Abstract: A device and method for capturing and disinfecting infectants including viruses such as SARS-CoV-2 and bacteria from a gas is described. The rotational disinfectant device includes means for transmitting the infectant-containing gas to a gas inlet of a housing, which housing has a gas outlet, a disinfectant liquid inlet and a disinfectant liquid outlet; a rotor mounted for rotation in said housing and connecting to the inlets and outlets, the rotor including a plurality of disinfecting channels extending axially and parallel to a common rotation axis; and means for rotating the rotor. A disinfectant liquid collector connects to the disinfectant liquid outlet and to a return conduit that connects with the disinfectant liquid inlet. A pump transfers disinfectant liquid from the disinfectant liquid collector to the disinfectant liquid inlet through the return conduit for re-use. The return conduit, the liquid collector outlet and the disinfectant liquid inlet form a closed fluid circuit.

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: A device for separating a flowing medium mixture into at least two fractions, comprising rotating means (7) in the form of a rotating assembly of feed channels (6) for rotating the flowing mixture for separating, a feed for the medium mixture (5) for separating connecting to the rotating means, and an outlet connecting to the rotating means for discharging one of the fractions of the separated medium mixture, wherein the medium mixture can display a substantially turbulent flow during separation. Also disclosed is a method for separating a flowing medium mixture.

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.
