Patent

CA 2559547

A feed nozzle assembly located near the bottom of an FCC riser reactor includes a plurality of feed nozzles, each feed nozzle including a discharge end which is angled toward the center of the riser. The angled discharged ends provide a combined discharge of hydrocarbon feed and atomization gas into the central portion of the riser thereby providing a desirable feed/catalyst contact condition while preventing impingement of the feed upon the riser walls.

L'invention concerne un assemblage d'ajutages d'alimentation situé près du fond d'un réacteur de tube goulotte FCC. Cet assemblage comprend une pluralité d'ajutages d'alimentation. Chaque ajutage d'alimentation comprend une extrémité d'évacuation qui forme un angle orienté vers le centre du tube goulotte. Les extrémités d'évacuation formant un angle injectent une charge combinée d'hydrocarbures et de gaz d'atomisation dans une partie centrale du tube goulotte, ce qui permet d'obtenir une condition de mise en contact de la charge/catalyseur voulue, tout en empêchant l'empiétement de la charge sur les parois du tube goulotte.
