| description | A process to increase the capacity of the adsorbent in a normal paraffin adsorption separation system is presented. A tertiary flush stream is used to improve the capacity of the simulated moving bed system by flushing residual raffinate from the feed transfer line. The flushing removes residual raffinate containing desorbent that competes with the adsorption of normal paraffins from the feedstream. The flush stream is a material that will displace fluid in the column, but will not enter the pores of the adsorbent.
L'invention porte sur un procédé pour augmenter la capacité de l'adsorbant dans un système de séparation de paraffines normales par adsorption. Un courant de rinçage tertiaire est utilisé pour améliorer la capacité du système à lit mobile simulé par rinçage du raffinat résiduel hors de la ligne de transfert de la charge. Le rinçage enlève le raffinat résiduel contenant du désorbant qui est en compétition avec l'adsorption de paraffines normales provenant du courant de charge. Le courant de rinçage est une substance qui déplacera du fluide dans la colonne, mais qui n'entrera pas dans les pores de l'adsorbant. |
