Apparatus (1) for treating a mixture (M) of gases, containing a first gaseous component (G1) and at least one second gaseous component (G2), so as to separate said first gaseous component (G1) from said second gaseous component (G2), said apparatus (1) being configured to implement a process configuration comprising at least one separation stage (10, 20, 30) of the membrane type, said apparatus is characterised by comprising: a first module (60) comprising at least a first frame (61) on which a first piping system (62) is mounted, at least two second modules (70, 70', 70"), and wherein each second module (70, 70', 70") comprises: ■ at least one second frame (71), ■ at least one membrane separation unit (50) of said at least one separation stage (10, 20, 30) which is mounted on said second frame (71), and wherein said first piping system (62) of the first module (60) is connected, or is intended to be connected, with said at least one separation unit (50) of at least two second modules (70, 70', 70").

A vacuum evaporation-concentration installation (1) for treating liquid mixtures is provided with a vacuum evaporation unit (100) comprising: a boiling chamber (110) in which a mixture to be treated is taken to boiling condition under a vacuum; heat exchange means (120) intended to heat the mixture to cause said boiling; and a vapor compression line (130) hydraulically connecting a vapor discharge opening (OP1) of the boiling chamber (110) to the heat exchange means (120) and comprising compression means (131) for compressing an evaporated fraction of the mixture discharged from the boiling chamber (110). The heat exchange means (120) comprise a pillow-plate heat exchanger (121, 122) arranged inside the boiling chamber (110) in a region at least partially floodable with said mixture. A vacuum evaporation-concentration process that can be carried out in such installation is also described.

A process of valorisation of agro-food wastes and/or by-products is provided, wherein a solid raw material to be processed is submitted to a sequence of solid-liquid extraction steps arranged to produce solid extracts of nutraceutical substances. Such a sequence comprises three steps in a first of which extraction is carried out with cold water, in a second with a hydroalcoholic solution and in a third with hot water, and the extracted liquids are processed for obtaining: - a dry solid extract containing dietary fibres and water-soluble polyphenols; - a dry solid extract rich in water-insoluble polyphenols; and - a dry solid extract rich in vegan proteins, wherein the processing of the liquid extracts obtained in the first and second steps includes a filtration and concentration step, and the processing of the liquid extract obtained in the third step includes a precipitation step followed by a centrifugation step, and wherein the filtration step and the concentration step and the centrifugation step, respectively, are followed by a drying step.

There are described a mechanical vapor recompression vacuum evaporation-concentration process and installation in which evaporation takes place at temperatures lower than 65°C and compression of the generated vapor is carried out by means of a high-performance turbofan.

A plant and process for capturing carbon dioxide directly from a gaseous mixture is provided, wherein the movement of air in the plant and the desorbing step to capture carbon dioxide are supported by renewable sources, preferably solar thermal energy.

To provide a manual winding device for a filter after using a cloth air filter in a ventilation opening part which is practical and versatile.SOLUTION: A manual winding device for a filter after use of a fabric air filter on a ventilation opening present on a casing of a machine or electrical apparatus requiring filtration of suction air, comprising: A winding reel whose ends are supported by a guide pin 21 and a drive pin 22 for the filter during winding; the pins are supported on special sides joined to the coupling base; the side pressers 7 slide in the grooves between a rest position 19 and a working position; the coupling base 8 has a support on the back side for housing a permanent magnet; guide ears for said fabric filter during winding are applied to the coupling base; each pin has a bayonet-shaped serration 23 suitable for being optionally inserted in a pin seat at a specific pin seat 24 allowing the insertion of a support and guide or drive pin.SELECTED DRAWING: Figure 1

A system (1) for the capture of carbon dioxide from an aeriform mixture comprising a frame (2), a first filter (3) and a second filter (4) operatively connected to the frame (2) and comprising an adsorbent configured to adsorb carbon dioxide. The first filter (3) and the second filter (4) are aligned with one another along a direction (X). The system (1) further comprises a desorber module (5) configured to desorb the carbon dioxide previously selectively adsorbed by the first filter (3) or the second filter (4) and a mechanism (6) adapted to move the desorber module (5) relative to the frame (2) between the first filter (3) and the second filter (4) along the direction (X). The system (1) also comprises an electronic control unit (90) operatively connected to the mechanism (6) and is configured to control the movement of the desorber module (5) between the first filter (3) and the second filter (4) as a function of one or more operating parameters ( tads t P, T).
