Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve performing dampening for fluctuations in the streams conducted away from the adsorbent bed unit. The process may be utilized for swing adsorption processes, such as rapid cycle TSA and/or rapid cycle PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.

Apparatus and system for swing adsorption processes

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.

Adsorption processes and systems utilizing step lift control of hydraulically actuated poppet valves

Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing an input feed stream through two swing adsorption systems as a purge stream to remove contaminants, such as water, from the respective adsorbent bed units. The wet purge product stream is passed to a solvent based gas treating system, which forms a wet hydrocarbon rich stream and a wet acid gas stream. Then, the wet hydrocarbon rich stream and the wet acid gas stream are passed through one of the respective swing adsorption systems to remove some of the moisture from the respective wet streams.

Apparatus and system for swing adsorption processes related thereto

Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve performing a startup mode process prior to beginning a normal operation mode process to remove contaminants from a gaseous feed stream. The startup mode process may be utilized for swing adsorption processes, such as TSA and/or PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.

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 pipeline quality natural gas to form a stream that complies with liquefied natural gas (LNG) specifications. The process may involve a combined TSA and PSA process, which is utilized to remove contaminants from the feed stream.

Apparatus and system for combined temperature and pressure swing adsorption processes related thereto

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 is purged with a purge stream that is provided from the overhead of the demethanizer. The configuration integrates a RCTSA dehydration system with a cryogenic recovery system.
