Abstract
A frac system that includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid.
Claims17
A pumping system, comprising:
- a rotary isobaric pressure exchanger (IPX) that during operation exchanges pressures between a first fluid and a second fluid, wherein the first fluid is a substantially particulate free fluid and the second fluid is a particulate laden fluid;
- and
- a controller that controls the flow of the first fluid and the second fluid into the rotary IPX, wherein the controller alters a flow of the first fluid and the second fluid in the pumping system to enable continuous fracing operation when the rotary IPX is no longer rotating.
A frac system, comprising:
- a rotary isobaric pressure exchanger (IPX) to exchange pressures between a first fluid and a second fluid, wherein the first fluid is a substantially proppant free fluid and the second fluid is a proppant laden fluid;
- a first flow meter configured to measure a first flow rate of the first fluid into a high pressure inlet of the rotary IPX;
- a second flow meter configured to measure a second flow rate of the second fluid into low pressure inlet of the rotary IPX;
- and
- a controller coupled to the first and second flow meters that controls the first flow rate of the first fluid or the second flow rate of the second fluid into the rotary IPX using feedback from the first and second flow meters and alters a flow of the first fluid and the second fluid in the frac system to enable continuous fracing operation when the rotary IPX is no longer rotating.

A pumping system, comprising:
- a rotary isobaric pressure exchanger (IPX) configured to exchange pressures between a first fluid and a second fluid, wherein the first fluid is a substantially particulate free fluid and the second fluid is a particulate laden fluid;
- a high-pressure pump configured to pump the first fluid, wherein the high-pressure pump is configured to provide the first fluid to a high pressure inlet of the rotary IPX;
- a low-pressure pump configured to pump the second fluid, wherein the low-pressure pump is configured to provide the second fluid to a low pressure inlet of the rotary IPX;
- and
- a flow path coupled to a low pressure outlet of the rotary IPX and a separator system disposed along the flow path, wherein the separator system is configured to remove particulate from the first fluid discharged from the low pressure outlet of the rotary IPX, and the flow path is configured to provide the first fluid after passing through the separator system to the high pressure pump.

- and
- a flow path coupled to a low pressure outlet of the rotary IPX and a mixing system disposed along the flow path, wherein the mixing system is configured to add particulate to the first fluid discharged from the low pressure outlet of the rotary IPX to convert the first fluid to the second fluid, and the flow path is configured to provide second fluid from the mixing system to the low pressure pump.
