  • Patent number: 11655910
    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.

  • Patent number: 11110388
    Abstract: 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.
