Advances in anode monitoring [mercury recycling]

Applications for programmable logic controllers and personal computers with the chloralkali industry continue to grow. Older multiplexed monitoring systems are being replaced with high-speed systems that can scan an entire cellroom within 2 s. Average cell voltages can be decreased by 0.25 V DC or more, resulting in significant power savings or production increases. The newer systems can be installed as an upgrade to existing systems to minimize the impact on mercury recovery plant operations.
