Title
(EN) SYSTEM FOR SULPHUR REMOVAL FROM A FLUE GAS
(FR) SYSTÈME POUR L'ÉLIMINATION DE SOUFRE D'UN GAZ DE CARNEAU
Abstract
(EN)
The system (1) for sulphur removal from a flue gas (FG), the system (1) comprising an absorber (2) comprising a vessel (3) having an inlet (4) and an outlet (5) for the flue gas (FG), nozzles (6) for spraying a slurry (7) through the flue gas (FG) and a slurry accumulation zone (9) at the lower part of the absorber (2), a reaction tank (15) having an oxidizing gas supply (16) into it and connected to the slurry accumulation zone (9), a buffer tank (28) connected to the reaction tank (15) and to the nozzles (6), for receiving the slurry (7) from the reaction tank (15) and supply the nozzles (6) with the slurry (7). The slurry accumulation zone (9) is connected to the reaction tank (15) by a duct (21) comprising a gas lock. The buffer tank (28) is connected to the reaction tank (15) by a communicating vessel passage (29).
(FR)
L'invention concerne un système (1) pour l'élimination du soufre d'un gaz de carneau (FG), le système (1) comprenant un absorbeur (2) comprenant une cuve (3) ayant une entrée (4) et une sortie (5) pour le gaz de carneau (FG), des buses (6) pour la pulvérisation d'une suspension épaisse (7) dans le gaz de carneau (FG) et une zone d'accumulation (9) de suspension épaisse au niveau de la partie inférieure de l'absorbeur (2), un réacteur (15) dans lequel se trouve un apport (16) de gaz oxydant et raccordé à la zone d'accumulation (9) de suspension épaisse, un réservoir tampon (28) raccordé au réacteur (15) et aux buses (6), pour la réception de la suspension épaisse (7) provenant du réacteur (15) et l'apport de la suspension épaisse (7) aux buses (6). La zone d'accumulation (9) de suspension épaisse est raccordée au réacteur (15) par un conduit (21) qui comprend un bouchon de vapeur. Le réservoir tampon (28) est raccordé au réacteur (15) par un passage communicant (29) entre récipients.
