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 evoporative 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.

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.

A cyclonic chiller-separator, including a vertically oriented treatment tower defining an interior space and having an exhaust inlet disposed in an upper portion, and a chimney with an exhaust outlet; an exhaust stream conduit in fluid communication with said interior volume of said treatment tower through said exhaust inlet, wherein said exhaust inlet is configured to induce cyclonic fluid motion in an exhaust stream entering said interior volume; a coolant water source; and a plurality of nozzles disposed about interior walls of said treatment tower and in fluid communication with said coolant water source for spraying cooling water into said interior volume above and into an exhaust stream introduced into said interior volume so as to cool, condense, and precipitate volatile organic compounds and organic acids, and to entrain and remove particulates from the exhaust stream.

The device (1) for bringing a gas and a liquid into contact includes an enclosure (E), first means (5) for introducing into the enclosure and circulating therein a gas stream (G), second means (6) for introducing into the enclosure and circulating therein a liquid stream (L) that circulates inside the enclosure (E) in the same direction as the gas stream (G), and means (4A) for mixing the gas stream (G) and the liquid stream (L). These mixing means (4A) are positioned inside the enclosure (E) in the path of the gas stream and liquid stream and are capable of locally deflecting upward, and/or of locally causing to rise, at least one portion of the gas stream and liquid stream, so as to locally create turbulences in the gas stream and in the liquid stream.

A system for separation of gas and solid at least comprises a cyclone trapping device and a negative pressure waste gas treatment device. The cyclone trapping device has a gas inlet and outlet chamber and a cyclone separation chamber communicating with each other, and the gas inlet and outlet chamber has a gas inlet tube communicating with a process waste gas source and a gas outlet tube communicating with the negative pressure waste gas treatment device. A process waste gas generated by the process waste gas source is introduced into the gas inlet and outlet chamber through the gas inlet tube to generate cyclones, thereby separating a portion of solid particles from the process waste gas, and transmitting the process waste gas to the negative pressure waste gas treatment device through the gas outlet tube in order to further separate the remaining solid particles from the process waste gas.
