Methods for the desvolatilizau00e7u00e3o a solution of polu00ecmero solvent and a polu00ecmero and unloading system for use with a thermal dryer. Methods for the desvolatilizau00e7u00e3o of polymer solutions have been invented, which include, in certain aspects, the dissolution of a viscous polymer in a solvent.Forming a polymer solvent solution, introducing the solution of polymer - solvent in a thermal dryer.By heating or by cooling the solution of polymer solvent in the thermal dryer, forming the product polymer with solvent removed and separated (and that may include other residues).The solvent separated with other waste if present, by vaporizing himself in the dryer thermal forming a steam.By removing the steam dryer heat and discharging the polymeric product of the thermal dryer.
