A novel approach for applying energy recovery devices (“ERD”s) to fluid systems which increases the fluid pressure by using ‘waste’ stream energy, and concurrently obviate the need an ancillary power source such as a motor or engine directly connected to the energy recovery device. This is achieved using a system or apparatus comprising two or more energy recovery devices, and/or at least one (or two or more) energy recovery device having two or more energy recovery device stages, wherein the system or apparatus has a pumping (or compressing) circuit of the energy recovery devices are arranged in parallel, while the turbine (or motor) circuit of the energy recovery devices are arranged in series. An advantage of such systems or apparatus provides that the one or more energy recovery devices now operate as an intensifier, increasing the pressure available to a given process, i.e., a separation process. A further advantage of such systems or apparatus is in the provision of a significant disparity in the flowrates of a process.

A positive-displacement pump or turbine includes a rotor casing that defines a rotor chamber having a contoured wall that forms a plurality of lobes. A rotor is positioned within the rotor chamber, and has an outer rotor surface spaced inward from the contoured wall at the lobes. Vanes are mounted around the outer rotor surface, and structures associated with the vanes follow a track or groove defined by the rotor chamber as the rotor spins, thereby forcing the vanes radially inwardly and outwardly to follow a curvature of the contoured wall.

A positive-displacement pump or turbine (10) includes a rotor casing (14) that defines a rotor chamber (32) having a contoured wall (34) that forms a plurality of lobes (20, 22, 24, 26). A rotor (30) is positioned within the rotor chamber (32), and has an outer rotor surface (30a) spaced inward from the contoured wall (34) at the lobes (20, 22, 24, 26). Vanes (28) are mounted around the outer rotor surface (30a), and structures associated with the vanes (28) follow a track or groove (40, 42) defined by the rotor chamber (32) as the rotor (30) spins, thereby forcing the vanes (28) radially inwardly and outwardly to follow a curvature of the contoured wall (34).

A positive-displacement unitary pump and turbine is operable as a fluid energy exchanger using a charging fluid as motive force and acting upon a separate feed fluid that exits the turbine at an elevated energy state. The rotor casing defines a rotor chamber having a contoured wall that forms a plurality of lobes, typically in an even number. Each lobe has an inlet port and an outlet port defined by the contoured wall, and the rotor has a plurality of vanes that follow the contoured wall as the rotor spins. The rotor is driven by the charging fluid entering first and second lobes, located generally opposite one another, and exiting the lobes at a lower energy state. The driven rotor is operable to elevate the energy level of a feed fluid in third and fourth lobes, located generally opposite one another.
