Abstract (en)

[origin: US2008121383A1] A heat exchanger for cooling reaction gas, wherein the respective ends of heat exchanger tubes, through which the reaction gas flows, are inserted in a respective tube plate and are surrounded by a jacket, at the two ends of which are provided a respective end chamber that is partially delimited by one of the tube plates and serves for the supply and withdrawal of the reaction gas; water, as cooling agent, flows through the inner chamber of the heat exchanger that is surrounded by the jacket and that is divided by a partition, extending perpendicular to the heat exchanger tubes, which extend through it, into two partial chambers disposed one after the other in the direction of flow of the reaction gas, each partial chamber being provided with its own supply connectors and outlet connectors for the cooling agent; boiling water flows through the partial chamber that is disposed on the inlet side for reaction gas and that is connected via a supply line and withdrawal lines with a water/steam drum; feed water flows through the partial chamber that is disposed on the outlet side for the reaction gas and that is connected via a withdrawal line with the water/steam drum. The partition between the two partial chambers permits the passage of the cooling agent that flows in the inner chamber of the heat exchanger.
