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: The present invention relates generally to processes and systems for recovering helium from low helium-containing feed gases (i.e., containing less than about 10 volume % helium and more typically, less than about 5% helium by volume). The present invention more particularly relates to processes and systems for recovering helium from low helium-containing feed gases using temperature swing adsorption (TSA) systems and multiple (e.g. two) stage vacuum pressure swing adsorption (VPSA) systems. In preferred embodiments of the invention, the first stage VPSA system is configured to provide regeneration gas for the TSA system, and/or the VPSA second stage tail gas is recycled to the first stage VPSA system.
