Title (EN) ACIDIC-GAS TREATMENT AGENT AND ACIDIC-GAS TREATMENT METHOD
(FR) AGENT DE TRAITEMENT DE GAZ ACIDE ET PROCÉDÉ DE TRAITEMENT DE GAZ ACIDE
(JA) 酸性ガス処理剤および酸性ガス処理方法
Abstract:
(EN) Provided is an acidic-gas treatment agent in which sodium hydrogen carbonate is used as a neutralizer for an acidic gas, wherein the acidic-gas treatment agent tends not to form into a cake and has exceptional peeling properties. The acidic-gas treatment agent contains sodium hydrogen carbonate and an anticaking agent for the sodium hydrogen carbonate, the anticaking agent in the acidic-gas treatment agent being carbon black and/or hydrophobic silica. The content of the anticaking agent is preferably 0.1-2.0 wt%. The average grain size of the hydrophobic silica is preferably 1−20 μm, and the average grain size of the carbon black is preferably 0.1−10 μm.
(FR) La présente invention concerne un agent de traitement de gaz acide dans lequel de l'hydrogénocarbonate de sodium est utilisé comme agent de neutralisation d'un gaz acide, l'agent de traitement de gaz acide ayant tendance à ne pas s'agglomérer et présentant d'exceptionnelles propriétés d'écaillage. L'agent de traitement de gaz acide contient de l'hydrogénocarbonate de sodium et un agent anti-agglomérant pour l'hydrogénocarbonate de sodium, l'agent anti-agglomérant dans l'agent de traitement de gaz acide étant du noir de carbone et/ou de la silice hydrophobe. La teneur en agent anti-agglomérant est de préférence de 0,1 à 2,0 % en poids. La taille moyenne des grains de silice hydrophobe est de préférence de 1 à 20 μm, et la taille moyenne des grains de noir de carbone est de préférence de 0,1 à 10 μm.
(JA) 酸性ガスの中和剤として炭酸水素ナトリウムを用いた酸性ガス処理剤であって、固結し難く、かつ剥離性にも優れた酸性ガス処理剤を提供する。炭酸水素ナトリウムと炭酸水素ナトリウムの固結防止剤とを含む酸性ガス処理剤であって、該固結防止剤がカーボンブラック及び/又は疎水性シリカである酸性ガス処理剤。固結防止剤の含有量は0.1~2.0重量%であることが好ましい。疎水性シリカの平均粒径は1~20μmで、カーボンブラックの平均粒径は0.1~10μmであることが好ましい。
