Patent

CA 2482925

The invention focuses on distributing the vapor/liquid flow that emerges from an inlet nozzle (23) across the tube sheet (24b) of an alkylation reactor or heat exchanger. The flow distributor (50) takes the two-phase flow that emerges from the inlet nozzle (23), turns it towards the tubesheet (4b) and delivers a uniform mixture across the tube sheet (24b). The flow distributor (50) is located in the channel head (24) of the reactor or heat exchanger. In order to dislodge the liquid film from the wall of the inlet nozzle (23), trip rings (52) and angular trip tabs are located internally in the flow distributor (50).

L'invention s'intéresse à la répartition du flux de vapeur ou de liquide en sortie d'une buse d'admission (23) traversant la plaque tubulaire (24b) d'un réacteur d'alkylation ou d'un échangeur thermique. Le répartiteur de flux prend le flux en deux phases à la sortie de la buse d'admission (23) le renvoie en direction de la plaque tubulaire (24b) et apporte un mélange uniforme sur la totalité de la plaque tubulaire (24b). Le répartiteur de flux (50) est situé dans la tête de canal (24) du réacteur ou de l'échangeur thermique. Pour chasser le film de liquide de la paroi de la buse d'admission (23), des bagues à décrochement (52) et des languettes à décrochement angulaire sont situées intérieurement dans le répartiteur de flux (50).
