1. A method of removing a gas from a flow of a gas mixture, characterized by:
introducing a first liquid in the flow for evaporative cooling and saturation of the gas mixture;
providing small droplets of a second liquid capable of dissolving said gas and of a size small enough not to be sedimented by gravitation and big enough to be centrifugally separated;
spraying the small droplets into the flow for adsorbing and dissolving said gas into the droplets; and
centrifugally separating the small droplets from the flow,
wherein the gas mixture is a combustion exhaust gas.
