Abstract
L'invention a pour objet un procédé de préparation d'hydrocarbures alkylaromatiques dans lequel un hydrocarbure aromatique et une oléfine sont mis en contact avec un catalyseur solide contenant de l'acide phosphorique dans une zone de réaction 8 maintenue dans des conditions favorisant l'alkylation ; un courant d'effluent de la zone de réaction comprenant l'hydrocarbure aromatique et un hydrocarbure alkylaromatique étant introduits dans une première zone de fractionnement 10, un courant de queues comprenant l'hydrocarbure aromatique et l'hydrocarbure alkylaromatique étant retiré de la première zone de fractionnement à une première température et passant ensuite dans une seconde zone de fractionnement 29 à une pression plus basse et à une seconde température plus basse, caractérisé en ce qu'on détend en 24 le courant de queue en un point situé entre la première zone de fractionnement et la seconde zone de fractionnement, on fait passer le courant de queues dans un décanteur 26 et on élimine l'acide phosphorique libéré du bac de décantation, réduisant ainsi la quantité d'acide phosphorique pénétrant dans la seconde zone de fractionnement
