Abstract
The present disclosure includes a column (1) having a cylindrical, vertical column body (2) forming a column cavity (3), and a mass transfer tray (4) disposed in the column cavity (3) and forming a collecting area (5). The column (1) is characterized by a circulation device (9) having at least one drain orifice (10) formed in the column body (2) above the collecting area (5), a circulation line (11) in fluid connection with the drain orifice (10) and at least one recycling orifice (14; 14-1 to 14-3) which is in fluid connection with the circulation line (11) and is formed in the column body (2) above the collecting area (5). Also disclosed herein is a thermal separating process in which a gas ascends within a column (1) of the present disclosure, and a liquid descends within the column (1), said gas and/or liquid containing (meth)acrylic monomers.
