Abstract: Method and apparatus for cleaning an air flow from particles, such as bacteria and other microorganisms. According to the invention, an aerosol of liquid droplets is generated in the air flow, whereafter the liquid droplets and the air flow are mixed and the droplets and particles are centrifugally separated from the air flow.

Abstract: A method of centrifugal separation of particles, comprising providing a gas flow containing the particles, charging the particles in the gas flow, generating an aerosol of polar liquid droplets introducing the aerosol into the gas flow for attracting the charged particles by the polar liquid droplets, and separating the liquid droplets comprising the attracted particles from the gas flow by the centrifugal separation.

Abstract: 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 evaporative 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.

Abstract: A method of separating particles (P) having different sedimentation velocities in a fluid sample (30) through centrifugal sedimentation comprises enclosing the sample (30) and rotating the sample about a primary axis (12) outside the sample at a first rotational speed (?), and about a secondary axis (22) located in the center of the sample at a second rotational speed (?), for subjecting the sample to a varying centrifugal field until each particle (P) has settled at a position which depends on the sedimentation velocity of the particle.
