Abstract: A valve installation is provided, including a valve assembly having a valve, and a fluidized valve actuator coupled with the valve assembly. The actuator includes at least two cylinders and pistons positioned to communicate fluid to apply pressure to the valve assembly. Extension of each piston communicates pressure to the valve assembly and at least partially lifts the valve into an at least partially lifted and open position. The valve installation may be used to regulate fluid flow in various systems, including cyclical swing adsorption processes.

Abstract: Systems and methods are provided for regenerating a bed containing absorbed and/or adsorbed CO2 using a low value steam stream. The steam stream can have a pressure of 10 kPa-a to 50 kPa-a and a temperature of 46° C. to 81° C. The steam stream can be used to displace CO2 from the bed, resulting in formation of a low pressure stream including water vapor and CO2. The stream containing water vapor and CO2 is then passed through a liquid ring pump that includes an associated ring cooler. The ring pump provides the suction necessary to draw the low value steam stream through the bed to displace the CO2. Due to the nature of operation of the liquid ring pump, the majority of water in the steam containing H2O and CO2 can be removed within the liquid ring pump, resulting in production of a stream comprising 90 vol % or more of CO2 at a pressure of 90 kPa-a or more.

Abstract: Methods, systems, and apparatus are provided for modulating fluid flow in a cyclical swing adsorption system that includes multiple adsorption bed vessels that are in fluid communication. When opening a valve to transition an adsorption bed vessel into a blowdown stage or a re-pressurization stage of a cyclical swing adsorption process, the valve is partially lifted from a closed position prior to being fully lifted. The valve includes a flow restriction aid positioned to restrict flow through the valve when the valve is in the partially lifted position.

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 remove contaminants, such as water, from the stream. As part of the process, the adsorbent bed unit may include additional space for the valves on the head 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.

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.

Abstract: A solids supply system having a solids deaeration zone and a solids pump zone, and a method for supplying the solids e.g., pulverized dry coal, to an application, e.g., gasification process. The solids deaeration zone includes a container having a passageway defined by one or more sloped walls. The solids deaeration zone is operable to deaerate and convey the solids to the solids pump zone. In the solids deaeration zone, the solids become sufficiently compacted prior to and upon entry into the solids pump zone to be effectively conveyed through the solids pump zone.
