Abstract[English]
The specification describes a process for separating vinyl chloride monomer (VCM) from incondensables. The process involves the steps of compression, separation of an incondensables stream and a condensed VCM stream in one or more condensation stages, followed by further separation of VCM from the condensed VCM stream in a lights column. The lights column is equipped with a lights column condenser which produces a VCM-depleted lights column overheads stream and a recovered VCM stream which is returned to the lights column. The VCM-depleted lights column overheads stream is depressurised by a valve and then combined with the incondensables stream.[French]
La présente invention concerne un procédé de séparation de monomère de chlorure de vinyle (VCM) à partir de produits non condensables. Le procédé comprend les étapes de compression, de séparation d'un flux de produits non condensables et d'un flux de VCM condensé dans une ou plusieurs étapes de condensation, suivi d'une séparation supplémentaire de VCM du flux de VCM condensé dans une colonne de composés légers. La colonne de composés légers est équipée d'un condenseur de colonne de composés légers qui produit un flux de tête de colonne de composés légers appauvri en VCM et un flux de VCM récupéré qui est renvoyé à la colonne de composés légers. Le flux de tête de colonne de composés légers appauvri en VCM est dépressurisé par une vanne puis combiné avec le flux de produits non condensables.
