Abstract: Provided is a cyclonic fluid separator, method of fluid separation, and a method of installing a cyclonic fluid separator. The cyclonic fluid separator includes a throat portion arranged between a converging fluid inlet section and a diverging fluid outlet section including an inner primary outlet for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components. A central body extends along a central axis of the cyclonic fluid separator through at least part of the inlet section of the separator. The central body has, at a location upstream of the throat portion, a larger outer width than a smallest inner width of the throat portion; swirl imparting means arranged in the inlet section for creating a swirling motion of the fluid within at least part of the separator. The swirl imparting means are adjustable; and an adjusting mechanism configured for adjusting the swirl imparting means for varying the swirling motion of the fluid.
