A capture system for offshore carbon dioxide capture and a method for offshore carbon dioxide capture are described. A capture system for offshore carbon dioxide capture, the system comprising: a pressurised flue gas source configured to provide a pressurised flue gas 101; a solvent source configured to provide a liquid solvent; and a two-phase atomising nozzle in fluid communication with the pressurised flue gas source and the solvent source; wherein the two-phase atomising nozzle is configured for two-phase flow of a mixture of the pressurised flue gas and the liquid solvent in order to generate an atomised solvent spray of the liquid solvent.

A process gas suction structure for preventing a generation of products from a process gas due to a temperature drop is disclosed. The process gas suction structure includes a double tube structure, and a heating device configured to heat the double tube structure. The double tube structure includes a process-gas flow passage portion where the process gas flows, and a partition portion arranged outside of the process-gas flow passage portion.

A sprayer for settling dust of a coal mine includes: an outer housing, having at least one opening configured to spray water mist; a sprayer, placed in the outer housing, configured to spray water mist through the opening; a plurality of water curtain nozzles, configured to spray water curtain lines outside the opening to block suspended dust; and a support, configured to support the outer housing. The water curtain nozzles are in an equidistant arrangement around a center of the opening. A plurality of the water curtain nozzles are constructed such that the nozzles are all oriented toward the same point, to form a circular or conical water curtain.

The present invention can separate waste gases according to whether they are corrosive or non-corrosive to perform pyrolysis treatment thereof individually, wherein powder fixed to a heating module and a chamber is removed to increase operation efficiency and equipment durability, and the collected powder can be externally discharged even during operation.

An apparatus and a method for washing hydrocarbon product vapor are disclosed. The apparatus comprises housing, a first wash zone at a predefined cross-section of the housing for receiving the hydrocarbon product vapor, a plurality of injection units located within the first wash zone at predetermined intervals of the length of the housing for receiving wash oil. The injection units inject oil droplets formed from the received wash oil to contact the vapor and obtain a primary washed hydrocarbon vapor within the first wash zone. Further, a second wash zone is located above and in fluid communication with the first wash zone for receiving the primary washed hydrocarbon vapor. One or more spray headers receive wash oil and spray oil droplets formed from the received wash oil to contact with the primary washed hydrocarbon vapor, thereby forming a secondary washed hydrocarbon vapor.

A scrubber for cleaning exhaust fumes generated by internal combustion engines, in particular for reducing the concentration of the sulfur oxides SO.sub.x in exhaust fumes generated by the combustion of high sulfur content fuels, said scrubber comprising a main hollow tubular body, an inlet and an outlet for introducing and discharging said fumes into and from said main hollow tubular body, respectively, and inlet means for introducing at least partially atomized pressurized water into said main hollow body, wherein said inlet means comprise a plurality of nozzles arranged in said main hollow body and each adapted to dispense said at least partially atomized pressurized water.

A scrubber tray for a wet scrubber tower of a flue gas purification device includes a multiplicity of spindles, arranged across an inner horizontal cross section of the wet scrubber tower. Adjacent spindles are arranged at a horizontal distance to each other. At least some of the spindles are pivot-mounted to allow a rotative movement around a corresponding spindle axis and to arrange the respective spindle at a predetermined rotation angle. At least some of the spindles are equipped each with at least one protrusion, which extends outwardly from the respective spindle. The spindles and protrusions are shaped and arranged to provide flow-through openings between adjacent spindles and protrusions respectively. Each flow-through opening defines a corresponding flow-through area, and they add up to 10%-80% of the inner horizontal cross section of the associated scrubber tower, independently of the respective rotation angles of the spindles.
