1. A rotary pressure exchanger for transferring pressure from a first fluid to a second fluid, comprising;
a housing; and
a rotor mounted within the housing, and configured to rotate about an axis of rotation defining an axial direction, the rotor extending from a first rotor end in the axial direction to a second rotor end, a plurality of channels disposed inside the rotor and being configured to transfer pressure from the first fluid to the second fluid, and each channel of the plurality of channels extends parallel to the axis of rotation, the plurality of channels comprising a set of first channels and a set of second channels, and the rotor comprises a divider arranged between the first rotor end and the second rotor end to separate the first channels from the second channels, each first channel of the set of first channels extending from the first rotor end in the axial direction to the divider, and each second channel of the set of second channels extending from the second rotor end in the axial direction to the divider, and
the housing comprising two first fluid inlet ports to supply the first fluid to the first set of channels and to the second set of channels, two first fluid outlet ports to discharge the first fluid from the first set of channels and from the second set of channels, two second fluid inlet ports to supply the second fluid to the first set of channels and to the second set of channels, two second fluid outlet ports for discharging the second fluid from the first set of channels and from the second set of channels, the first fluid inlet ports and the first fluid outlet ports arranged at the first and the second rotor ends, and the second fluid inlet ports and the second fluid outlet ports arranged adjacent the divider with respect to the axial direction.
