摘要： In an apparatus for continuously recovering sulfur from a gas stream containing 0.1 to 3.0 vol-% H2S, further gaseous sulfur compounds and sulfur, the gas stream first is passed over a reduction stage consisting of hydrogenation catalyst and then over a selective oxidation stage consisting of oxidation catalyst. To reduce the amount of apparatus involved, it is provided to arrange the reduction stage and the selective oxidation stage in a reaction tank and to leave a space for introducing a gaseous cooling medium into the gas stream between the two stages.

摘要： In a process for producing hydrocarbonaceous educts, the starting material is autothermally gasified by non-catalytic partial oxidation by adding oxygen-containing gas and hydrogen at temperatures of 1200 to 1500° C. and pressures of 15 to 100 barabs to obtain a raw gas containing H2 and CO as main components as well as the components CO2, H2O, CH4 and traces of H2S, COS, CnHm, N2 and Ar, and subsequently the CO contained in the raw gas is converted to CO2 and further H2 by adding steam. An improvement of the process consists in that in a pressure-swing absorption process the converted raw synthesis gas is separated directly, i.e. without passing through a wash for removing CO2 and H2S, into high-purity H2 and into a gas mixture containing H2S, CO2, H2, CO, CH4, Ar and N2, the gas mixture is supplied to the tail gas wash of a Claus process, the H2S separated is introduced into the feed gas of the Claus process, and the waste gas of the tail gas wash, mixed with the tail gas of the Claus process, is burnt.
摘要翻译：在制造含烃离子的方法中，通过在1200〜1500℃的温度和15〜100巴的压力下加入含氧气体和氢气，通过非催化部分氧化将原料自动气化，得到含有 H2和CO为主要成分，以及CO2，H2O，CH4和H2S，COS，CnHm，N2和Ar的痕量组分，随后通过加入蒸汽将原料气中所含的CO转化为二氧化碳，再加入H2。该方法的改进在于，在压力 - 挥发吸收过程中，转化的原始合成气被直接分离，即不经过用于除去CO 2和H 2 S的洗涤物转化成高纯度H 2并进入含有H 2 S，CO 2的气体混合物，H2，CO，CH4，Ar和N2，将气体混合物供应到Claus工艺的尾气洗涤，将分离的H 2 S引入Claus工艺的进料气体中，尾气的废气洗涤，与克劳斯过程的尾气混合燃烧。

摘要： A novel steam reformer unit design, a novel hydrogen PSA unit design, a novel hydrogen/nitrogen enrichment unit design, and novel processing scheme application are presented. The result of these innovations results in re-allocating most of the total hydrogen plant CO2 emissions load to high pressure syngas stream exiting the water gas shift reactor while minimizing the CO2 emissions load from the reformer furnace flue gas. As compared to the conventional 60/40 split of total CO2 emissions in syngas/flue gas streams for steam reformer based conventional hydrogen plant designs, the present invention results in 85/15 or better CO2 split. This will permit about 85% or better of the total CO2 emissions load to be captured from the syngas stream, using the conventional, well proven and cost effective amine scrubbing technology. Such 85% or better CO2 capture is much greater than the 55% to 60% maximum possible using conventional steam reformer based hydrogen plant technology. As CO2 recovery from high pressure syngas stream is much easier and cost effective as compared to that from low pressure reformer furnace flue gases, a major cost benefit for equivalent CO2 recovery results with the present invention.
摘要翻译：提出了一种新型的蒸汽重整单元设计，新型氢PSA单元设计，新型氢/氮浓缩单元设计和新型加工方案应用。这些创新的结果导致将氢气厂二氧化碳总排放量的大部分重新分配到离开水煤气变换反应器的高压合成气流中，同时最小化来自重整炉炉烟气的二氧化碳排放负荷。与常规氢气设计设计中用于基于蒸汽重整器的合成气/烟气流中总二氧化碳排放量的常规60/40分解相比，本发明导致85/15或更好的二氧化碳分离。这将允许从合成气流中捕获的总二氧化碳排放负荷约85％或更好，使用常规的，经过验证的和具有成本效益的胺洗涤技术。使用常规的基于蒸汽重整器的氢气技术，这种85％或更好的二氧化碳捕获量远大于最大可能的55％至60％。由于与来自低压重整炉烟道气相比，来自高压合成气流的二氧化碳回收更容易和成本有效，所以本发明的等效二氧化碳回收的主要成本优势。

摘要： From the CO2-containing stream of process gas obtained in a process for the treatment of a CO2-containing stream of process gas, which is obtained in the production of pure synthesis gas from raw gas in the partial oxidation of heavy oils, petroleum coke or wastes, or in the gasification of coal, or when processing natural gas or accompanying natural gas, CO2 is removed physisorptively or chemisorptively, and the solvent loaded with CO2 is expanded to a lower pressure for the desorption of CO2. In order to generate CO2 as pure as possible, the contaminated CO2 is condensed to at least 60 bar[a] or below its critical temperature to at least 70 bar[a], and the impurities contained in the liquid CO2 are removed by stripping with gaseous CO2 guided in counterflow.
