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. 2. The method of claim 1, wherein the using includes using a pressure swing absorption apparatus that includes at least one rotary distributor valve for each group of beds. 3. The method of claim 2, wherein the at least one rotary distributor valve per group provides fluid interconnections to first and second ends of the absorbent material of the beds within a group for a feed stream, a product stream, and a purge stream, and the at least one rotary distributor valve per group providing fluid interconnections to the absorbent material of the bed in another group for a blow-down stream and a purge supply stream. 4. The method of claim 1, further comprising varying a cycle frequency so as to achieve at least one of a predetermined purity, recovery, or flow rate of the first component or the second component. 5. The method of claim 1, wherein each group of beds has an equal number of beds. 6. The method of claim 1, wherein the controlling excludes using a control valve or adjustable orifice to control flow rate. 7. The method of claim 1, wherein the controlling step includes adjusting the phase angle difference from zero degrees to forty-five degrees. 8. The method of claim 1, wherein the at least four beds rotate with a same rotational speed. 9. The method of claim 1, wherein the absorbent material of each of the at least four beds is identical. 10. A pressure swing absorption apparatus, comprising: 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; anda 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. 11. The pressure swing apparatus of claim 10, wherein the at least four rotating beds are each configured with a feed port that receives a feed gas mixture, and a product port that outputs a first component of the feed gas mixture. 12. The pressure swing apparatus of claim 10, wherein the at least four beds are configured to separate the feed gas mixture into the first component and a second component. 13. The pressure swing apparatus of claim 12, wherein the absorbent material more readily absorbs the second component under an increase in pressure relative to the first component which is less readily absorbed under the increase in pressure. 14. The pressure swing apparatus of claim 10, further comprising at least one rotary distributor valve for each group of beds. 15. The pressure swing apparatus of claim 14, wherein the at least one rotary distributor valve per group provides fluid interconnections to first and second ends of the absorbent material of the at least four beds within a group for a feed stream, a product stream, and a purge stream, and the at least one rotary distributor valve per group providing fluid interconnections to the absorbent material of the bed in another group for a blow-down stream and a purge supply stream. 16. The pressure swing apparatus of claim 10, wherein each group of beds has an equal number of beds. 17. The pressure swing apparatus of claim 10, wherein the control system excludes a control valve or adjustable orifice to control flow rate. 18. The pressure swing apparatus of claim 10, wherein the control system includes a computer, and a drive system, controlled by the computer, that rotates the at least four beds at the same rotational speed, and the computer and drive system individually control the phase of each of the four beds. 19. The pressure swing apparatus of claim 10, wherein the control system includes a chain, belt, or synchronous belt drive system that drives a rotation of the at least four beds. 20. The pressure swing apparatus of claim 19, wherein the control system includes two or more idler cogs or sheaves that adjust a slack chain or slack belt in order to change a rotational speed of some of the at least four beds. 21. The pressure swing apparatus of claim 10, wherein the absorbent material of each of the at least four beds is identical.
