摘要： Process and apparatus are disclosed for capturing and converting an ozone-depleting alkyl halide fumigant from a fumigant/air mixed stream (14) by absorbing it into a metal hydroxide-alcohol buffer solution (26) in an absorber/scrubber (12) to produce a fumigant-free air stream. The captured alkyl halide in aqueous alcohol solution can actively react with the metal hydroxide in alcohol solution to produce a value-added product, such as a precipitate metal halide, and another alcohol that further enhances absorption. The absorbing solution is well-mixed with make-up alcohol and alkali streams to maintain the concentration of the metal hydroxide in the desired buffer solution range. The solid precipitate metal halide is separated from the liquid stream, and the metal hydroxide-containing mixed alcohol stream is recycled to the absorber/scrubber (12).

摘要： The present application provides a hydrophilic and hydrophobic composite packing-based rotating packed bed and a system. A hydrophobic packing and a hydrophilic packing are formed into a composite packing. When said packing cuts liquid, the hydrophobic packing can sufficiently disperse the liquid so as to make the dispersion of the liquid in the packing zone more uniform, and the wettability of the hydrophilic packing allows the liquid to spread sufficiently so as to increase the wetting efficiency of said packing. Different mixing effects can be achieved by means of reasonable combination. Due to the limited number of hydrophilic packing layers and hydrophobic packing layers in said composite packing, the phenomenon of droplet aggregation caused to liquid in a single hydrophobic packing zone and the phenomenon of reduction of liquid turbulence caused to liquid in a single hydrophilic packing zone can be avoided. The negative effects of hydrophilicity can be alleviated or offset by means of hydrophobicity, and the negative effects of hydrophobicity can be alleviated or offset by means of hydrophilicity. Therefore, applying a hydrophilic and hydrophobic composite packing to a rotating packed bed can further improve the mass transfer and mixing performance thereof.

摘要： 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.

摘要： A method for collecting particles or gaseous chemicals is provided. The method includes providing liquid to a tube of a droplet generator, heating, with a heater of the droplet generator, the tube to provide vapor to a gas flow channel inside the tube, passing a gas flow containing the particles or gaseous chemicals through the gas flow channel inside the tube to obtain droplets including the particles or gaseous chemicals, and passing the droplets including the particles or gaseous chemicals to a wall of a collecting device such that the droplets including the particles or gaseous chemicals hit the wall. The temperature inside the gas flow channel is higher than a temperature inside the collecting device.

摘要： An apparatus and methods to eliminate PFAS from wastewater biosolids through fluidized bed gasification. The gasifier decomposes the PFAS in the biosolids at temperatures of 900-1800° F. Synthesis gas (syngas) exits the gasifier which is coupled to a thermal oxidizer and is combusted at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat can be recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger that is coupled with the thermal oxidizer. Cooled flue gas is mixed with hydrated lime, enhancing PFAS decomposition, with the spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements. The apparatus and methods thereby eliminate PFAS from wastewater biosolids and control emissions in the resulting flue gas.

摘要： A method for the reduction and prevention of mercury emissions into the environment from combusted fossil fuels or other off-gases with the use of peracetic acid is disclosed. The peracetic acid is used for the capture of mercury from the resulting flue gases using a flue gas desulfurization system or scrubber. The method uses peracetic acid in conjunction with a scrubber to capture mercury and lower its emission and/or re-emission with stack gases. The method allows the use of coal as a cleaner and environmentally friendlier fuel source as well as capturing mercury from other processing systems.
