1. A process for removing contaminants from a feed stream, the process comprising:
- a) performing one or more adsorption steps in an adsorbent bed unit, wherein each of the one or more adsorption steps comprise;
(i) opening one or more actively-controlled feed poppet valves to pass a gaseous feed stream from a feed inlet conduit to an adsorbent bed disposed in an interior region of a housing of the adsorbent bed unit, (ii) exposing the gaseous feed stream to the adsorbent bed to separate one or more contaminants from the gaseous feed stream to form a product stream, and (iii) opening one or more passively-controlled product valves to conduct away the product stream from the interior region in the housing to a product conduit, wherein each of the one or more passively-controlled product valves operate in phase with at least one of the one or more actively-controlled feed poppet valves;
b) performing one or more depressurization steps, wherein each of the one or more depressurization steps comprise conducting away at least a portion of the one or more contaminants in an output stream; and
c) repeating the steps a) to b) for at least one additional cycle, wherein cycle duration is for a period greater than 1 second and less than 600 seconds;
wherein opening the one or more actively-controlled feed poppet valves further comprises linearly moving with a feed actuating mechanism at least one feed valve stem to provide a feed opening between a feed disk element coupled to the at least one feed valve stem and a feed seat that is inserted within a head of the housing of the adsorbent bed unit.

Abstract
Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to treat the feed stream to remove certain contaminants from the stream. In the method and system, active valves may be used with passive valves to manage the flow of the streams through the adsorbent bed units.

18. A swing adsorption system for removing contaminants from a gaseous feed stream, the system comprising:
-
an adsorbent bed unit configured to separate contaminants from a gaseous feed stream and to output a product stream in a swing adsorption process, wherein the adsorbent bed unit comprises; a housing forming an interior region; an adsorbent bed disposed within the interior region; one or more actively-controlled poppet valves, wherein each of the one or more actively-controlled poppet valves is configured to provide a first fluid flow passage through an opening in the housing via the actively-controlled poppet valve between the interior region and a first location external to the interior region; an actuating mechanism coupled to the one or more actively-controlled poppet valves, wherein the actuating mechanism is configured to linearly move at least one active valve stem associated with at least one active disk element for each of the one or more actively-controlled poppet valves to provide an opening between an active disk element coupled to at least one active valve stem and an associated active seat that is inserted within a head of the housing of the adsorbent bed unit; and one or more passively-controlled valves, wherein each of the one or more passively-controlled valves is configured to provide a second fluid flow passage through an opening in the housing via the passively-controlled valve between the interior region and a second location external to the interior region and wherein each of the one or more passively-controlled valves operate in phase with at least one of the one or more actively-controlled poppet valves. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
