摘要：
The invention relates to a column (1) for the thermal treatment of a fluid, comprising: a cylindrical, vertically oriented column body (2) forming a column hollow chamber (3); and a material exchange base (4) arranged in the column hollow chamber (3), forming a collecting surface (5). The column (1) according to the invention is characterised by a circulation device (9) comprising: at least one outlet opening (10) formed in the column body (2) above the collecting surface (5); a circulation line (11) in fluid connection with the outlet opening (10); and at least one recirculation opening (14; 14-1 to 14-3) which is in fluid connection with the circulation line (11), and which is formed in the column body (2) above the collection surface (5). The invention also relates to a thermal separation method, wherein a column (1) of this type is used. With this separation method, a gas rises in the column and a liquid falls in the column, wherein the gas and/or the liquid contains in particular (meth)acrylmonomers.
