 Critical Process Control – Online Analysis of Silicate in Boiler Feed Waters using the Metrohm 811 Online IC Process Analyser
22 Jun 2009 Boiler and cooling tower scale is expensive to control and is caused by impurities precipitating out of the water on heat transfer surfaces or suspended solids in the water settling out on the metal and becoming hard. The presence of scale caused by silicates can cause overheating and failure of boiler tubes. If no action is taken then corrosion may occur underneath the boiler scale which reduces the operating efficiency, cause thermal damage, and enforce unscheduled down time of the plant. With online analysis, critical process parameters are constantly monitored allowing pre-emptive rather than reactive decisions to be made to treat the formation of scale. This enables the site to operate more efficiently and profitably, minimising the time spent off-line rectifying problems. Metrohm Online IC systems – designed for 24-7 use throughou...
