Integrated power pump

A pump system, comprising a high pressure pump and an integrated power pump, wherein:

• the integrated power pump comprises a housing, a process stream input opening, a process stream output opening, a power stream inlet, and a rotor;
• the high pressure pump is fluidly coupled to the integrated power pump and positioned remotely from the integrated power pump;
• the high pressure pump generates a power stream;
• the power stream inlet extends from an outer surface to an inner surface of the housing;
• the power stream inlet receives the power stream generated by the high pressure pump;
• the process stream input opening is formed in the housing and is configured to receive a process stream;
• the process stream output opening is formed in the housing and is configured to output the process stream;
• the rotor comprises an impeller, a shroud, and a turbine;
• the impeller comprises one or more fluid motive elements positioned about a central axis of the rotor and extending outward to the shroud;
• the turbine comprises one or more runners formed on an outwardly facing surface of the shroud of the rotor;
• the shroud extends radially about the one or more fluid motive elements of the impeller;
• the rotor is rotatably supported within the housing such that the shroud and the inner surface of the housing form a fluid path for the power stream to flow through the turbine;
• and
• the one or more runners of the turbine cause the rotor to rotate when the power stream flows through the fluid path impinging the one or more runners of the turbine thereby transferring energy from the flow of the power stream received through the power stream inlet into rotational energy of the one or more fluid motive elements of the impeller to propel the process stream from the process stream input opening out the process stream output opening.

A process for treating a process stream with a power stream with an integrated power pump comprising a housing, a process stream input opening, a process stream output opening, a power stream inlet, and a rotor, the process comprising:

• receiving the power stream through the power stream inlet, the power stream inlet extends from an outer surface to an inner surface of the housing of the integrated power pump;
• causing the rotor rotatably supported within the housing to rotate when the power stream flows through a fluid path defined by at least the inner surface of the housing and an outwardly facing surface of a shroud and the power stream impinges one or more runners of a turbine of the rotor formed on the outwardly facing surface of the shroud of the rotor;
• propelling the process stream, with one or more fluid motive elements positioned about a central axis of the rotor and extending outward to the shroud, from the process stream input opening out the process stream output opening as an exit process stream when the rotor rotates in response to the power stream flowing through the turbine;
• and
• intermixing the power stream with the exit process stream such that the integrated power pump outputs the power stream and the exit process stream together through the process stream output opening.
