1. Safety installation for pressure-electrolysis apparatuses for the production of chlorine, alkali metal hydroxide solution and hydrogen, from an aqueous alkali metal chloride solution, this installation comprising devices (21) for measuring, adjusting and regulating the pressure in the anode chambers (5) and in the cathode chambers (6), these chambers being separated from one another by an ion-exchange membrane (10), the anode chambers being connected to separators (13) for separating chlorine and anolyte and the cathode chambers being connected with separators (14) for separating alkali metal hydroxide solution and hydrogen, characterised in that the anode chambers and cathode chambers additionally are connected to depressurisation vessel (43, 44) via depressurising valves (41, 42), the latter being provided with a differential-pressure instrumentation and control system (39, 40, 59). |
