摘要： Hydrogen sulfide is removed from gas streams by reaction with sulfur dioxide to produce sulfur. The reaction is effected in a reaction medium comprising a non-aqueous Lewis base with a pKb value of about 6 to about 11. The reaction medium possesses a specific combination of properties: a) absorbs sulfur dioxide and reacts chemically therewith to form a reaction product; b) absorbs hydrogen sulfide; c) removes the hydrogen sulfide from the gas stream through contact of the gas stream with the reaction medium in the presence of free sulfur dioxide, and/or the reaction product; d) acts as a catalyst for the overall reaction of the hydrogen sulfide with sulfur dioxide to produce sulfur; and (e) has the capacity to absorb sulfur dioxide in sufficient quantity to remove substantially all the hydrogen sulfide from the gas stream, notwithstanding short term variations in the stoichiometric balance between the hydrogen sulfide and the sulfur dioxide in the reaction medium.

摘要： Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. The same principal may be employed in other procedures in which a gaseous phase is dispersed in a liquid phase to effect an interaction between components present in such phases. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell is also described. In order to effect mass transfer and rapid reaction gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index of gas through the openings in the shroud is at least about 18 per second per opening. Each of the openings has an area corresponding to an equivalent diameter of less than about one inch.

Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. The same principle may be employed with other procedures in which a gaseous phase is dispersed in a liquid phase to effect an interaction between components present in such phases. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell also is described.

To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index of gas through the openings in the shroud is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch.
摘要翻译： 组分通常但不排他气体组分在液体介质中从气流中除去并化学转化为不溶相或物理去除。 具体地，硫化氢可以通过在改性的搅拌浮选槽中的水性螯合过渡金属溶液中的氧化从气流中除去。 相同的原理可以用于其中气相分散在液相中以实现在这些相中存在的组分之间的相互作用的其它方法。 还描述了包括这种改进的搅拌浮选槽的气液接触装置，通常是组合的化学反应器和固体产物分离装置。 为了实现有效的传质和快速反应，通过以至少约350in / sec的叶片尖速度旋转叶轮来形成含有硫化氢和氧气的气泡。 达到要求的剪切。 为了帮助反应，周围的护罩具有多个开口，通常具有相当直径的纵横比约为1的开口，并以均匀的图案排列，例如提供通过其中的小于约0.02磅/分钟/开口的气流 护罩。 通常，通过护罩中的开口的气体的气体速度指数为每个开口每秒至少约18次，优选每个开口每秒至少约24次。 每个开口具有对应于小于约一英寸的当量直径的面积。
