Title (EN) METHOD AND APPARATUS FOR PARTIAL REMOVAL OF CONTAMINANTS FROM PROCESS GAS STREAM
(FR) PROCÉDÉ ET APPAREIL POUR L'ÉLIMINATION PARTIELLE DE CONTAMINANTS D'UN FLUX DE GAZ DE TRANSFORMATION
Abstract:
(EN) In order to overcome the limitations and problems that earlier methods for the partial removal of contaminants from a process gas stream have experienced, the following method steps are proposed: - conveying the process gas stream (12; 30; 44; 59; 72; 85) to an inlet of a scrubber (10; 38; 52; 63; 74; 93), in particular of a horizontal wet spray scrubber (10; 74), - distributing the process gas stream (12; 30; 44; 59; 72; 85) evenly across the inlet of the scrubber (10; 38; 52; 63; 74; 93), in particular evenly throughout the width of the inlet of the scrubber (10; 38; 52; 63; 74; 93), - providing a plurality of process gas streams partitioned from one another at the inlet of the scrubber (10; 38; 52; 63; 74) or before entering the scrubber (93), in particular forming at the inlet of the scrubber (10; 38; 74) a flow pattern of a plurality of process gas streams partitioned from one another, - feeding ozone (21; 32; 46; 61; 76; 91) into contact with selected ones of the partitioned gas streams in the scrubber (10; 38; 52; 74; 93) or downstream of the scrubber (63) to oxidize contaminants in the partitioned gas streams, in particular for treating a preselected percentage of the process gas stream (12; 30; 44; 59; 72; 85) entering the scrubber (10; 38; 52; 63; 74; 93), - removing the oxidized contaminants - from the selected partitioned gas streams and recombining the selected partitioned gas streams at least substantially free of contaminants with the remaining partitioned gas streams containing contaminants, or from, after recombining the selected partitioned gas streams with the remaining partitioned gas streams, from the recombined gas stream.
(FR) Afin de surmonter les limitations et les problèmes que les procédés antérieurs pour l'élimination de contaminants d'un flux de gaz de transformation ont connu, l'invention concerne les étapes de procédé suivantes : l'acheminement du flux de gaz de transformation (12; 30; 44; 59; 72; 85) vers une entrée d'un dépoussiéreur (10; 38; 52; 63; 74; 93), en particulier d'un dépoussiéreur par voie humide, à pulvérisation, horizontal (10; 74); la répartition du flux de gaz de transformation (12; 30; 44; 59; 72; 85) de manière uniforme sur toute l'étendue de l'entrée du dépoussiéreur (10; 38; 52; 63; 74; 93), en particulier de manière uniforme sur toute la largeur de l'entrée de celui-ci (10; 38; 52; 63; 74; 93); l'apport d'une pluralité de flux de gaz de transformation séparés les uns des autres à l'entrée du dépoussiéreur (10; 38; 52; 63; 74) ou avant d'entrer dans celui-ci (93), en particulier avec formation à l'entrée du dépoussiéreur (10; 38; 74) d'un motif de circulation constitué d'une pluralité de flux de gaz de transformation séparés les uns des autres; l'introduction d'ozone (21; 32; 46; 61; 76; 91) pour venir en contact avec des flux de gaz sélectionnés parmi les flux de gaz séparés présents dans le dépoussiéreur (10; 38; 52; 74; 93) ou en aval de celui-ci (63) pour oxyder des contaminants présents dans les flux de gaz séparés, en particulier pour le traitement d'un pourcentage présélectionné du flux de gaz de transformation (12; 30; 44; 59; 72; 85) entrant dans le dépoussiéreur (10; 38; 52; 63; 74; 93); l'élimination des contaminants oxydés hors des flux sélectionnés de gaz séparés et la recombinaison des flux sélectionnés de gaz séparés au moins sensiblement exempts de contaminants avec les autres flux de gaz séparés contenant des contaminants, ou l'élimination des contaminants, après recombinaison des gaz séparés sélectionnés avec les flux de gaz séparés restants, hors du flux de gaz recombiné.
