Abstract[English]
The present invention relates to a system for distillation, specifically a system for distillation of a first raw product stream, preferably a raw methanol stream. Specifically, the system comprises a first concentration column arranged to provide a first product stream and a compressor is arranged to receive at least a portion of the first product stream, pressurise said stream, and provide a third product stream with an increased saturation temperature compared to the first product stream. A first reboiler is arranged to receive at least a first portion of the third product stream and provide heat energy to the first concentration column. In this way, the arrangement of the compressor and the first reboiler may result in a lowering of the energy contribution required from outside the system for distillation, which is necessary to drive the purification process of the first raw product stream. The invention further relates to a method for distillation of a first raw product stream and to a chemical plant.[French]
La présente invention concerne un système de distillation, en particulier un système de distillation d'un premier flux de produit brut, de préférence un flux de méthanol brut. En particulier, le système comprend une première colonne de concentration agencée pour fournir un premier flux de produit et un compresseur est agencé pour recevoir au moins une partie du premier flux de produit, mettre sous pression ledit flux, et fournir un troisième flux de produit présentant une température de saturation accrue par rapport au premier flux de produit. Un premier rebouilleur est agencé pour recevoir au moins une première partie du troisième flux de produit et fournir de l'énergie thermique à la première colonne de concentration. De cette manière, l'agencement du compresseur et du premier rebouilleur peut entraîner une diminution de l'apport énergique requise de l'extérieur du système de distillation, ce qui est nécessaire pour commander le processus de purification du premier flux de produit brut. L'invention concerne en outre un procédé de distillation d'un premier flux de produit brut et une installation chimique.
