PROCESS FOR CONCENTRATING POLYMER SOLUTIONS BY EVAPORATION

Polymer solutions are concentrated by evaporation, whereby the solution is heated under pressure and expanded through a nozzle into a coiled tube in which a decreasing pressure gradient is maintained in direction of flow and the gas velocity is increased and the temperature is raised above the melti...

More Information
Summary:Polymer solutions are concentrated by evaporation, whereby the solution is heated under pressure and expanded through a nozzle into a coiled tube in which a decreasing pressure gradient is maintained in direction of flow and the gas velocity is increased and the temperature is raised above the melting temperature of the polymer.
