Fluid transfer seal assemblies, fluid transfer systems, and methods for transferring process fluid between stationary and rotating components using the same
Abstract:
Fluid transfer seal assemblies for transferring process fluid between a stationary component and a rotating component, fluid transfer systems, and methods for transferring process fluid between the stationary and rotating components via a fluid transfer assembly are provided. A rotatable component includes a sealing surface. The fluid transfer seal assembly comprises a face seal ring having at least one segment of a fluid passageway and a sealing face configured to be disposed opposite of the sealing surface. The sealing face or the opposed sealing surface includes a geometric feature for forming a hydrodynamic seal therebetween. A secondary seal is configured to be disposed between and contacting the face seal ring and the stationary component.
