Abstract:
This disclosure relates to a method for continuous recovery of (meth)acrylic acid and an apparatus used for the recovery method. The method of continuous recovery of (meth)acrylic acid according to the present invention may remarkably reduce the amount of extraction solvent used and energy consumption of the total process, and minimize polymerization of (meth)acrylic acid in the recovery process, thus enabling stable recovery of (meth)acrylic acid and operation of a continuous process.
