EMOS® Pinhole Detector
AUTOMATIC START-UP AND SHUTDOWN PINHOLE DETECTION
One of the worst things that can happen in a cellroom is the mixing of hydrogen and chlorine gas through a perforated membrane. Damaged membranes significantly increase the risk of an explosion. Pinholes can also allow caustic soda to pass from the cathodic compartment into the anodic compartment, damaging the anodes and possibly causing outside leakages. Pinholes will always reduce the current efficiency of a cell as caustic soda is lost and forms unwanted by-products with the chlorine (e.g. chlorates, hypochlorites). Avoid safety hazards and serious equipment damage by detecting defective membranes as early as possible.
The EMOS® Pinhole Detector, during a start-up or following a shutdown, automatically detects membrane pinholes, analyzes their severity (from “Pinhole Level 0: No Membrane Pinholes” to “Pinhole Level 3: Severe Membrane Pinholes, Safety Issue”), and notifies the operator. These 4 severity levels provide more specific, actionable information when compared to other pinhole detection methods which typically do not feature severity levels.
Since membranes with pinholes are identified early on, you can then track and follow-up on them to minimize coating degradation and production losses. This also allows you to efficiently manage membrane replacement during planned shutdowns and avoid delays during plant start-ups. In addition, the EMOS® Pinhole Detector increases plant safety by helping you to avoid operating with weakened or damaged components.
