Method for controlling the formation of polymer accumulations during distillation of a vinylaromatic monomer |
摘要 |
A method for controlling the formation of polymer accumulations in a distillation column comprising accumulating liquid phase material containing a polymerization inhibitor in a seal pan; providing the seal pan with liquid-pervious weep hole means through the bottom of the pan and allowing a controlled quantity of polymerization inhibitor-containing liquid phase material to seep through the weep hole means to the underside of the seal pan; and apparatus useful for practicing the disclosed method.
