Abstract
Procédé pour produire de l'acide sulfurique à partir de gaz contenant de l'hydrogène sulfuré obtenus lors de l'épuration de gaz de distillation de houille et contenant, en plus de l'hydrogène sulfuré, surtout du dioxyde de carbone, de l'acide cyanhydrique, de l'ammoniac et de la vapeur d'eau, dans lequel procédé le gaz est brûlé dans une installation de combustion 11, l'eau en excès est condensée par refroidissement (en 14 et 15, 18 et 20) et le gaz est de nouveau échauffé (en 16) et oxydé catalytiquement avec addition d'air (en 31), le dioxyde de soufre étant transformé en trioxyde de soufre et les gaz oxydés étant refroidis et condensés à l'aide d'acide sulfurique dilue (en 33). Le condensat obtenu lors du refroidissement des gaz (en 20) après l'opération de combustion est séparé dans une colonne de séparation 27 à l'aide d'air et l'air enrichi d'anhydride sulfureux sortant de la colonne est ramené dans le processus. Application : production d'acide sulfurique dans les cokeries.Process for producing sulfuric acid from gases containing hydrogen sulphide obtained during the purification of coal still gas and containing, in addition to hydrogen sulphide, especially carbon dioxide, hydrocyanic acid, ammonia and water vapor, in which the gas is burnt in a combustion plant 11, the excess water is condensed by cooling (in 14 and 15, 18 and 20) and the The gas is again heated (at 16) and catalytically oxidized with the addition of air (at 31), the sulfur dioxide being converted into sulfur trioxide and the oxidized gases being cooled and condensed using dilute sulfuric acid ( in 33). The condensate obtained during the cooling of the gases (at 20) after the combustion operation is separated in a separation column 27 using air and the air enriched with sulfur dioxide leaving the column is returned to the process. Application: production of sulfuric acid in coking plants.
