Abstract: A urea synthesis reactor is provided that comprises a casing extending along an axis and a first and a second inlet tube inserted through respective through openings of the casing and respectively connected, inside the casing, to a light phase distributor and to a heavy phase distributor configured to feed the reactor with a light phase containing carbon dioxide and a heavy phase containing ammonia, respectively; the light phase distributor comprises one or more tubular elements extending and/or distributed over the cross-section of the reactor and about the axis and provided with intake holes spaced apart from one another, so as to distribute said light phase in a plurality of intake points distributed transversely in the reactor and about the axis.

Abstract: A urea reactor tray having a base plate; and a number or quantity of hollow cup-shaped members, which project vertically from the base plate along respective substantially parallel axes perpendicular to the base plate, and have respective substantially concave inner cavities communicating with respective openings formed in the base plate; the tray having a number or quantity of first cup-shaped members, each of which extends axially between an open top end having the opening, and a closed bottom end, and has a lateral wall with through holes substantially crosswise to the axis, and a bottom wall which closes the closed bottom end and has no holes.
