摘要： A gas separation process incorporating the invention combines use of an adsorbent having high intrinsic diffusivity with a low pressure ratio PSA cycle. Further enhancements to the process are derived from the use of fast cycles, shallow beds and small particles—especially in a radial bed configuration. The combination of low pressure ratio, high rate adsorbents and fast cycles has been found to result in an unexpected simultaneous reduction in bed size factor (BSF) and power consumption. These benefits have been achieved while minimizing a decline in product recovery through use of the high rate adsorbent. The net result is a significant reduction in product cost.

摘要： An axial flow adsorber apparatus includes a bed of adsorbent material, a barrier in the form of an open-cell material combined with a distribution screen or baffle, graded balls, and an inflatable bladder. The adsorbent bed is the active adsorbent required for a separation process. The barrier combines the open-cell material, which provides uniform retention of all adsorbent material, with the distribution screen, which provides uniform flow and pressure distribution across the bed. The barrier substantially covers a top surface of the adsorbent bed to prevent fluidization of the bed. Graded balls on the barrier uniformly distribute a downward pressure supplied by the inflatable bladder above the balls. The uniform pressure is transmitted through the balls to the barrier to further suppress fluidization. The balls also serve to direct gas flow in the upper end of the vessel and reduce void volume in the apparatus that would trap product gas. The flexible bladder maintains a uniform pressure on the bed while also eliminating a major portion of the void volume in the heads of the adsorber apparatus.
