Title (EN) PROCESS FOR THE OXIDATION OF HYDROGEN SULPHIDE
(FR) PROCÉDÉ D'OXYDATION DU SULFURE D'HYDROGÈNE
Abstract: front page image
(EN) The present invention provides a process for the oxidation of hydrogen sulphide (H2S) in an H2S-containing hydrocarbon feed gas to elemental sulphur. In the process a H2S-containing hydrocarbon feed gas (10) and a sulphur dioxide containing gas (20) are contacted in a catalytic zone (3) at a temperature of 120 to 200°C, and a pressure of 4 to 200 bara, thereby forming elemental sulphur which is essentially in liquid form. A stream (30) containing the elemental sulphur and a first H2S-depleted gaseous stream (50) are removed from the catalytic zone (3). The first H2S-depleted gaseous stream (50) is separated, thereby obtaining a concentrated H2S-containing gaseous stream (60) and a second H2S-depleted gaseous stream (70). The concentrated H2S-containing gaseous stream (60) is incinerated, thereby obtaining a SO2-containing stream (80). At least a part of the SO2-containing stream (80) is used as the SO2-containing gas (20) supplied in step (b).
(FR) Cette invention concerne un procédé d'oxydation du sulfure d'hydrogène (H2S) dans un gaz d'alimentation hydrocarboné contenant du H2S en soufre élémentaire. Dans le procédé, un gaz d'alimentation hydrocarboné contenant du H2S (10) et un gaz contenant du dioxyde de soufre (20) sont mis en contact dans une zone catalytique (3) à une température de 120 à 200°C, et une pression de 4 à 200 bars, pour former ainsi du soufre élémentaire qui est essentiellement sous forme liquide. Un flux (30) contenant du soufre élémentaire et un premier flux gazeux appauvri en H2S (50) sont retirés de la zone catalytique (3). Le premier flux gazeux appauvri en H2S (50) est séparé, pour obtenir ainsi un flux gazeux contenant du H2S concentré (60) et un second flux gazeux appauvri en H2S (70). Le flux gazeux contenant du H2S concentré (60) est incinéré, pour obtenir un flux contenant du SO2 (80), une partie au moins dudit flux contenant du SO2 (80) étant utilisé à titre de gaz contenant du SO2 (20) chargé dans l'étape (b).
