Abstract

See full text

Provided are a method and an apparatus for recovering (meth)acrylic acid. The recovering method is used to save the energy required for a process of recovering (meth)acrylic acid because a process of separating high-boiling point by-products can be omitted, and to minimize a possibility of (meth)acrylic acid polymerization during the process of recovering (meth)acrylic acid. Therefore, the recovering method is used to obtain (meth)acrylic acid with less energy in a high yield.
