The present invention discloses a gas-solid separating method and a gas-solid separating system for simple substance sulphur in sulphur-containing exhaust. The gas-solid separating method for simple substance sulphur in sulphur-containing exhaust comprises the following steps: first, cooling sulphur-containing exhaust at an extremely high speed; then, separating dust; finally, recycling a heavy liquid phase solvent and simple substance sulphur; according to the method disclosed by the present invention, the separating efficiency of the simple substance sulphur is up to 90 percent or above; moreover, the exhaust is further purified, and an environment pollution accident is avoided; in a separating process of the simple substance sulphur, the heavy liquid phase solvent of the simple substance sulphur evaporates to form a gas phase solvent which can be recycled as the liquid phase solvent for reusing through cooling, so that the sulphur removing cost is reduced. The system comprises a quick cooling system, a low-temperature washing and purifying system, a light liquid phase and heavy liquid phase separating system, a washing liquid recycling system and a simple substance sulphur recycling system. The system disclosed by the present invention has the advantages of stability and high efficiency in sulphur-containing exhaust treatment, high simple substance sulphur separating efficiency, energy conservation and environmental protection.

Disclosed herein is a rotating packed bed, RPB, for mass transfer between a sorbent and a gas, the RPB comprising: a central chamber arranged to receive a flow of a sorbent that is a liquid; and a flow path for the sorbent between the central chamber and a region for mass transfer between a gas and the sorbent; wherein, in use, the flow of sorbent through the region for mass transfer is substantially in cross-flow with the flow of gas through the region for mass transfer. Advantageously, mass transfer between a liquid sorbent and a gas is improved.

An air-liquid amine contactor for gaseous carbon dioxide extraction includes a manifold and a contactor. The manifold dispenses liquid amine into the contactor in a controlled manner. The liquid amine dispenses as a film that spreads over a plurality of plenum bodies mounted within the manifold. Each of the plurality of plenum bodies includes a plurality of V-shaped channels which increase the overall surface area of the plenum body. The plurality of V-shaped channels includes a first inner wall and a second inner wall positioned at an angle ranging from 24 to 28 degrees to each other. Further, each of the plurality of wedge-inserts includes a first fluid orifice, a second fluid orifice, and an inlet orifice. Each wedge-insert is positioned within a corresponding V-shaped channel. Finally, the contactor is mounted adjacent to the contactor which positions the plurality of V-shaped channels perpendicular to a bottom surface of the manifold.

The method includes limiting saturation of output absorbent with dispersed and recirculating gas molecules with full completion of chemical reactions in the first stage, countercurrent contact between the gas and absorbent in the loading elements of the nozzle in the second stage, further extraction of gas molecules by absorbent in the irrigation chamber of the third stage. Then the gas for the absorption of hard-to-recover components is transferred to the irrigation chamber of the fourth stage, where it is irrigated with fine droplets of fresh and circulating absorbent. Then the direct-flow contact between the gas-liquid phase is carried out in the checker loading elements of the fifth stage. Finally, interphase contact of depleted gas with absorbent is completed in the bubbling chamber of the sixth stage and in the interchamber space between the fifth and sixth chambers. The bubbling chamber of the I stage is divided by a partition into the final and the main bubbling chambers, and the ceramic dispersants and/or hypersonic Hartmann's oscillators are installed in them. The pipeline of the removal of the saturated absorbent is attached to the final chamber, and the circulation pumps are attached to the main chamber of the I stage the and bubbling chamber of the VI stage, the pressure pipelines of the circulation pumps are connected to the scattering reflectors of the irrigation chambers of the III and IV stages. The pressure pump pipeline for supplying the fresh absorbent is connected to the hypersonic acoustical dispersant and the scattering reflectors which are set in the irrigation chamber of the IV stage. The space between the chambers of the I and the II stage is closed and attached by the pipeline of the gas discharge conduit to the distribution nozzles mounted at the bottom of the checker chamber of the II stage. The pipeline for the gas outlet conduit of irrigation chamber of the III stage is attached to the irrigation chamber of the IV stage. The pipes of supply, bypass and gas withdrawal and absorbent are equipped with the magnetic valves. Pumps are equipped with frequency converters (inverters). Valves, inverters and air conditioner are connected to the unit of the automatic control system. The invention allows to achieve the effect of a finite solubility of hard-to-recover gas components in the liquid and the automation of technological processes in order to reduce the power consumption.

A gas-liquid contacting apparatus and method are described, in which at least one rotor assembly including packing is arranged in a contacting chamber containing at least one stator assembly including at least one heat exchanger arranged to thermally modulate the gas-liquid contacting so that each stator assembly is operatively arranged with each stator assembly to provide gas-liquid contacting at temperatures effective for mass exchange between the gas and liquid. The rotor and stator assemblies may be of annular shape, or may be of disk shape in a stacked array of rotor assemblies alternating with stator assemblies. Such apparatus and method are usefully employed for CO.sub.2 capture from CO.sub.2-containing flue gases such as combustion effluents from power generation plants.

The present invention relates to a distributor tray (2) for a column intended for heat and/or material exchange between a gas and a liquid. The tray comprises gas passage means (4), liquid passage means (6) and distribution means (5) for distributing the liquid with a preferred orientation. The invention also relates to a heat and/or material exchange column, and to the use of the column.

A scrubber for cleaning a gas comprises a casing extending along a longitudinal central axis and enclosing a scrubbing chamber. The casing has a gas inlet and a gas outlet. The casing is configured to permit flow of the gas through the scrubbing chamber in a flow direction from the gas inlet to the gas outlet. A deflector device in the scrubbing chamber between the gas inlet and outlet forms a gas passage between the deflector device and the casing. The deflector device comprises an upstream surface facing the gas inlet. A spraying nozzle is configured to spray a scrubbing liquid into the scrubbing chamber and the gas flow. A separation device comprises a shield element and is arranged between the upstream surface of the deflector device and the gas inlet. The shield element shields the upstream surface from the gas flow and is perforated by a plurality of holes.
