Method for purifying (METH)acrylic acid, including optimized effluent treatment

Abstract

The present invention relates to the production of (meth)acrylic acid in a method for recovering (meth)acrylic acid based on the implementation of two separation steps. More particularly, the invention relates to combustion treatment in an oxidation reactor of the effluents from the first separation step, followed by partial condensation, partial recycling of the gases leaving the oxidizer upstream thereof, and purging of these carbon dioxide-rich gases, which can easily be recovered.
