摘要： The present invention is directed to a process for the removal of aromatic hydrocarbons from a lean acid gas containing less than 20 mol.% of H2S, comprising : a) contacting the lean acid gas stream (1) with a H2S-selective liquid absorbent solution (29) in a first absorption zone (2) to produce a gas stream depleted in H2S (3) and an absorbent solution enriched in H2S (4), b) introducing the absorbent solution (4) into a non-thermic stripping zone (8) where it is contacted with a stripping gas stream (7) to obtain an absorbent solution depleted in C4 + aliphatic and aromatic hydrocarbons (9) and a stripping gas stream enriched in aromatic and C4 + aliphatic hydrocarbons (10), c) contacting the stripping gas stream (10)obtained in step b) with a H2S-selective liquid absorbent solution (28) in a second absorption zone (12) to obtain a stripping gas stream depleted in H2S (13), and an absorbent solution enriched in H2S (14) d) introducing the absorbent solution (9) obtained in step b) into a desorption zone (16) wherein the H2S-selective liquid absorbent solution (17) is recovered and a lean acid gas is produced.

摘要： Reaction mass containing mixed oxides of iron with one or more metals of groups IV to VII of the periodic table of the elements, wherein the mixed oxides are deposited in finely divided form on an inert refractory substrate with a high specific surface area. The invention also relates to methods for the manufacture of this reaction mass as well as the use thereof as a catalyst for the shift reaction of carbon monoxide with steam, forming carbon dioxide and hydrogen at an elevated temperature, and/or the removal of sulphur compounds from gases.

摘要： The invention concerns a method of advantageously and efficiently processing a flow of combustible sulphur-containing effluents while recovering the sulphur in elementary form. This method consists in particular of two consecutive steps: a step for the combustion of the flow of combustible sulphur-containing effluents with an excess oxidant gas, and a step for the post-combustion of the effluents from the combustion step with an acid gas. The flow of effluents from the post-combustion, which are free of chemical compounds that reduce the efficiency of the Claus catalysts, is processed in a Claus unit which recovers the sulphur in elementary form.

摘要： The invention relates to a fission reactor (1) for a Claus plant, comprising a fireproof lined boiler (9), which contains a combustion chamber (2) with an influx opening for a mixture of fuel gas, air and acid gas containing H2S, a catalyst chamber (10) with a catalyst bed and a chamber on the outflow side (11) comprising a gas outlet for a hot process gas that contains elemental sulphur. According to the invention, the boiler is configured as a horizontal cylindrical boiler, in which the combustion chamber (2), the catalyst chamber and the chamber on the outflow side (11) are located next to one another. The catalyst chamber is delimited on both sides in the flow direction by gas-permeable chequer bricks (14) and has a fill opening (15) on the shell side for introducing the catalyst bed.
