    Abstract: A tube bundle apparatus for thermal exchange operations at high pressures and temperatures, under conditions of high aggressiveness of process fluids. The tube bundle includes a series of tubes whose internal wall includes a material selected from titanium, zirconium, or an alloy thereof, resistant to aggression of fluids, in which at least one of access chambers to the tube bundle is delimited by a wall including at least the following three metallic layers in succession: a) an external layer for tolerating pressure load, subject to corrosion by contact with the highly aggressive process fluid; b) an intermediate layer of stainless steel; (c) an anticorrosive lining in contact with the highly corrosive fluid, of a material selected from titanium, zirconium, or an alloy thereof. The apparatus can be particularly used as an exchanger/reactor, for example as a stripper, in the high pressure cycle of synthesis processes of urea.

    Abstract: A reactor including a reactor vessel and heat exchange tubes provided in the reactor vessel. The reactor vessel includes a tubesheet and is configured to receive a reaction fluid. The tubesheet has a first plate member configured to contact the reaction fluid and a second plate member configured to not contact the reaction fluid. Heat exchange tubes are provided in the reactor vessel and fixed to the first plate member. The heat exchange tubes are configured to receive a heat exchange medium. At least a portion of the first plate member configured to contact the reaction fluid is made of a metal that has a high corrosion-resistance against the reaction liquid, and the second plate member is made of a metal that has a low corrosion-resistance against the reaction liquid. The second plate member is detachably fixed to a remainder of the reactor vessel.
