Rotating Bed Device for the Separation by Adsorption of at Least One Constituent of a Gaseous Mixture

摘要

A pressure swing absorption apparatus, including: at least four beds that each include an absorbent material, wherein the at least four beds are configured to rotate and are grouped such that members of one group only have fluid interconnections with members of another group; and a control system that controls a flow rate of a fluid communication between at least two of the beds by adjusting a phase angle difference between the at least two of the beds.

1. A method, comprising:
using a pressure swing absorption apparatus to separate a feed gas mixture into at least a first component and a second component, wherein
the first component is more readily absorbed under an increase in pressure relative to the second component which is less readily absorbed under the increase in pressure over an absorbent material included in the pressure swing absorption apparatus, andthe pressure swing absorption apparatus includes at least four rotating beds of the absorbent material, the at least four beds are grouped such that members of one group only have fluid interconnections with members of another group; andcontrolling a flow rate of a fluid communication between at least two of the beds by adjusting a phase angle difference between the at least two of the beds.
