Title (EN) METHODS OF POLYOLEFIN SOLIDS RECOVERY
(FR) PROCÉDÉS DE RÉCUPÉRATION DE SOLIDES DE POLYOLÉFINE
Abstract:
(EN) Methods for separating gaseous components, such as unreacted hydrocarbon monomer and/or solvent, from polyolefin solids are provided. The methods include contacting a first stream including polyolefin solids and gaseous unreacted hydrocarbon monomer and/or solvent with a first purge gas in a gas-solid separation vessel to separate the gaseous unreacted hydrocarbon monomer and/or solvent from the polyolefin solids to produce a second stream including polyolefin solids substantially free of gaseous unreacted hydrocarbon monomer and/or solvent and a third stream including the gaseous unreacted hydrocarbon monomer and/or solvent. The first purge gas includes hydrocarbon monomer and/or solvent and has a temperature of at least about 70°C when entering the gas-solid separation vessel. Systems for carrying out such methods are also provided.
(FR) L'invention concerne des procédés de séparation de composants gazeux, tels qu'un monomère hydrocarboné n'ayant pas réagi et/ou un solvant, de solides de polyoléfine. Les procédés comprennent la mise en contact d'un premier courant comprenant des solides de polyoléfine et un monomère hydrocarboné gazeux n'ayant pas réagi et/ou un solvant avec un premier gaz de drainage dans un récipient de séparation gaz-solide afin de séparer le monomère hydrocarboné gazeux n'ayant pas réagi et/ou le solvant des solides de polyoléfine pour produire un deuxième courant comprenant des solides de polyoléfine sensiblement exempts de monomère hydrocarboné gazeux n'ayant pas réagi et/ou de solvant et un troisième courant comprenant le monomère hydrocarboné gazeux n'ayant pas réagi et/ou le solvant. Le premier gaz de drainage comprend le monomère hydrocarboné et/ou le solvant et a une température d'au moins environ 70 °C à l'entrée dans le récipient de séparation gaz-solide. L'invention concerne également des systèmes pour mettre en œuvre ces procédés.
