Abstract
The present invention is directed to a process for separating hydrocarbons from a solution comprising a polymer. The process comprises the steps of: (A) withdrawing a solution stream comprising the polymer from a first vessel; (B) passing the solution stream into a flash vessel; (C) spraying the solution stream into droplets in the first flash vessel thereby establishing a stream of droplets within the flash vessel. The solution forms a downwards falling film within the flash vessel.
