1. An adsorber comprising:
- a) an adsorber body, wherein the adsorber is a temperature swing adsorption apparatus or pressure swing adsorption apparatus and an adsorber bed is disposed within the adsorber body;
b) a first head engaged with said adsorber body;
c) a first conduit extending from outside said head to at least partially through said head; and
d) a plurality of valves, wherein the plurality of valves comprise a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the adsorber body, wherein at least one of said plurality of valves is a poppet valve comprising a disk element connected to a valve stem element and wherein the distance during operation between a poppet valve disk element flat surface in the fully open position and an adsorber bed surface is between 5% and 200% of the disk element diameter.

Abstract
An adsorber with minimal dead volume especially suited to reverse-flow applications comprises: a) an adsorber body; b) a first head engaged with said adsorber body; c) a first conduit extending from outside said head to at least partially through said head; and d) a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the adsorber body. The adsorber is especially suited for use in a process for swing adsorption separation processes.

15. An adsorber comprising:
-
a) an adsorber body partially enclosing an adsorptive region comprising two substantially opposing open ends; b) a first head capping one end of the adsorber body; c) a second head capping the opposing end of the adsorber body; d) a fixed bed comprising a region proximal to the first head, a region proximal to the second head and a central region disposed therebetween, which fixed bed is disposed within the adsorber body and comprises solid material capable of promoting adsorption of one or more components of a gas stream; e) at least one gas stream inlet associated with the first head opening a pathway through the first head and into the adsorber body and at least one gas stream outlet associated with the second head opening a pathway from the adsorber body and through the second head; f) at least one inlet poppet valve controlling the gas stream inlet and integrated with the head associated with the inlet, the inlet poppet valve comprising a linearly actuatable valve stem; g) at least one outlet poppet valve controlling the gas stream outlet and integrated with the head associated with the outlet, the outlet poppet valve comprising a linearly actuatable valve stem; and h) at least one actuator engageable with the linearly actuatable valve stem of f) and/or g) providing valve opening and closing by imparting linear motion to the poppet valve to allow gases to pass from outside the adsorber to inside the adsorber body, and from inside the adsorber body to outside the adsorber so as to provide changeable flow operation. - View Dependent Claims (16)
