Abstract
This disclosure relates to a method of continuous recovery of (meth)acrylic acid and an apparatus used for the continuous recovery method. The continuous recovery method of (meth)acrylic acid according to the present invention may maintain a recovery rate of (meth)acrylic acid equivalent to that of the previous recovery method, and yet may significantly reduce energy consumption, and may minimize polymerization of (meth)acrylic acid in the recovery process, thus providing more improved operation stability.
