The present invention relates to a group of at least two gas-flow reactors (2<SUB>1</SUB>, 2<SUB>2</SUB>, 2'<SUB>2</SUB>, ..., 2<SUB>n</SUB>, 2'<SUB>n</SUB>) preferably with an ascending gas flow (3), which are supplied on the one hand, in parallel, with gas and on the other hand with a chemical neutralization and/or sorption agent of the pulverulent material type that is capable of adsorbing effluents present in said gas flow (3) by bringing said chemical neutralization and/or sorption agent in contact with said gas flow (3), said at least two reactors (2<SUB>1</SUB>, 2<SUB>2</SUB>, 2'<SUB>2</SUB>, ..., 2<SUB>n</SUB>, 2'<SUB>n</SUB>) having means (10) for collecting said chemical neutralization and/or sorption agent after it has been brought into contact with said gas flow (3), characterized in that at least one of said two reactors (2<SUB>l</SUB>, 2<SUB>2</SUB>, 2'<SUB>2</SUB>, ..., 2<SUB>n</SUB>, 2'<SUB>n</SUB>) has means (11) for discharging said chemical neutralization and/or or sorption agent, after having been brought into contact with said gas flow (3), said means (11) being connected to said collecting means (10), and means (7, 16) for injecting the chemical neutralization and/or sorption agent into at least one other of said at least two reactors (2<SUB>l</SUB>, 2<SUB>2</SUB>, 2'<SUB>2</SUB>, ..., 2<SUB>n</SUB>, 2'<SUB>n</SUB>). |
