Abstract
Official abstract text for this publication.
A frac system that includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system, comprising: a frac system, comprising: a high-pressure pump configured to pump a first fluid that is substantially proppant free; a low-pressure pump configured to pump a second fluid containing a proppant; a hydraulic energy transfer system configured to block the flow of the second fluid through the high-pressure pump while exchanging pressure between the first fluid and the second fluid, wherein the hydraulic energy transfer system comprises a rotary isobaric pressure exchanger; and a bypass valve when in an open position is configured to redirect the second fluid through the high-pressure pump and when in a closed position is configured to block the second fluid from flowing through the high-pressure pump. 2. The system of claim 1 , wherein the frac system comprises a controller that controls the flow of the first fluid and the second fluid into the hydraulic energy transfer system.
