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.
