  • SYSTEMS AND METHODS FOR GAS SEPARATION USING HIGH-SPEED INDUCTION MOTORS WITH CENTRIFUGAL COMPRESSORS
    Publication number: 20110277629
    Abstract: Systems and processes are provided for gas separation using high-speed induction variable-speed motors to accelerate and decelerate centrifugal compressors suitable for use in pressure swing adsorption (PSA) or vacuum pressure swing adsorption (VPSA) processes.

  • Adsorption control method and controller
    Patent number: 8016914
    Abstract: The present invention provides a method and a control system for controlling an adsorbent bed unit in which an adsorbent bed concentration of an impurity within an adsorbent bed of the adsorbent bed unit is measured. The adsorbent bed concentration is controlled by manipulating the feed cycle time during which an adsorbent bed is adsorbing the impurities to maintain the adsorbent bed concentration at a targeted adsorption bed concentration. The targeted adsorption bed concentration is determined such that the product impurity concentration is maintained at product impurity concentration targets. The method and control system can incorporate a supervisory level of control reactive to product impurity concentration levels and related targets to determine the targeted adsorption bed concentration and a primary level of control that calculates the feed cycle time based upon an error between the measured and targeted adsorption bed concentrations. Proportional integral control can be used for such purposes.

  • Indexing rotary dual valve for pressure swing adsorption systems
    Patent number: 7276107
    Abstract: The present invention relates to a PSA system using an indexing rotary dual valve regulating a stepping mode of operation that controls a variable bed inlet feed flow rate, controllable pressure between feed lines in different beds of the PSA system and varied output flow rate of product gas such as high purity hydrogen gas.

  • Pressure swing adsorption process for co-producing nitrogen and oxygen
    Patent number: 6527830
    Abstract: A pressure swing adsorption process for recovery of a more readily adsorbable component, such as nitrogen, and a larger amount of a less readily adsorbable component, such as oxygen, from a feed gas mixture, such as air, wherein the ratio of nitrogen to oxygen is less than about 3:1 and the ratio of the co-purge:feed gas of the process is maintained at less than about 1.15:1.
