Definitions

  • step E1) for separating insolubles uses at least two, and generally less than five, solid-liquid separation equipment in series and/or in parallel.
  • the presence of at least two solid-liquid separation equipment in series makes it possible to improve the removal of insolubles, while the presence of equipment in parallel makes it possible to manage the maintenance of said equipment and/or unclogging operations.
  • the mass ratio between the mass flow rate of the extraction solvent and the mass flow rate of the polymer solution which feeds step E3), preferably the clarified polymer solution, the washed polymer solution or the refined polymer solution, is advantageously between 0 0.05 and 20.0, preferably between 0.1 and 10.0 and more preferably between 0.2 and 5.0.
  • the bringing into contact between the polymer solution which feeds step E3), preferably the clarified polymer solution, the washed polymer solution or the refined polymer solution, and the extraction solvent can be carried out at several points of the section of extraction, that is to say by several injections of the polymer solution and/or of the extraction solvent at different points along the extraction section, it is then the sum of the flows injected which is taken into account in the calculation of the ratio.
