Abstract
(Meth)acrolein or (meth)acrylic acid is collected by bringing a reaction gas () containing (meth)acrolein or (meth)acrylic acid obtained through a vapor-phase catalytic oxidation reaction into contact with an aqueous solution as a collecting solvent in a collecting tower main body (). The reaction gas () is supplied to the collecting tower main body () from two nozzles () facing each other, and is caused to collide in the collecting tower main body (). According to the present invention, (meth)acrolein or (meth)acrylic acid can be efficiently collected from a gas containing (meth)acrolein or (meth)acrylic acid while preventing polymerization.
