Abstract
A shell-and-tube reactor has a plurality of reaction tubes incorporated therein, a circulation path for the heating medium formed outside the reaction tubes, a heating medium introducing section provided on the upper part of the shell in the reactor and a heating medium discharge section provided on the lower part of the shell in the reactor, a back pressure applying means for the heating medium is further provided in the heating medium discharge section.
Claims13
A shell-and-tube reactor comprising:
- a chamber including:
- a gas inlet in an upper part of the chamber;
- a gas outlet in a lower part of the chamber;
- a shell between the gas inlet and the gas outlet, the shell being defined by an upper tube supporting plate, a lower tube supporting plate and a side wall of the chamber;
- a plurality of reaction tubes supported by the upper and lower tube supporting plates for introducing material gas from the gas inlet and discharging a reaction product to the gas outlet;
- a heating medium supplying system for supplying a liquid heating medium in the shell, the heating medium supplying system including:
- a heating medium introducing port provided on an upper part of the shell;
- a heating medium discharge port provided on a lower part of the shell;
- and
- a back pressure applier for imparting a back pressure to the heating medium in the shell so that a top of the liquid heating medium in the shell comes into contact with a lower surface of the upper tube supporting plate;
- and
- wherein the back pressure applier comprises a heating medium discharge pot arranged above the upper tube supporting plate.
