吸附模式的第一容器提纯气流并将第二容器置于待用模式。 然后，如果污染物的浓度等于或大于预定的阈值水平，则打开第二容器上的第二净化阀，由此允许离开第一容器的净化气体的第一部分流过第二容器并通过第二容器流出 清洗阀。 然后在两个污染物的浓度小于或等于预定阈值水平的预定时间段之后关闭第二净化阀。 然后切换容器并重复该过程。
