ABSTRACT:
The spiral agitator in a vessel for separating steam from polymer is modified by providing holes in the ribbon flight at locations adjacent to the locations where the ribbon flight is supported by struts for the purpose of allowing the polymer to flow through the holes and sweep the area directly behind the struts to prevent gel buildup in these locations.
