摘要： A dry particulate sulfite-containing material produced in a flue gas desulfurization process is oxidized and agglomerated in a fluidized bed reactor, wherein the material is fluidized in an oxygen-containing gas. The oxygen-containing gas which is supplied to the fluidized bed has a temperature below the agglomeration temperature of said particulate material. Due to the exothermic character of the oxidation, the temperature of the fluidized bed is maintained above the agglomeration temperature of the particulate material. Gas with entrained particles leaving the fluidzed bed are cooled during its passing through the freeboard of the fluidized bed reactor, whereby problems due to sticking of said entrained particles are avoided. At least a part of said entrained particles are recycled to the fluidized bed reactor.A fluidized bed reactor is provided suitable for performing the combined oxidation and agglomeration.
摘要翻译： 在烟道气脱硫工艺中生产的含干燥的含亚硫酸成份的材料在流化床反应器中被氧化和附聚，其中材料在含氧气体中流化。 供给流化床的含氧气体的温度低于所述颗粒材料的附聚温度。 由于氧化的放热特性，流化床的温度保持高于颗粒材料的附聚温度。 带有流出床的夹带颗粒的气体在通过流化床反应器的干舷时被冷却，从而避免了由于粘附所夹带的颗粒引起的问题。 至少一部分所述夹带的颗粒被再循环到流化床反应器中。 提供了适于进行组合氧化和附聚的流化床反应器。

摘要： Spent absorbents resulting from desulfurization of flue gas in a spray drying-absorption process contain substantial amounts of sulfite, e.g. calcium sulfite. Said sulfite is oxidized into sulfate by heating of the spent absorbent in the presence of an oxygen-containing gas, preferably at temperatures of 350.degree.-600.degree. C. Thereby the spent absorbents may be converted into materials having industrial utility.

摘要： A process for simultaneous removal of sulfur oxides (SO.sub.x) and nitrogen oxides (NO.sub.x) from gaseous mixtures (such as flue gases and industrial waste gases) containing them which comprises contacting the gaseous mixture with a particulate alkaline earth hydroxide and reaction products of the gaseous mixture and the hydroxide maintained in a moving bed reactor (preferably a fluid bed reactor) at a temperature of about 85.degree. C. to about 150.degree. C. in the presence of water vapor and oxygen and in the substantial absence of liquid water. A baghouse or other particle removal means preferably is employed to extract solid material such as fly ash and reaction products from the gaseous mixture being treated and to further capture unreacted SO.sub.x /NO.sub.x.

摘要： There are disclosed sterilant compositions having improved biocompatibility comprising a sterilant such as sodium chlorite, an acid such as citric acid, and a buffer such as sodium bicarbonate, the compositions forming an isotonic solution with pH of approximately 7.3.The compositions are particularly useful for cleansing and sterilizing kidney hemodialysis apparatus with minimal disruption of the protein layer which forms on the internal surface of the hollow fibers of a dialysis membrane when a patient is undergoing treatment with the apparatus thus establishing improved biocompatibility between patient and apparatus. The compositions are also useful in other areas of technology, such as, for example, food and wine making technologies.
