摘要： The present subject matter is directed to plasma dissociation of fluidic hydrogen sulfide to hydrogen and sulfur. A reactor is configured to have a plasma discharge and a vortex flow pattern. The plasma discharge provides energy to the hydrogen sulfide disassociation reaction and the vortex flow pattern helps to cause the condensation of sulfur molecules. The condensation of sulfur molecules helps to reduce the amount of energy input required to disassociate a certain amount of hydrogen sulfide. Additionally, the reactor may be configured to have a vortex flow pattern that provides for a recirculation zone in which relatively warm reaction products may exchange their heat energy with relatively cool input fluids.

摘要： This invention relates to a process of cleaning gas, in particular hydrocarbonaceous gas such as e.g. natural gas, which is contaminated with sulfur in the form of H2S and mercaptans as well as CO2. To create an improved process of cleaning hydrocarbonaceous gas, in which the energy consumption and hence the costs for generating a feed gas rather rich in H2S for the Claus plant can be decreased distinctly, it is proposed in accodance with the invention that before the absorption and regeneration plant (23) operated at a pressure of the feed gas of 20-80 bar abs another absorption plant (21) is provided, which operates with a selective solvent at the same pressure of 20-80 bar abs and which roughly desulfurizes the feed gas to 100-10,000 ppmV H2S, a solvent stream (17) loaded with hydrogen sulfide being withdrawn from this preceding absorption plant (21) and being supplied to a succeeding regeneration (22), that from the preceding absorption plant (21) a third gas stream (2), the roughly desulfurized crude gas, is supplied to the absorption and regeneration plant (23), and from this absorption and regeneration plant (23) the valuable gas (5) is withdrawn, which is supplied to a further use.

摘要： A process is described for decomposing hydrogen sulfide to produce hydrogen and sulfur. The process comprises mixing hydrogen sulfide with a volatile basic solution and introducing this mixture into an electrolytic cell having an anode and a cathode. By operation of this cell, hydrogen is formed at the cathode and a solution containing polysulfide is formed at the anode. The polysulfide-containing solution is separated and distilled to recover sulfur and the remaining volatile basic solution is recycled to be mixed with further hydrogen sulfide.

摘要： Metal impurities such as mercury, copper, lead, zinc, iron and cadmium that are contained in trace amounts in sulfur that have been recovered from zinc concentrates by direct pressure leaching or other hydrometallurgical processes are removed effectively by contacting the molten sulfur, as it is held at a temperature not lower than the melting point of sulfur, with activated alumina by passage through a packed layer of activated alumina or a filter coated with activated alumina, or by mixing with activated alumina under stirring or by passage through a fluidized layer of activated alumina. The method is capable of reducing the sum of metal impurities in the sulfur to 50 ppm or below, with contents of mercury being reduced to 1 ppm or less, to provide sulfur having a purity of at least 99.99%, which is advantageous for use as a raw material in the production of sulfuric acid and in other chemical processes.
