Abstract: A device and method for scrubbing an absorbate from a gas is described. The rotational absorber device comprises a housing having a gas inlet, a gas outlet, an absorbent liquid inlet and an absorbent liquid outlet; a rotor mounted for rotation in said housing and connecting to the inlets and outlets, the rotor comprising a plurality of scrubbing channels extending axially and parallel to a common rotation axis; and means for rotating the rotor. The device and method provide a scrubbing of the gas with improved selectivity and efficiency.

Abstract: The invention relates to a device for separating a flowing medium mixture into at least two fractions, comprising rotating means, means for physically increasing the difference in mass density of the fractions for separating, a feed for medium and a first outlet for discharging one of the fractions of the separated medium mixture. The invention also relates to a method for separating a flowing medium mixture.

Abstract: The invention relates to a device for separating a flowing medium mixture into at least two fractions with differing mass density. The device comprises an inlet for the medium mixture to be separated, which connects to first separating means for separating the flowing mixture in at least a first and a second fraction, and that connect to first and second outlet means for discharging the first and second fractions. The device further comprises a feedback loop comprising second separating means between the second outlet means and the inlet means of the first separating means. The invention also relates to a method for separating a flowing medium mixture into at least two fractions with differing mass density, using the claimed device. The device and method allow to obtain a more selective separation, particularly in purifying natural gas.

Abstract: The invention relates to a separating body which can be set into rotation to separate solid or liquid particles of micron or submicron size from a fluid, wherein the body has a large number of separating ducts with singly connected walls over a substantial part of the axial length, where the walls of at least one of the separating ducts are not parallel to the axis of rotation. The tangent of the angle between the tangent planes of the walls of the separating duct and the axis of rotation is designated with tan .alpha., the radial width of the separating duct is designated with d, the length of the separating duct is designated with L and the rotation speed of the separating body is designated with .OMEGA. where these variables are chosen in mutual dependence in a manner such that the dimensionless number (.OMEGA.Ld tan .alpha.)/.nu. is located over a substantial part of the separating duct in the range up to 192, wherein .nu. is the kinematic viscosity of the fluid.
