Abstract
The present invention discloses a method for transforming a single reactor line into a double reactor line wherein the existing single reactor line is equipped with a flash tank for separating the solid polymer product from the flash vapor and wherein the vapor is sent to a system of at least two separating columns allowing the separation of its constituents into monomer, diluent and comonomer.
