Title (EN) A REACTOR-CONDENSER FOR THE SYNTHESIS OF UREA
(FR) RÉACTEUR-CONDENSEUR POUR LA SYNTHÈSE DE L'URÉE
Abstract:
(EN) A combined reactor and condenser for the synthesis of urea from ammonia and carbon dioxide, including a condenser section coupled to a reaction section, comprising inputs directed to said condenser section for a gaseous stream comprising ammonia and carbon dioxide and for a solution containing ammonium carbamate and liquid ammonia, and wherein the effluent of the condenser section is sent to the reaction section; the reaction section comprises a plurality of compartments and a plurality of mixers, at least one inside each of said compartments.
(FR) L'invention concerne un réacteur et un condenseur combinés pour la synthèse de l'urée à partir d'ammoniac et de dioxyde de carbone, comprenant une section de condenseur raccordée à une section de réaction, comprenant des entrées, dirigées vers ladite section de condenseur, pour un flux gazeux comprenant de l'ammoniac et du dioxyde de carbone et pour une solution contenant du carbamate d'ammonium et de l'ammoniac liquide, et l'effluent de la section de condenseur étant envoyé à la section de réaction; la section de réaction comprend une pluralité de compartiments et une pluralité de mélangeurs, au moins un à l'intérieur de chacun desdits compartiments.
