Abstract
A moving wall multiphase compressor-pump-expander system utilizes the relative rotation of a ring, a central body, and a housing with respect to each other, where the ring is concentrically positioned in a channel between the central body and the housing. The ring has a series of vanes passing through it and pivotally attached on each side to the walls of the channel in the housing to compress a fluid. The channel has low friction walls on either side to reduce the friction between the vanes the walls. The system is able to compress and expand fluids and as such can function as a pump.
Claims10
A moving wall multiphase compressor-pump-expander system comprising:
- a housing;
- a central body positioned concentrically within the housing, wherein a channel is delineated between a first running surface of the housing and a second running surface of the central body, wherein the first running surface and the second running surface are each contoured according to a polygonal profile with a plurality of lobes;
- a first low friction wall being attached to the first running surface;
- a second low friction wall being attached to the second running surface;
- a ring positioned within the channel having a plurality of radial slots;
- a plurality of vanes slidingly attached within and passing through the plurality of radial slots, wherein the plurality of vanes is pivotally attached between the first low friction wall and the second low friction wall;
- wherein the first low friction wall, the second low friction wall, the ring and the vanes form spaces with variable geometry;
- wherein the housing and the central body are rotationally coupled;
- and
- wherein a fluid is injected into the spaces to have its pressure altered as the housing and central body and the ring experience rotation relative to each other.
