In-line separator is a device for separating continuous gas-liquid flow into gas flow and liquid flow.
Gas-liquid mixture is twisted in the tangential swirler, which is installed at the device inlet, and further directed into the cylindrical channel where the liquid is separated at the pipe walls. Liquid film is formed on the walls of cylindrical channel and the gas stream is formed in the near-axial zone. At the outlet of cylindrical channel there is a separating section, where the flow is divided into gas stream and liquid stream. All elements of separator are mounted within the pipeline.
