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.

A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.

A method and installation for removing a gas from a flow of a gas mixture. A first liquid (82) is introduced in the flow (106) for evoporative cooling and saturation of the gas mixture. Small droplets of a second liquid (84) are provided which are capable of adsorbing and dissolving said gas and of a size small enough not to be sedimented by gravitation and big enough to be centrifugally separated. The small droplets are sprayed into the flow for adsorbing and dissolving said gas into the droplets, and the small droplets are centrifugally separated from the flow.
