Abstract:
A method of continuously recovering (meth)acrylic acid is provided. The method of continuously recovering (meth)acrylic acid according to the present disclosure enables use of a natural circulation type of reboiler which does not require an operating part in a destructive distillation process of recovering (meth)acrylic acid from a (meth)acrylic acid waste liquid, and therefore, stable operation of the continuous process may be achieved while simplifying equipment configuration.

Claim (Index 2):
The method of continuously recovering (meth)acrylic acid of  claim 1 , wherein the destructive distillation system  500  is operated such that the maximum height of the (meth)acrylic acid waste liquid in the (meth)acrylic acid waste liquid-receiving section  510  corresponds to 85% to 150% of the height of the top end of the heat exchanger tube of the natural circulation type of reboiler  550 .
