<p>The present invention relates to a continuous recovery method of (meth)acrylic acid and to a device used in the method. According to the present invention, the continuous recovery method of (meth)acrylic acid introduces an extraction process between a process of absorbing (meth)acrylic acid and a process of separating a solvent, thereby drastically lowering energy consumed in separating the solvent. Specifically, the continuous recovery method of (meth)acrylic acid recirculates a raffinate of the extraction process, uses the same as an absorption solvent, and removes solid slurry by filtering the raffinate, thereby providing improved absorption efficiency and operation stability.</p> |
