Abstract

A system includes an isobaric pressure exchanger (IPX) that includes a housing and a rotor disposed within the housing. The system also includes a rotor advancing tool configured to engage and to move the rotor while the rotor is within the housing. The housing includes an opening that enables the rotor advancing tool to extend through the opening to engage and move the rotor.

First claim

The invention claimed is:

1. A system, comprising:
an isobaric pressure exchanger (IPX) comprising:
a housing, wherein the housing comprises a body portion and first and second manifolds disposed at opposite ends of the body portion;
a rotor disposed within the housing; and
a sleeve disposed about the rotor between the body portion and the first and second manifolds; and

a rotor advancing tool configured to engage and to move the rotor while the rotor is within the housing;
wherein the housing comprises an opening that enables the rotor advancing tool to extend through the opening to engage and to move the rotor, wherein the opening is disposed on the body portion, and wherein the sleeve comprises a sleeve opening radially aligned relative to a longitudinal axis of the IPX with the opening of the housing, and the sleeve opening enables the rotor advancing tool to extend through the sleeve to engage and to move the rotor.

2. The system of claim 1 , wherein the rotor comprises one or more grooves or protrusions that extend longitudinally at least along a portion of an outer surface of the rotor radially aligned relative to the longitudinal axis with the opening, and the one or more grooves or protrusions are configured to enable engagement with a tip portion of the rotor advancing tool.

3. The system of claim 1 , comprising a removable cover disposed over the opening to block fluid from leaking from the IPX.

4. The system of claim 1 , wherein at least a portion of the rotor advancing tool is configured to remain disposed within the IPX when the IPX is in operation.

5. A method for moving a rotor of an isobaric pressure exchanger (IPX), comprising:
stopping operation of the IPX prior to engaging the rotor with a rotor advancing tool;
depressurizing the IPX subsequent to stopping operation of the IPX and prior to engaging the rotor advancing tool with the rotor;
engaging the rotor with the rotor advancing tool by extending the rotor advancing through an opening of a housing of the IPX while the IPX is still coupled to external piping that provides fluids to the IPX, wherein the rotor is disposed within the housing; and
moving the rotor with the rotor advancing tool.

6. The method of claim 5 , comprising draining fluids from the IPX subsequent to stopping operation of the IPX and prior to engaging the rotor advancing tool with the rotor.

7. The method of claim 5 , removing a cover disposed over the opening prior to extending the rotor advancing tool through the opening.
