US Patent 9283497 Abrasion resistant gas separator

A gas separator is configured to separate gas from a two-phase fluid. The gas separator includes a rotatable shaft and one or more separation stages. At least one of the one or more separation stages includes a rotor connected to the rotatable shaft and a channeled compression tube, wherein the channeled compression tube includes a compression tube hub and a plurality of channels. The channels are configured to isolate abrasive solid particles from the rotary components within the gas separator. The gas separator may optionally include a streamer upstream from the separation stage that reduces rotational currents upstream from the rotor.
