System for integrating valves and flow manifold into housing of pressure exchanger

A system, comprising:

• an isobaric pressure exchanger (IPX) configured to couple to a manifold and to exchange pressure within the IPX between a first liquid at a first pressure and a second liquid at a second pressure, wherein the IPX comprises:
• a housing comprising an annular portion, a first end structure, and a second end structure, wherein the first and second end structures are coupled to opposite ends of the annular portion;
• and
• at least one high pressure shut-off valve disposed within the first end structure or the second end structure, wherein the at least one high pressure shut-off valve extends crosswise relative to a longitudinal axis of the IPX within the first end structure or the second end structure, and wherein the at least one high pressure shut-off valve extends across both a low pressure liquid passage and a high pressure liquid passage within the first end structure or the second end structure.

• a first manifold connector disposed within the first end structure;
• a second manifold connector disposed within the second end structure, wherein the first and second manifold connectors are configured to couple the IPX to the manifold;
• a first high pressure shut-off valve disposed within the first end structure;
• and
• a second high pressure shut-off valve disposed within the second end structure, wherein the first and second high pressure shut-off valves are configured to control a flow of high pressure liquid into and out of the IPX via the first and second manifold connectors, and wherein the first high pressure shut-off valve extends crosswise relative to a longitudinal axis of the IPX within the first end structure, the second high pressure shut-off valve extends crosswise relative to the longitudinal axis of the IPX within the second end structure, the first high pressure shut-off valve extends across both a first low pressure liquid passage and a first high pressure liquid passage within the first end structure, and the second high pressure shut-off valve extends across both a second low pressure liquid passage and a second high pressure liquid passage within the second end structure;
• wherein the first manifold connector or the second manifold connector comprises a first end, a second end, a central portion between the first end and the second end, and wherein the first end comprises a first threaded portion, the second end comprises a second threaded portion, the first and second threaded portions are disposed outside of the housing, and the central portion is disposed within the housing.
