摘要： 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.

摘要： A cyclic adsorption process is provided having pressurization and depressurization steps and driven by one or more centrifugal machines operating under acceleration and deceleration conditions wherein the deceleration rate of the machine is controlled to minimize power consumption and maximize the efficiency of the process. The operating speed of the centrifugal machine during deceleration is matched to the measured ratio pressure conditions so that the centrifugal machine arrives at its minimum operating speed near the point required to begin acceleration.

摘要： The present invention relates to a method and control system to control the speed of a centrifugal compressor operating within a vacuum pressure swing adsorption process to avoid an operation at which surge can occur and directly driven by an electric motor that is in turn controlled by a variable frequency drive. In accordance with present invention an optimal speed for operation of the compressor is determined at which the compressor will operate along a peak efficiency operating line of a compressor map thereof. This speed is adjusted by a feed back speed multiplier when the flow or other parameter referable to flow through the compressor is below a minimum and a feed forward multiplier during evacuation and evacuation with purge steps that multiplies the feed back multiplier to increase speed of the compressor and thereby avoid surge.
