Abstract:
A plant (1) for recovering acrylic acid, which includes: a absorption column (201); a dissociation column (205); a first line (101) connected to the dissociation column (205); a second line (102) connecting the absorption column (201) and the dissociation column (205); a third line (103) feeding a substream of the mother acid obtained in the crystallization into the dissociation column (205); a fourth line (104) connecting the crystallization apparatus and the absorption column (201); and a fifth line (105) connecting the dissociation column (205) and the absorption column (201).
