An energy-dissipating device and fluid processing system is provided containing a compressor, a motor, a secondary fluid re-circulation loop, a purge line, and a fluid conduit. The compressor is configured to receive a hot fluid including condensable and non-condensable components, and produce therefrom a primary compressed fluid stream and a secondary fluid stream. The motor is configured to drive the compressor and for ingress and egress of the secondary fluid stream. The secondary fluid re-circulation loop is configured to control an operating temperature of the motor. The secondary fluid re-circulation loop includes a first energy-dissipating device configured to remove excess heat from the secondary fluid stream. The purge line separates a first portion of the secondary fluid stream in the fluid re-circulation loop from a second portion of the secondary fluid stream being returned to the motor. The fluid conduit receives the primary compressed fluid stream from the compressor.

Fluid processing system

Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. In some embodiments, the flowmeter includes a measurement section having a non-circular transverse cross-section in which one or more sensors for measuring flow are disposed. The non-circular measurement section can reduce distortion of ultrasonic waves, facilitate chordal measurements with flush-mounted transducers, and reduce the propagation distance between paired transducers. In some embodiments, the flowmeter includes a conditioning section with diametrically opposed longitudinal rib protrusions. The protrusions can reduce swirling flow, direct liquid components of a multi-phase flow towards the sidewalls of the flow path, and guide ballistic particles through the center of the flow path away from sensitive measurement devices.

Non-circular flowmeter

Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. A flowmeter can include an elongate body having a first end and a second end and a flow path extending between the first and second ends along a longitudinal axis. An ultrasonic transducer can be disposed in a measurement section of the flow path and configured to emit ultrasonic waves into a material flowing through the flow path. First and second protrusions can be formed in a conditioning section of the flow path upstream from the measurement section, the first and second protrusions extending radially inward from a sidewall of the flow path and being configured to reduce swirling flow through the measurement section.
