摘要： A method for partially oxidizing, in a Claus furnace, at least one gas containing hydrogen sulfide and ammonia with at least one gas rich in oxygen. The residual ammonia content at the outlet of the furnace is measured with a laser diode. Based upon this measurement, the flow rates of the ammonia containing gases and the oxygen rich gases may be modified to obtain the desired residual ammonia content.

摘要： A process for the recovery of sulfur and carbon monoxide from metal sulfates in which the carbon monoxide is recycled as a reducing agent for reaction with the metal sulfate. Metal sulfates such as gypsum (calcium sulfate dihydrate) are processed to form sulfur dioxide. The sulfur dioxide is contacted with carbonaceous matter at sufficiently high temperature to form elemental sulfur and carbon monoxide. The carbon monoxide is then recycled for use as a reducing agent in the initial processing of the metal sulfate.

摘要： A process for the processing of spent photographic baths of black and white processes, namely developing baths with a preponderant content of alkali sulphite, particularly sodium sulphite, and fixing baths with a preponderant content of thiosulphates, particularly ammonium thiosulphate and/or sodium thiosulphate is proposed and is characterized in that following the deposition of the silver contained in the baths, the spent fixing baths are brought to a pH of approximately 0.5 with concentrated HCl and the elementary sulphur resulting from the decomposition of the thiosulphates is separated, whilst the remaining sulphurous acid intermediate solution is mixed with the spent developing baths and adjusted to a pH of approximately 2 and the resulting, SO.sub.2 -supersaturated solution is heated and pure SO.sub.2 is drawn off in a vacuum. Finally, the residual solution is adjusted to a pH of approximately 10 with Ca(OH).sub.2 and the liberated ammonia is drawn off.

摘要： A method and apparatus for desulfurizing a gas and regenerating a sorbent is disclosed. The sulfur-containing feed gas which can be an effluent gas from a coal gasification reactor, for example, is desulfurized with a particulated metallic oxide sorbent in a transport riser. The sulfided sorbent is than separated from a desulfurized effluent gas and regenerated by contact with an oxygen-containing gas in a transport riser. The regenerated sorbent is separated from an SO.sub.2 containing offgas and recycled to the desulfurization step. The degree of sorbent conversion in the desulfurization step is held at a low level and the sorbent regeneration rate is increased to avoid excessive temperature rise in the regeneration step. In such manner, sorbent cooling can be substantially eliminated. The regeneration riser preferably comprises a once-through lift riser to minimize the riser transport gas requirements to just oxidant gas or oxidant gas mixed with a reduced amount of diluent gas. A reduction in use of diluent gas give a relatively high offgas SO.sub.2 concentration of as much as 15 mole percent, suitable for sulfuric acid manufacture and/or reduction to sulfur.

摘要： A rotating tube heat treatment installation, for example a rotating tubular kiln for the thermal splitting of MgSO.sub.3, or a slag cooler for the separation of salts and aluminum, comprises as the main replaceable component, a rotating tube (1) which is surrounded by a tubular jacket (2) and separated therefrom by a gap. The tubular jacket (2) is linked to the rotating tube (1) by means of a carrier system, and has drive (8) and possible bearing races and bandings (9) mounted externally. The connections (3, 4) for the heat exchange fluid are disposed at its ends, and thermal insulation, in particular light insulation (7), is fitted internally. In this way the rotating tube, which is exposed to corrosion and thermal stresses, is simplified structurally and can be readily replaced.

摘要： Capture-fixation of SO.sub.2 from flue and non-ferrous smelter gases is achieved with the use of MgO aqueous slurry as an absorbing medium. During the absorption, most of the MgO is converted to MgSO.sub.4 and the rest is solubilized as MgSO.sub.3 and Mg(HSO.sub.3).sub.2. The clear solution obtained at the end of the absorption is brought to about 40.degree. C. and is treated with sulphuric acid in an amount representing at least 5% in excess of the stoichiometric requirement whereby sulphite and bisulphite of magnesium are converted to magnesium sulphate. The magnesium sulphate obtained above can be used in a two stage addition of potassium chloride to obtain magnesium chloride, and calcined dolomite added to the remainder whereby magnesium hydroxide is precipitated and may be filtered off from the resulting CaCl.sub.2 solution. The process provides a means of removing SO.sub.2 from flue and smelter gases and at the same time produces industrially important chemical products (SO.sub.2, H.sub.2 SO.sub.4, K.sub.2 SO.sub.4, MgO, CaCl.sub.2).
摘要翻译：通过使用MgO含水浆料作为吸收介质，可以实现烟道和有色金属冶炼气体SO2捕集固定。在吸收过程中，大部分的MgO被转化为MgSO 4，其余的以硫酸镁和Mg（HSO3）2的形式溶解。在吸收结束时获得的澄清溶液达到约40℃，并且用超过化学计量要求的至少5％的量的硫酸处理，从而将亚硫酸盐和亚硫酸氢盐转化成硫酸镁。得到的硫酸镁可以两步加入氯化钾，得到氯化镁，煅烧后的白云石加入其中，由此使氢氧化镁沉淀，并从所得的CaCl 2溶液中滤出。该方法提供了从烟道和冶炼气体中除去SO2的方法，同时产生工业上重要的化学产物（SO2，H2SO4，K2SO4，MgO，CaCl2）。
