ANALYTICAL INSTRUMENTS Protecting Power Station performance with gap-free conductivity monitoring data Swan Analytical UK Ltd. Unit 3 The Steading, Copthill Farm Deeping Road Stamford PE9 4TD

In an ideal world, continuous monitors would monitor continuously, but for some instruments downtime is necessary whilst service operations are undertaken. To overcome this, Swan Analytical Instruments has developed a new technology for power and industrial water/steam monitoring systems to enable uninterrupted operation. Chemists at the South Humber Bank Power Station (UK) have evaluated this innovative conductivity instrumentation, demonstrating its ability to avoid gaps in vital data streams, whilst also saving costs and lowering labour requirements. Swan's AMI CACE (Conductivity After...

In order to continuously monitor the potential threat from corrosive contaminants, it is necessary to remove the treatment chemicals from samples so that the underlying conductivity can be measured. This is achieved within the measurement instrument by passing the water sample through a cation exchange resin. Conductivity after Cation Exchange (CACE) In conventional CACE instruments a resin column changes contaminants into their acid form which amplifies the conductivity, allowing early detection of low level contaminants. Alkalizing agents can mask the contaminants as the column removes...

CACE monitoring - without resin replacement The innovative technology employed by Swan's AMI CACE is electro-deionisation (EDI); a process in which the ion exchange resin is regenerated in place, continuously. Ions present in the feed-water pass through ion exchange membranes to a concentrate stream, and are thereby separated from the sample. The protons and hydroxide ions needed for regeneration are generated by water electrolysis, which eliminates the requirement for regeneration chemicals, and this means that it is possible to eliminate alkalizing agent up to specific conductivities of...
