Abstract: Disclosed is an inline separator for separating well fluid or gas-dominant fluid using centrifugal force. The inline separator includes: an outer pipe provided with an inlet; a vortex-generating rotor installed in the outer pipe; a fixed extraction pipe having an external diameter smaller than an internal diameter of the outer pipe and installed in the outer pipe at a downstream side of the vortex-generating rotor; a movable extraction pipe connected to an end of the fixed extraction pipe, close to the vortex-generating rotor, and having an extendable and retractable structure such that a position of an introduction hole of the movable extraction pipe is changeable; a pressure compensation pipe that applies pressure to oil or gas separated in a downstream end of the fixed extraction pipe; and a seawater discharge pipe connected to a portion of the outer pipe at which the fixed extraction pipe is disposed.
