    摘要: A solution polymerization process that consumes less energy comprising: injecting feeds into one or more reactors to form a polyethylene in a single liquid phase, or optionally two liquid phases; deactivating the single or dual liquid phase; a first V/L separator separates the deactivated phase into a first bottom stream and a first overhead stream; the first overhead stream passes to a distillation column and the first bottom stream enters a second V/L separator, forming a second overhead stream and a second bottom stream; the second bottom stream enters a third V/L separator, forming a third overhead stream and a third bottom stream; the third bottom stream passes to polymer recovery; the second and third overhead stream are combined, condensed and purified, forming a purified solvent that is recycled to said reactors.
