    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: A pressure swing adsorption (PSA) system for purifying a feed gas is provided. The PSA system may have a first adsorber bed and a second adsorber bed, each having a feed port, a product port, and adsorbent material designed to adsorb one or more impurities from the feed gas to produce a product gas. The PSA system may also have a network of piping configured to direct the feed gas to the feed ports of the adsorber beds and direct the product gas to and from the product ports of the adsorber beds. The network of piping may also be configured to transfer gas between the first adsorber bed and the second adsorber bed during a pressure equalization step and a purge step. The PSA system may also have a first valve configured to direct flows of the feed gas and the product gas through the network of piping. The PSA system may further have a first orifice configured to regulate a flow rate of gas between the first adsorber bed and the second adsorber bed during at least one of the pressure equalization step and the purge step.
