摘要： The invention relates to a method for treating sour waters containing hydrogen sulfide and ammonia in the dissolved state, for example from sour gas treatment facilities, treatment facilities for gases from Claus processes, refining processes, etc.
In a column (2) provided with internals for liquid/gas contacting, the sour water feedstock (1) is stripped using steam (3), then cooled by a cold liquid (9) and washed using cold water injection (10). This method allows to separate an ammonia-poor (5-5000 ppm) H 2 S gaseous effluent (11) and an H 2 S-lean (100-1000 ppm for example) purified water (12). The method is yet improved by adding a second column that receives the purified water from the first column and separates the hydrogen sulfide and the ammonia according to the method operated in the first column. The purified water from the second column is preferably partially injected into the first and/or the second column as wash water. The invention also relates to a facility for implementing the method according to the invention.

摘要： The invention is a process for removing sulfur from a gas containing sulfur compounds as H2S, SO2, COS, CS2..., in a quantity of up to 15%wt; it particularly concerns gases emanating from the Claus process. The process comprises a first hydrogenation of the sulfur compounds into H2S, the hydrogenation gas being used to regenerate a deactivated bed of oxidation catalyst, both being carried out at 200-500°C. After sulfur removal, the resulting gas undergoes a second hydrogenation step and then a direct oxidation step, said step being operated under the dew point of sulfur to trap the formed sulfur in the catalyst. In the further cycle, the gas streams are switched so as to regenerate the catalyst in run which is deactivated. In a preferred embodiment, the process operates in at least 2 identical reactors, each containing a bed of hydrogenation catalyst followed (in the sense of the flow of gas) by a direct oxidation catalyst bed containing an embedded heat exchanger.

摘要： The present invention relates to a gas-redirecting device (100) presenting an upper plane and a plurality of gas-redirecting tubes (3) comprising an inlet end and an outlet end. For each gas-redirecting tube, the orthogonal projections of the inlet end and the outlet end onto the upper plane have an over-lapping area of at most 50 % of the total area of the upper plane covered by the orthogonal projections. The present invention also relates to a liquid-gas contacting column (201) comprising such a gas-redirecting device (100), a floating support comprising such a liquid-gas contacting column, at least two packed beds (210, 220) and a method for improving the efficiency of a liquid-gas contacting column which is based on redirecting the gas from a wetted zone of a lower packed bed to a wetted zone of the higher packed bed, the liquid load through the wetted zone of the lower packed bed is different from the liquid load through the wetted zone of the higher packed bed.
