Title (EN) PROCESS AND APPARATUS FOR THE REMOVAL OF NITROGEN COMPOUNDS FROM A FLUID STREAM
(FR) PROCEDE ET APPAREIL D'EVACUATION DE COMPOSES AZOTES D'UN FLUX DE LIQUIDE
Abstract: front page image
(EN)Disclosed is a process and apparatus for removing nitrogen compounds from an alkylation substrate such as benzene. A conventional adsorbent bed (46, 114) can be used to adsorb basic organic nitrogen compounds and a hot adsorbent bed (72, 162) of acidic molecular sieve can adsorb the weakly basic nitrogen compounds such as nitriles. Water facilitates the adsorption of the weakly basic nitrogen compounds. Running an alkylation substrate stream (68, 8) from a fractionation column (40, 130) of elevated temperature and suitable water concentration to the hot adsorbent bed may be advantageous.
(FR)L'invention concerne un procédé et un appareil permettant d'évacuer des composés azotés d'un substrat d'alkylation tel que le benzène. On peut utiliser un lit adsorbant classique (46, 114) pour adsorber des composés azotés organiques basiques et un lit adsorbant chaud (72, 162) d'un tamis moléculaire acide pour adsorber des composés azotés faiblement basiques tels que les nitriles. L'eau facilite l'adsorption des composés azotés faiblement basiques. Il serait avantageux de faire couler vers le lit adsorbant chaud un flux de substrat d'alkylation (68, 8) à partir d'une colonne de fractionnement (40, 130) de température élevée et de teneur en eau appropriée.
