PRESSURE-BALANCED REACTION APPARATUS AND ITS OPERATION METHOD

PROBLEM TO BE SOLVED: To provide a pressure-balanced reaction apparatus having such a structure that the predetermined constitution can be kept without damaging a reaction vessel when a great pressure difference arises suddenly between the inside and outside of the reaction vessel since the operation is not controlled desirably or the reaction condition is changed, and to provide its operation method. SOLUTION: This pressure-balanced reaction apparatus has a double-vessel structure that the reaction vessel is arranged in a pressure-resistant vessel so that the first pressure in the reaction vessel is balanced with the second pressure in the space between the pressure-resistant vessel and the reaction vessel. A communicative passage is arranged for communicating the inside of the reaction vessel with the space between the pressure-resistant vessel and the reaction vessel when the differential pressure between the first pressure and the second pressure reaches the predetermined or higher value. A rupture disk which ruptures when the differential pressure between the first pressure and the second pressure reaches the predetermined or higher value and opens the communicative passage is arranged in the communicative passage.
