摘要： A vacuum swing adsorption process for separating a feed gas mixture into a more strongly adsorbable component and a less strongly adsorbable component in a process employing two vacuum pumps and three adsorbent beds containing an adsorbent selective for the more strongly adsorbable component using countercurrent depressurization and cocurrent ambient feed repressurization simultaneous with product end to product end pressure equalization and a common-shaft machinery arrangement which allows the expansion energy contained in the countercurrent depressurization and cocurrent ambient feed repressurization streams to be recovered and utilized to reduce overall process power consumption. Addition of three valves and an expander element will also allow expansion energy in the product purge and pressure equalization streams to be recovered. Oxygen product can be recovered from air at low cost using the process.

摘要： Method of operating a pressure swing adsorption system having a plurality of parallel adsorber vessels and a plurality of valves and gas manifolds adapted to introduce gas into each adsorber vessel and withdraw gas from each adsorber vessel in a cyclic series of sequential process steps. A leaking valve may be identified by (1) determining a value of an operating parameter that is a function of the mass of gas provided to a receiving adsorber vessel or withdrawn from an adsorber vessel during a selected process step, portion of a process step, or series of process steps; (2) determining the deviation of the value of the operating parameter from a predetermined reference value; and (3) using the magnitude and direction of the deviation to determine whether any valves are leaking.
