Title
(EN) UREA REACTOR TRAY, REACTOR, AND PRODUCTION PROCESS
(FR) PLATEAU DE RÉACTEUR À URÉE, RÉACTEUR ET PROCÉDÉ DE PRODUCTION CORRESPONDANTS
Abstract
(EN)
A urea reactor tray (4) having a base plate (10); and a number of hollow cup-shaped members (11, 11A), which project vertically from the base plate (10) along respective substantially parallel axes (A) perpendicular to the base plate (10), and have respective substantially concave inner cavities (17, 37) communicating with respective openings (15) formed in the base plate (10); the tray (4) having a number of first cup-shaped members (11), each of which extends axially between an open top end (21) having the opening (15), and a closed bottom end (22), and has a lateral wall (23) with through holes (25) substantially crosswise to the axis (A), and a bottom wall (24) which closes the closed bottom end (22) and has no holes.
(FR)
L'invention concerne un plateau de réacteur à urée (4) présentant une plaque de base (10) et un certain nombre d'éléments formant cupules (11, 11A), qui font saillie verticalement à partir de la plaque de base (10) le long d'axes (A) sensiblement parallèles correspondants, perpendiculaires à la plaque de base (10), et qui présentent des cavités intérieures correspondantes sensiblement concaves (17, 37) en communication avec des ouvertures correspondantes (15) formées dans la plaque de base (10), le plateau (4) présentant un certain nombre de premiers éléments formant cupules (11), dont chacun s'étend axialement entre une extrémité supérieure ouverte (21) présentant l'ouverture (15), et une extrémité inférieure fermée (22), et présente une paroi latérale (23) à trous traversants (25) sensiblement perpendiculaires à l'axe (A), et une paroi formant fond (24) qui ferme l'extrémité inférieure fermée (22) et ne présente aucun trou.
