    摘要： Sulfurous gas streams comprising hydrogen sulfide and carbon disulfide, such as produced as a by-product of the rayon-forming process, are processed to recover the components in a useable form. The gas stream first is contacted with an aqueous sodium hydroxide to dissolve out hydrogen sulfide and some of the carbon disulfide. The dissolved carbon disulfide is driven off from the solution and condensed as a liquid concentrate. Carbon disulfide remaining the gas stream is recovered, such as by condensation. The aqueous sodium sulfide solution which remains from removal of carbon disulfide is concentrated and the pH is adjusted, as necessary, to a value at which the sodium sulfide is predominantly in the form of sodium bisulfide. The concentrated sodium bisulfide solution is capable of reuse in the rayon-forming process along with the liquid concentrate of carbon disulfide.

    钠形式的值。 浓缩的二硫化钠溶液能够与人造丝形成过程一起再次与二硫化碳的液体浓缩物一起使用。

    摘要： Gas streams containing non-condensible gases (NCG's) including reduced sulfur compounds, such as hydrogen sulfide, dimethyl sulfide, dimethyl disulfide and mercaptans, are treated to remove the NCG's from the gas stream. Following an optional initial gas-liquid contact to cool the gas stream to its adiabatic dewpoint and to remove particulates, the gas stream is subjected to an intimate gas-liquid contact with aqueous chlorine dioxide, in one or more contact stages, to oxidize the reduced sulfur compounds and other oxidizable compounds present in the gas stream, and then the gas stream is passed through an entrainment separator to remove entrained liquid droplets. Acidic gases produced in the oxidization stage and residual chlorine dioxide generally are removed from the gas steam by intimate gas-liquid contact of the gas stream with an aqueous neutralizing and reducing solution, in one or more contact stages, and ten the gas stream is passed through an entrainment separator to remove entrained liquid droplets.

    摘要： Novel nozzle designs useful for forming atomized sprays of fine liquid droplets in a continuous gas phase or fine gas bubbles in a continuous liquid phase, for a variety of purposes, are described. In one embodiment, the nozzle comprises a multiple number of orifices communicating with a single source of both liquid and gas, usually air, to spray in different directions away from the nozzle. In another embodiment, both gas and liquid feeds to the nozzle are effected at the same end, opposite to a single spray orifice or a multiple number of spray orifices. Also described are a plurality of designs for replaceable orifices.
